Returns the specified UrlMap resource.

HTTP request

GET https://compute.googleapis.com/compute/beta/projects/{project}/regions/{region}/urlMaps/{urlMap}

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project	string Project ID for this request.
region	string Name of the region scoping this request.
urlMap	string Name of the UrlMap resource to return.

Request body

The request body must be empty.

Response body

Represents a URL Map resource.

Compute Engine has two URL Map resources:

• Global
• Regional

A URL map resource is a component of certain types of cloud load balancers and Traffic Director:

• urlMaps are used by global external Application Load Balancers, classic Application Load Balancers, and cross-region internal Application Load Balancers.
• regionUrlMaps are used by internal Application Load Balancers, regional external Application Load Balancers and regional internal Application Load Balancers.

For a list of supported URL map features by the load balancer type, see the Load balancing features: Routing and traffic management table.

For a list of supported URL map features for Traffic Director, see the Traffic Director features: Routing and traffic management table.

This resource defines mappings from hostnames and URL paths to either a backend service or a backend bucket.

To use the global urlMaps resource, the backend service must have a loadBalancingScheme of either EXTERNAL, EXTERNAL_MANAGED, or INTERNAL_SELF_MANAGED. To use the regionUrlMaps resource, the backend service must have a loadBalancingScheme of INTERNAL_MANAGED. For more information, read URL Map Concepts.

If successful, the response body contains data with the following structure:

