public sealed class HttpRouteRule : IMessage<HttpRouteRule>, IEquatable<HttpRouteRule>, IDeepCloneable<HttpRouteRule>, IBufferMessage, IMessage

Reference documentation and code samples for the Compute Engine v1 API class HttpRouteRule.

The HttpRouteRule setting specifies how to match an HTTP request and the corresponding routing action that load balancing proxies perform.

Properties

Description

public string Description { get; set; }

The short description conveying the intent of this routeRule. The description can have a maximum length of 1024 characters.

Property Value
TypeDescription
string

HasDescription

public bool HasDescription { get; }

Gets whether the "description" field is set

Property Value
TypeDescription
bool

HasPriority

public bool HasPriority { get; }

Gets whether the "priority" field is set

Property Value
TypeDescription
bool

HasService

public bool HasService { get; }

Gets whether the "service" field is set

Property Value
TypeDescription
bool

HeaderAction

public HttpHeaderAction HeaderAction { get; set; }

Specifies changes to request and response headers that need to take effect for the selected backendService. The headerAction value specified here is applied before the matching pathMatchers[].headerAction and after pathMatchers[].routeRules[].routeAction.weightedBackendService.backendServiceWeightAction[].headerAction 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.

Property Value
TypeDescription
HttpHeaderAction

MatchRules

public RepeatedField<HttpRouteRuleMatch> MatchRules { get; }

The list of criteria for matching attributes of a request to this routeRule. This list has OR semantics: the request matches this routeRule when any of the matchRules are satisfied. However predicates within a given matchRule have AND semantics. All predicates within a matchRule must match for the request to match the rule.

Property Value
TypeDescription
RepeatedFieldHttpRouteRuleMatch

Priority

public int Priority { get; set; }

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.

Property Value
TypeDescription
int

RouteAction

public HttpRouteAction RouteAction { get; set; }

In response to a