creationTimestamp	string [Output Only] Creation timestamp in RFC3339 text format.
name	string Name of the resource. Provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression [a-z]([-a-z0-9]*[a-z0-9])? which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
description	string An optional description of this resource. Provide this property when you create the resource.
selfLink	string [Output Only] Server-defined URL for the resource.
hostRules[]	object The list of host rules to use against the URL.
hostRules[].description	string An optional description of this resource. Provide this property when you create the resource.
hostRules[].hosts[]	string The list of host patterns to match. They must be valid hostnames with optional port numbers in the format host:port. * matches any string of ([a-z0-9-.]*). In that case, * must be the first character, and if followed by anything, the immediate following character must be either - or .. * based matching is not supported when the URL map is bound to a target gRPC proxy that has the validateForProxyless field set to true.
hostRules[].pathMatcher	string The name of the PathMatcher to use to match the path portion of the URL if the hostRule matches the URL's host portion.
pathMatchers[]	object The list of named PathMatchers to use against the URL.
pathMatchers[].name	string The name to which this PathMatcher is referred by the HostRule.
pathMatchers[].description	string An optional description of this resource. Provide this property when you create the resource.
pathMatchers[].defaultService	string The full or partial URL to the BackendService resource. This URL is used if none of the pathRules or routeRules defined by this PathMatcher are matched. For example, the following are all valid URLs to a BackendService resource: https://www.googleapis.com/compute/v1/projects/project/global/backendServices/backendService compute/v1/projects/project/global/backendServices/backendService global/backendServices/backendService If defaultRouteAction is also specified, advanced routing actions, such as URL rewrites, take effect before sending the request to the backend. However, if defaultService is specified, defaultRouteAction cannot contain any weightedBackendServices. Conversely, if defaultRouteAction specifies any weightedBackendServices, defaultService must not be specified. If defaultService is specified, then set either defaultUrlRedirect or defaultRouteAction.weightedBackendService. Don't set both. Authorization requires one or more of the following Google IAM permissions on the specified resource defaultService: compute.backendBuckets.use compute.backendServices.use
pathMatchers[].defaultRouteAction	object defaultRouteAction takes effect when none of the pathRules or routeRules match. The load balancer performs advanced routing actions, such as URL rewrites and header transformations, before forwarding the request to the selected backend. If defaultRouteAction specifies any weightedBackendServices, defaultService must not be set. Conversely if defaultService is set, defaultRouteAction cannot contain any weightedBackendServices. If defaultRouteAction is specified, don't set defaultUrlRedirect. If defaultRouteAction.weightedBackendServices is specified, don't set defaultService. URL maps for classic Application Load Balancers only support the urlRewrite action within a path matcher's defaultRouteAction.
pathMatchers[].defaultRouteAction.weightedBackendServices[]	object A list of weighted backend services to send traffic to when a route match occurs. The weights determine the fraction of traffic that flows to their corresponding backend service. If all traffic needs to go to a single backend service, there must be one weightedBackendService with weight set to a non-zero number. After a backend service is identified and before forwarding the request to the backend service, advanced routing actions such as URL rewrites and header transformations are applied depending on additional settings specified in this HttpRouteAction.
pathMatchers[].defaultRouteAction.weightedBackendServices[].backendService	string The full or partial URL to the default BackendService resource. Before forwarding the request to backendService, the load balancer applies any relevant headerActions specified as part of this backendServiceWeight.
pathMatchers[].defaultRouteAction.weightedBackendServices[].weight	integer (uint32 format) Specifies the fraction of traffic sent to a backend service, computed as weight / (sum of all weightedBackendService weights in routeAction) . The selection of a backend service is determined only for new traffic. Once a user's request has been directed to a backend service, subsequent requests are sent to the same backend service as determined by the backend service's session affinity policy. Don't configure session affinity if you're using weighted traffic splitting. If you do, the weighted traffic splitting configuration takes precedence. The value must be from 0 to 1000.
pathMatchers[].defaultRouteAction.weightedBackendServices[].headerAction	object Specifies changes to request and response headers that need to take effect for the selected backendService. headerAction specified here take effect before headerAction in the enclosing HttpRouteRule, PathMatcher and UrlMap. headerAction is not supported for load balancers that have their loadBalancingScheme set to EXTERNAL. Not supported when the URL map is bound to a target gRPC proxy that has validateForProxyless field set to true.
pathMatchers[].defaultRouteAction.weightedBackendServices[].headerAction.requestHeadersToRemove[]	string A list of header names for headers that need to be removed from the request before forwarding the request to the backendService.
pathMatchers[].defaultRouteAction.weightedBackendServices[].headerAction.requestHeadersToAdd[]	object Headers to add to a matching request before forwarding the request to the backendService.
pathMatchers[].defaultRouteAction.weightedBackendServices[].headerAction.requestHeadersToAdd[].headerName	string The name of the header.
pathMatchers[].defaultRouteAction.weightedBackendServices[].headerAction.requestHeadersToAdd[].headerValue	string The value of the header to add.
pathMatchers[].defaultRouteAction.weightedBackendServices[].headerAction.requestHeadersToAdd[].replace	boolean If false, headerValue is appended to any values that already exist for the header. If true, headerValue is set for the header, discarding any values that were set for that header. The default value is false.
pathMatchers[].defaultRouteAction.weightedBackendServices[].headerAction.responseHeadersToRemove[]	string A list of header names for headers that need to be removed from the response before sending the response back to the client.
pathMatchers[].defaultRouteAction.weightedBackendServices[].headerAction.responseHeadersToAdd[]	object Headers to add the response before sending the response back to the client.
pathMatchers[].defaultRouteAction.weightedBackendServices[].headerAction.responseHeadersToAdd[].headerName	string The name of the header.
pathMatchers[].defaultRouteAction.weightedBackendServices[].headerAction.responseHeadersToAdd[].headerValue	string The value of the header to add.
pathMatchers[].defaultRouteAction.weightedBackendServices[].headerAction.responseHeadersToAdd[].replace	boolean If false, headerValue is appended to any values that already exist for the header. If true, headerValue is set for the header, discarding any values that were set for that header. The default value is false.
pathMatchers[].defaultRouteAction.urlRewrite	object The spec to modify the URL of the request, before forwarding the request to the matched service. urlRewrite is the only action supported in UrlMaps for classic Application Load Balancers. Not supported when the URL map is bound to a target gRPC proxy that has the validateForProxyless field set to true.
pathMatchers[].defaultRouteAction.urlRewrite.pathPrefixRewrite	string Before forwarding the request to the selected backend service, the matching portion of the request's path is replaced by pathPrefixRewrite. The value must be from 1 to 1024 characters.
pathMatchers[].defaultRouteAction.urlRewrite.hostRewrite	string Before forwarding the request to the selected service, the request's host header is replaced with contents of hostRewrite. The value must be from 1 to 255 characters.
pathMatchers[].defaultRouteAction.urlRewrite.pathTemplateRewrite	string If specified, the pattern rewrites the URL path (based on the :path header) using the HTTP template syntax. A corresponding pathTemplateMatch must be specified. Any template variables must exist in the pathTemplateMatch field. -At least one variable must be specified in the pathTemplateMatch field You can omit variables from the rewritten URL The * and ** operators cannot be matched unless they have a corresponding variable name - e.g. {format=*} or {var=**}. For example, a pathTemplateMatch of /static/{format=**} could be rewritten as /static/content/{format} to prefix /content to the URL. Variables can also be re-ordered in a rewrite, so that /{country}/{format}/{suffix=**} can be rewritten as /content/{format}/{country}/{suffix}. At least one non-empty routeRules[].matchRules[].path_template_match is required. Only one of pathPrefixRewrite or pathTemplateRewrite may be specified.
pathMatchers[].defaultRouteAction.timeout	object Specifies the timeout for the selected route.

If not specified, this field uses the largest timeout among all backend services associated with the route. Not supported when the URL map is bound to a target gRPC proxy that has validateForProxyless field set to true.
pathMatchers[].defaultRouteAction.timeout.seconds	string (int64 format) Span of time at a resolution of a second. Must be from 0 to 315,576,000,000 inclusive. Note: these bounds are computed from: 60 sec/min * 60 min/hr * 24 hr/day * 365.25 days/year * 10000 years
pathMatchers[].defaultRouteAction.timeout.nanos	integer Span of time that's a fraction of a second at nanosecond resolution. Durations less than one second are represented with a 0 seconds field and a positive nanos field. Must be from 0 to 999,999,999 inclusive.
pathMatchers[].defaultRouteAction.retryPolicy	object Specifies the retry policy associated with this route.
pathMatchers[].defaultRouteAction.retryPolicy.retryConditions[]	string Specifies one or more conditions when this retry policy applies. Valid values are: 5xx: retry is attempted if the instance or endpoint responds with any 5xx response code, or if the instance or endpoint does not respond at all. For example, disconnects, reset, read timeout, connection failure, and refused streams. gateway-error: Similar to 5xx, but only applies to response codes 502, 503 or 504. connect-failure: a retry is attempted on failures connecting to the instance or endpoint. For example, connection timeouts. retriable-4xx: a retry is attempted if the instance or endpoint responds with a 4xx response code. The only error that you can retry is error code 409. refused-stream: a retry is attempted if the instance or endpoint resets the stream with a REFUSED_STREAM error code. This reset type indicates that it is safe to retry. cancelled: a retry is attempted if the gRPC status code in the response header is set to cancelled. deadline-exceeded: a retry is attempted if the gRPC status code in the response header is set to deadline-exceeded. internal: a retry is attempted if the gRPC status code in the response header is set to internal. resource-exhausted: a retry is attempted if the gRPC status code in the response header is set to resource-exhausted. unavailable: a retry is attempted if the gRPC status code in the response header is set to unavailable. Only the following codes are supported when the URL map is bound to target gRPC proxy that has validateForProxyless field set to true. cancelled deadline-exceeded internal resource-exhausted unavailable
pathMatchers[].defaultRouteAction.retryPolicy.numRetries	integer (uint32 format) Specifies the allowed number retries. This number must be > 0. If not specified, defaults to 1.
pathMatchers[].defaultRouteAction.retryPolicy.perTryTimeout	object Specifies a non-zero timeout per retry attempt. If not specified, will use the timeout set in the HttpRouteAction field. If timeout in the HttpRouteAction field is not set, this field uses the largest timeout among all backend services associated with the route. Not supported when the URL map is bound to a target gRPC proxy that has the validateForProxyless field set to true.
pathMatchers[].defaultRouteAction.retryPolicy.perTryTimeout.seconds	string (int64 format) Span of time at a resolution of a second. Must be from 0 to 315,576,000,000 inclusive. Note: these bounds are computed from: 60 sec/min * 60 min/hr * 24 hr/day * 365.25 days/year * 10000 years
pathMatchers[].defaultRouteAction.retryPolicy.perTryTimeout.nanos	integer Span of time that's a fraction of a second at nanosecond resolution. Durations less than one second are represented with a 0 seconds field and a positive nanos field. Must be from 0 to 999,999,999 inclusive.
pathMatchers[].defaultRouteAction.requestMirrorPolicy	object Specifies the policy on how requests intended for the route's backends are shadowed to a separate mirrored backend service. The load balancer does not wait for responses from the shadow service. Before sending traffic to the shadow service, the host / authority header is suffixed with -shadow. Not supported when the URL map is bound to a target gRPC proxy that has the validateForProxyless field set to true.
pathMatchers[].defaultRouteAction.requestMirrorPolicy.backendService	string The full or partial URL to the BackendService resource being mirrored to.

pathMatchers[].defaultRouteAction.corsPolicy.disabled	boolean If true, disables the CORS policy. The default value is false, which indicates that the CORS policy is in effect.
pathMatchers[].defaultRouteAction.faultInjectionPolicy	object The specification for fault injection introduced into traffic to test the resiliency of clients to backend service failure. As part of fault injection, when clients send requests to a backend service, delays can be introduced by a load balancer on a percentage of requests before sending those requests to the backend service. Similarly requests from clients can be aborted by the load balancer for a percentage of requests. timeout and retryPolicy is ignored by clients that are configured with a faultInjectionPolicy if: 1. The traffic is generated by fault injection AND 2. The fault injection is not a delay fault injection. Fault injection is not supported with the classic Application Load Balancer . To see which load balancers support fault injection, see Load balancing: Routing and traffic management features.

pathMatchers[].defaultRouteAction.maxStreamDuration	object Specifies the maximum duration (timeout) for streams on the selected route. Unlike the timeout field where the timeout duration starts from the time the request has been fully processed (known as end-of-stream), the duration in this field is computed from the beginning of the stream until the response has been processed, including all retries. A stream that does not complete in this duration is closed. If not specified, this field uses the maximum maxStreamDuration value among all backend services associated with the route. This field is only allowed if the Url map is used with backend services with loadBalancingScheme set to INTERNAL_SELF_MANAGED.
pathMatchers[].defaultRouteAction.maxStreamDuration.seconds	string (int64 format) Span of time at a resolution of a second. Must be from 0 to 315,576,000,000 inclusive. Note: these bounds are computed from: 60 sec/min * 60 min/hr * 24 hr/day * 365.25 days/year * 10000 years

The order by which path rules are specified does not matter. Matches are always done on the longest-path-first basis. For example: a pathRule with a path /a/b/c/* will match before /a/b/* irrespective of the order in which those paths appear in this list. Within a given pathMatcher, only one of pathRules or routeRules must be set.
pathMatchers[].pathRules[].service	string The full or partial URL of the backend service resource to which traffic is directed if this rule is matched. If routeAction is also specified, advanced routing actions, such as URL rewrites, take effect before sending the request to the backend.

The selection of a backend service is determined only for new traffic. Once a user's request has been directed to a backend service, subsequent requests are sent to the same backend service as determined by the backend service's session affinity policy. Don't configure session affinity if you're using weighted traffic splitting. If you do, the weighted traffic splitting configuration takes precedence. The value must be from 0 to 1000.
pathMatchers[].pathRules[].routeAction.weightedBackendServices[].headerAction	object Specifies changes to request and response headers that need to take effect for the selected backendService. headerAction specified here take effect before headerAction in the enclosing HttpRouteRule, PathMatcher and UrlMap. headerAction is not supported for load balancers that have their loadBalancingScheme set to EXTERNAL.

Any template variables must exist in the pathTemplateMatch field. -At least one variable must be specified in the pathTemplateMatch field You can omit variables from the rewritten URL The * and ** operators cannot be matched unless they have a corresponding variable name - e.g. {format=*} or {var=**}. For example, a pathTemplateMatch of /static/{format=**} could be rewritten as /static/content/{format} to prefix /content to the URL. Variables can also be re-ordered in a rewrite, so that /{country}/{format}/{suffix=**} can be rewritten as /content/{format}/{country}/{suffix}. At least one non-empty routeRules[].matchRules[].path_template_match is required. Only one of pathPrefixRewrite or pathTemplateRewrite may be specified.
pathMatchers[].pathRules[].routeAction.timeout	object Specifies the timeout for the selected route.

For example, disconnects, reset, read timeout, connection failure, and refused streams. gateway-error: Similar to 5xx, but only applies to response codes 502, 503 or 504. connect-failure: a retry is attempted on failures connecting to the instance or endpoint. For example, connection timeouts. retriable-4xx: a retry is attempted if the instance or endpoint responds with a 4xx response code. The only error that you can retry is error code 409. refused-stream: a retry is attempted if the instance or endpoint resets the stream with a REFUSED_STREAM error code. This reset type indicates that it is safe to retry. cancelled: a retry is attempted if the gRPC status code in the response header is set to cancelled. deadline-exceeded: a retry is attempted if the gRPC status code in the response header is set to deadline-exceeded. internal: a retry is attempted if the gRPC status code in the response header is set to internal. resource-exhausted: a retry is attempted if the gRPC status code in the response header is set to resource-exhausted. unavailable: a retry is attempted if the gRPC status code in the response header is set to unavailable.

pathMatchers[].pathRules[].routeAction.maxStreamDuration	object Specifies the maximum duration (timeout) for streams on the selected route. Unlike the timeout field where the timeout duration starts from the time the request has been fully processed (known as end-of-stream), the duration in this field is computed from the beginning of the stream until the response has been processed, including all retries. A stream that does not complete in this duration is closed. If not specified, this field uses the maximum maxStreamDuration value among all backend services associated with the route. This field is only allowed if the Url map is used with backend services with loadBalancingScheme set to INTERNAL_SELF_MANAGED.

pathMatchers[].pathRules[].customErrorResponsePolicy	object customErrorResponsePolicy specifies how the Load Balancer returns error responses when BackendServiceor BackendBucket responds with an error. If a policy for an error code is not configured for the PathRule, a policy for the error code configured in pathMatcher.defaultCustomErrorResponsePolicy is applied. If one is not specified in pathMatcher.defaultCustomErrorResponsePolicy, the policy configured in UrlMap.defaultCustomErrorResponsePolicy takes effect. For example, consider a UrlMap with the following configuration: UrlMap.defaultCustomErrorResponsePolicy are configured with policies for 5xx and 4xx errors A PathRule for /coming_soon/ is configured for the error code 404. If the request is for www.myotherdomain.com and a 404 is encountered, the policy under UrlMap.defaultCustomErrorResponsePolicy takes effect. If a 404 response is encountered for the request www.example.com/current_events/, the pathMatcher's policy takes effect. If however, the request for www.example.com/coming_soon/ encounters a 404, the policy in PathRule.customErrorResponsePolicy takes effect. If any of the requests in this example encounter a 500 error code, the policy at UrlMap.defaultCustomErrorResponsePolicy takes effect. customErrorResponsePolicy is supported only for global external Application Load Balancers.
pathMatchers[].pathRules[].customErrorResponsePolicy.errorResponseRules[]	object Specifies rules for returning error responses. In a given policy, if you specify rules for both a range of error codes as well as rules for specific error codes then rules with specific error codes have a higher priority. For example, assume that you configure a rule for 401 (Un-authorized) code, and another for all 4 series error codes (4XX). If the backend service returns a 401, then the rule for 401 will be applied. However if the backend service returns a 403, the rule for 4xx takes effect.
pathMatchers[].pathRules[].customErrorResponsePolicy.errorResponseRules[].matchResponseCodes[]	string Valid values include: A number between 400 and 599: For example 401 or 503, in which case the load balancer applies the policy if the error code exactly matches this value. 5xx: Load Balancer will apply the policy if the backend service responds with any response code in the range of 500 to 599. 4xx: Load Balancer will apply the policy if the backend service responds with any response code in the range of 400 to 499. Values must be unique within matchResponseCodes and across all errorResponseRules of CustomErrorResponsePolicy.
pathMatchers[].pathRules[].customErrorResponsePolicy.errorResponseRules[].path	string The full path to a file within backendBucket . For example: /errors/defaultError.html path must start with a leading slash. path cannot have trailing slashes.

pathMatchers[].pathRules[].customErrorResponsePolicy.errorResponseRules[].overrideResponseCode	integer The HTTP status code returned with the response containing the custom error content. If overrideResponseCode is not supplied, the same response code returned by the original backend bucket or backend service is returned to the client.
pathMatchers[].pathRules[].customErrorResponsePolicy.errorService	string The full or partial URL to the BackendBucket resource that contains the custom error content. Examples are: https://www.googleapis.com/compute/v1/projects/project/global/backendBuckets/myBackendBucket compute/v1/projects/project/global/backendBuckets/myBackendBucket global/backendBuckets/myBackendBucket If errorService is not specified at lower levels like pathMatcher, pathRule and routeRule, an errorService specified at a higher level in the UrlMap will be used. If UrlMap.defaultCustomErrorResponsePolicy contains one or more errorResponseRules[], it must specify errorService. If load balancer cannot reach the backendBucket, a simple Not Found Error will be returned, with the original response code (or overrideResponseCode if configured). errorService is not supported for internal or regional HTTP/HTTPS load balancers.
pathMatchers[].routeRules[]	object The list of HTTP route rules. Use this list instead of pathRules when advanced route matching and routing actions are desired. routeRules are evaluated in order of priority, from the lowest to highest number. Within a given pathMatcher, you can set only one of pathRules or routeRules.
pathMatchers[].routeRules[].priority	integer For routeRules within a given pathMatcher, priority determines the order in which a load balancer interprets routeRules. RouteRules are evaluated in order of priority, from the lowest to highest number. The priority of a rule decreases as its number increases (1, 2, 3, N+1). The first rule that matches the request is applied. You cannot configure two or more routeRules with the same priority. Priority for each rule must be set to a number from 0 to 2147483647 inclusive. Priority numbers can have gaps, which enable you to add or remove rules in the future without affecting the rest of the rules. For example, 1, 2, 3, 4, 5, 9, 12, 16 is a valid series of priority numbers to which you could add rules numbered from 6 to 8, 10 to 11, and 13 to 15 in the future without any impact on existing rules.

Only one of exactMatch, prefixMatch, suffixMatch, regexMatch, presentMatch or rangeMatch must be set. Regular expressions can only be used when the loadBalancingScheme is set to INTERNAL_SELF_MANAGED.
pathMatchers[].routeRules[].matchRules[].headerMatches[].rangeMatch	object The header value must be an integer and its value must be in the range specified in rangeMatch. If the header does not contain an integer, number or is empty, the match fails. For example for a range [-5, 0] -3 will match. 0 will not match. 0.25 will not match. -3someString will not match.

pathMatchers[].routeRules[].customErrorResponsePolicy	object customErrorResponsePolicy specifies how the Load Balancer returns error responses when BackendServiceor BackendBucket responds with an error. If a policy for an error code is not configured for the RouteRule, a policy for the error code configured in pathMatcher.defaultCustomErrorResponsePolicy is applied. If one is not specified in pathMatcher.defaultCustomErrorResponsePolicy, the policy configured in UrlMap.defaultCustomErrorResponsePolicy takes effect. For example, consider a UrlMap with the following configuration: UrlMap.defaultCustomErrorResponsePolicy are configured with policies for 5xx and 4xx errors A RouteRule for /coming_soon/ is configured for the error code 404. If the request is for www.myotherdomain.com and a 404 is encountered, the policy under UrlMap.defaultCustomErrorResponsePolicy takes effect. If a 404 response is encountered for the request www.example.com/current_events/, the pathMatcher's policy takes effect. If however, the request for www.example.com/coming_soon/ encounters a 404, the policy in RouteRule.customErrorResponsePolicy takes effect. If any of the requests in this example encounter a 500 error code, the policy at UrlMap.defaultCustomErrorResponsePolicy takes effect. When used in conjunction with routeRules.routeAction.retryPolicy, retries take precedence. Only once all retries are exhausted, the customErrorResponsePolicy is applied. While attempting a retry, if load balancer is successful in reaching the service, the customErrorResponsePolicy is ignored and the response from the service is returned to the client. customErrorResponsePolicy is supported only for global external Application Load Balancers.
pathMatchers[].routeRules[].customErrorResponsePolicy.errorResponseRules[]	object Specifies rules for returning error responses. In a given policy, if you specify rules for both a range of error codes as well as rules for specific error codes then rules with specific error codes have a higher priority. For example, assume that you configure a rule for 401 (Un-authorized) code, and another for all 4 series error codes (4XX). If the backend service returns a 401, then the rule for 401 will be applied. However if the backend service returns a 403, the rule for 4xx takes effect.
pathMatchers[].routeRules[].customErrorResponsePolicy.errorResponseRules[].matchResponseCodes[]	string Valid values include: A number between 400 and 599: For example 401 or 503, in which case the load balancer applies the policy if the error code exactly matches this value. 5xx: Load Balancer will apply the policy if the backend service responds with any response code in the range of 500 to 599. 4xx: Load Balancer will apply the policy if the backend service responds with any response code in the range of 400 to 499. Values must be unique within matchResponseCodes and across all errorResponseRules of CustomErrorResponsePolicy.
pathMatchers[].routeRules[].customErrorResponsePolicy.errorResponseRules[].path	string The full path to a file within backendBucket . For example: /errors/defaultError.html path must start with a leading slash. path cannot have trailing slashes.

pathMatchers[].routeRules[].customErrorResponsePolicy.errorResponseRules[].overrideResponseCode	integer The HTTP status code returned with the response containing the custom error content. If overrideResponseCode is not supplied, the same response code returned by the original backend bucket or backend service is returned to the client.
pathMatchers[].routeRules[].customErrorResponsePolicy.errorService	string The full or partial URL to the BackendBucket resource that contains the custom error content. Examples are: https://www.googleapis.com/compute/v1/projects/project/global/backendBuckets/myBackendBucket compute/v1/projects/project/global/backendBuckets/myBackendBucket global/backendBuckets/myBackendBucket If errorService is not specified at lower levels like pathMatcher, pathRule and routeRule, an errorService specified at a higher level in the UrlMap will be used. If UrlMap.defaultCustomErrorResponsePolicy contains one or more errorResponseRules[], it must specify errorService. If load balancer cannot reach the backendBucket, a simple Not Found Error will be returned, with the original response code (or overrideResponseCode if configured). errorService is not supported for internal or regional HTTP/HTTPS load balancers.

pathMatchers[].defaultCustomErrorResponsePolicy	object defaultCustomErrorResponsePolicy specifies how the Load Balancer returns error responses when BackendServiceor BackendBucket responds with an error. This policy takes effect at the PathMatcher level and applies only when no policy has been defined for the error code at lower levels like RouteRule and PathRule within this PathMatcher. If an error code does not have a policy defined in defaultCustomErrorResponsePolicy, then a policy defined for the error code in UrlMap.defaultCustomErrorResponsePolicy takes effect. For example, consider a UrlMap with the following configuration: UrlMap.defaultCustomErrorResponsePolicy is configured with policies for 5xx and 4xx errors A RouteRule for /coming_soon/ is configured for the error code 404. If the request is for www.myotherdomain.com and a 404 is encountered, the policy under UrlMap.defaultCustomErrorResponsePolicy takes effect. If a 404 response is encountered for the request www.example.com/current_events/, the pathMatcher's policy takes effect. If however, the request for www.example.com/coming_soon/ encounters a 404, the policy in RouteRule.customErrorResponsePolicy takes effect. If any of the requests in this example encounter a 500 error code, the policy at UrlMap.defaultCustomErrorResponsePolicy takes effect. When used in conjunction with pathMatcher.defaultRouteAction.retryPolicy, retries take precedence. Only once all retries are exhausted, the defaultCustomErrorResponsePolicy is applied. While attempting a retry, if load balancer is successful in reaching the service, the defaultCustomErrorResponsePolicy is ignored and the response from the service is returned to the client. defaultCustomErrorResponsePolicy is supported only for global external Application Load Balancers.
pathMatchers[].defaultCustomErrorResponsePolicy.errorResponseRules[]	object Specifies rules for returning error responses. In a given policy, if you specify rules for both a range of error codes as well as rules for specific error codes then rules with specific error codes have a higher priority. For example, assume that you configure a rule for 401 (Un-authorized) code, and another for all 4 series error codes (4XX). If the backend service returns a 401, then the rule for 401 will be applied. However if the backend service returns a 403, the rule for 4xx takes effect.
pathMatchers[].defaultCustomErrorResponsePolicy.errorResponseRules[].matchResponseCodes[]	string Valid values include: A number between 400 and 599: For example 401 or 503, in which case the load balancer applies the policy if the error code exactly matches this value. 5xx: Load Balancer will apply the policy if the backend service responds with any response code in the range of 500 to 599. 4xx: Load Balancer will apply the policy if the backend service responds with any response code in the range of 400 to 499. Values must be unique within matchResponseCodes and across all errorResponseRules of CustomErrorResponsePolicy.
pathMatchers[].defaultCustomErrorResponsePolicy.errorResponseRules[].path	string The full path to a file within backendBucket . For example: /errors/defaultError.html path must start with a leading slash. path cannot have trailing slashes.

pathMatchers[].defaultCustomErrorResponsePolicy.errorResponseRules[].overrideResponseCode	integer The HTTP status code returned with the response containing the custom error content. If overrideResponseCode is not supplied, the same response code returned by the original backend bucket or backend service is returned to the client.
pathMatchers[].defaultCustomErrorResponsePolicy.errorService	string The full or partial URL to the BackendBucket resource that contains the custom error content. Examples are: https://www.googleapis.com/compute/v1/projects/project/global/backendBuckets/myBackendBucket compute/v1/projects/project/global/backendBuckets/myBackendBucket global/backendBuckets/myBackendBucket If errorService is not specified at lower levels like pathMatcher, pathRule and routeRule, an errorService specified at a higher level in the UrlMap will be used. If UrlMap.defaultCustomErrorResponsePolicy contains one or more errorResponseRules[], it must specify errorService. If load balancer cannot reach the backendBucket, a simple Not Found Error will be returned, with the original response code (or overrideResponseCode if configured). errorService is not supported for internal or regional HTTP/HTTPS load balancers.
tests[]	object The list of expected URL mapping tests. Request to update the UrlMap succeeds only if all test cases pass. You can specify a maximum of 100 tests per UrlMap. Not supported when the URL map is bound to a target gRPC proxy that has validateForProxyless field set to true.

tests[].service	string Expected BackendService or BackendBucket resource the given URL should be mapped to. The service field cannot be set if expectedRedirectResponseCode is set.
tests[].expectedOutputUrl	string The expected output URL evaluated by the load balancer containing the scheme, host, path and query parameters. For rules that forward requests to backends, the test passes only when expectedOutputUrl matches the request forwarded by the load balancer to backends. For rules with urlRewrite, the test verifies that the forwarded request matches hostRewrite and pathPrefixRewrite in the urlRewrite action. When service is specified, expectedOutputUrl`s scheme is ignored. For rules with urlRedirect, the test passes only if expectedOutputUrl matches the URL in the load balancer's redirect response. If urlRedirect specifies httpsRedirect, the test passes only if the scheme in expectedOutputUrl is also set to HTTPS. If urlRedirect specifies stripQuery, the test passes only if expectedOutputUrl does not contain any query parameters. expectedOutputUrl is optional when service is specified.
tests[].expectedRedirectResponseCode	integer For rules with urlRedirect, the test passes only if expectedRedirectResponseCode matches the HTTP status code in load balancer's redirect response. expectedRedirectResponseCode cannot be set when service is set.
defaultService	string The full or partial URL of the defaultService resource to which traffic is directed if none of the hostRules match. If defaultRouteAction is also specified, advanced routing actions, such as URL rewrites, take effect before sending the request to the backend. However, if defaultService is specified, defaultRouteAction cannot contain any defaultRouteAction.weightedBackendServices. Conversely, if defaultRouteAction specifies any defaultRouteAction.weightedBackendServices, defaultService must not be specified. If defaultService is specified, then set either defaultUrlRedirect , or defaultRouteAction.weightedBackendService Don't set both. defaultService has no effect when the URL map is bound to a target gRPC proxy that has the validateForProxyless field set to true.
defaultRouteAction	object defaultRouteAction takes effect when none of the hostRules match. The load balancer performs advanced routing actions, such as URL rewrites and header transformations, before forwarding the request to the selected backend.

defaultRouteAction.weightedBackendServices[].weight	integer (uint32 format) Specifies the fraction of traffic sent to a backend service, computed as weight / (sum of all weightedBackendService weights in routeAction) . The selection of a backend service is determined only for new traffic. Once a user's request has been directed to a backend service, subsequent requests are sent to the same backend service as determined by the backend service's session affinity policy. Don't configure session affinity if you're using weighted traffic splitting. If you do, the weighted traffic splitting configuration takes precedence. The value must be from 0 to 1000.
defaultRouteAction.weightedBackendServices[].headerAction	object Specifies changes to request and response headers that need to take effect for the selected backendService. headerAction specified here take effect before headerAction in the enclosing HttpRouteRule, PathMatcher and UrlMap. headerAction is not supported for load balancers that have their loadBalancingScheme set to EXTERNAL.

For example, a pathTemplateMatch of /static/{format=**} could be rewritten as /static/content/{format} to prefix /content to the URL. Variables can also be re-ordered in a rewrite, so that /{country}/{format}/{suffix=**} can be rewritten as /content/{format}/{country}/{suffix}. At least one non-empty routeRules[].matchRules[].path_template_match is required. Only one of pathPrefixRewrite or pathTemplateRewrite may be specified.

For example, disconnects, reset, read timeout, connection failure, and refused streams. gateway-error: Similar to 5xx, but only applies to response codes 502, 503 or 504. connect-failure: a retry is attempted on failures connecting to the instance or endpoint. For example, connection timeouts. retriable-4xx: a retry is attempted if the instance or endpoint responds with a 4xx response code. The only error that you can retry is error code 409. refused-stream: a retry is attempted if the instance or endpoint resets the stream with a REFUSED_STREAM error code. This reset type indicates that it is safe to retry. cancelled: a retry is attempted if the gRPC status code in the response header is set to cancelled. deadline-exceeded: a retry is attempted if the gRPC status code in the response header is set to deadline-exceeded. internal: a retry is attempted if the gRPC status code in the response header is set to internal. resource-exhausted: a retry is attempted if the gRPC status code in the response header is set to resource-exhausted. unavailable: a retry is attempted if the gRPC status code in the response header is set to unavailable.

defaultRouteAction.faultInjectionPolicy	object The specification for fault injection introduced into traffic to test the resiliency of clients to backend service failure. As part of fault injection, when clients send requests to a backend service, delays can be introduced by a load balancer on a percentage of requests before sending those requests to the backend service. Similarly requests from clients can be aborted by the load balancer for a percentage of requests. timeout and retryPolicy is ignored by clients that are configured with a faultInjectionPolicy if: 1. The traffic is generated by fault injection AND 2. The fault injection is not a delay fault injection. Fault injection is not supported with the classic Application Load Balancer .

defaultCustomErrorResponsePolicy	object defaultCustomErrorResponsePolicy specifies how the Load Balancer returns error responses when BackendServiceor BackendBucket responds with an error. This policy takes effect at the load balancer level and applies only when no policy has been defined for the error code at lower levels like PathMatcher, RouteRule and PathRule within this UrlMap. For example, consider a UrlMap with the following configuration: defaultCustomErrorResponsePolicy containing policies for responding to 5xx and 4xx errors A PathMatcher configured for *.example.com has defaultCustomErrorResponsePolicy for 4xx. If a request for http://www.example.com/ encounters a 404, the policy in pathMatcher.defaultCustomErrorResponsePolicy will be enforced. When the request for http://www.example.com/ encounters a 502, the policy in UrlMap.defaultCustomErrorResponsePolicy will be enforced. When a request that does not match any host in *.example.com such as http://www.myotherexample.com/, encounters a 404, UrlMap.defaultCustomErrorResponsePolicy takes effect. When used in conjunction with defaultRouteAction.retryPolicy, retries take precedence. Only once all retries are exhausted, the defaultCustomErrorResponsePolicy is applied. While attempting a retry, if load balancer is successful in reaching the service, the defaultCustomErrorResponsePolicy is ignored and the response from the service is returned to the client. defaultCustomErrorResponsePolicy is supported only for global external Application Load Balancers.

If the backend service returns a 401, then the rule for 401 will be applied. However if the backend service returns a 403, the rule for 4xx takes effect.
defaultCustomErrorResponsePolicy.errorResponseRules[].matchResponseCodes[]	string Valid values include: A number between 400 and 599: For example 401 or 503, in which case the load balancer applies the policy if the error code exactly matches this value. 5xx: Load Balancer will apply the policy if the backend service responds with any response code in the range of 500 to 599. 4xx: Load Balancer will apply the policy if the backend service responds with any response code in the range of 400 to 499. Values must be unique within matchResponseCodes and across all errorResponseRules of CustomErrorResponsePolicy.
defaultCustomErrorResponsePolicy.errorResponseRules[].path	string The full path to a file within backendBucket . For example: /errors/defaultError.html path must start with a leading slash. path cannot have trailing slashes.

If overrideResponseCode is not supplied, the same response code returned by the original backend bucket or backend service is returned to the client.
defaultCustomErrorResponsePolicy.errorService	string The full or partial URL to the BackendBucket resource that contains the custom error content. Examples are: https://www.googleapis.com/compute/v1/projects/project/global/backendBuckets/myBackendBucket compute/v1/projects/project/global/backendBuckets/myBackendBucket global/backendBuckets/myBackendBucket If errorService is not specified at lower levels like pathMatcher, pathRule and routeRule, an errorService specified at a higher level in the UrlMap will be used. If UrlMap.defaultCustomErrorResponsePolicy contains one or more errorResponseRules[], it must specify errorService. If load balancer cannot reach the backendBucket, a simple Not Found Error will be returned, with the original response code (or overrideResponseCode if configured). errorService is not supported for internal or regional HTTP/HTTPS load balancers.
fingerprint	string (bytes format) Fingerprint of this resource. A hash of the contents stored in this object. This field is used in optimistic locking. This field is ignored when inserting a UrlMap. An up-to-date fingerprint must be provided in order to update the UrlMap, otherwise the request will fail with error 412 conditionNotMet. To see the latest fingerprint, make a get() request to retrieve a UrlMap. A base64-encoded string.
region	string [Output Only] URL of the region where the regional URL map resides. This field is not applicable to global URL maps. You must specify this field as part of the HTTP request URL. It is not settable as a field in the request body.
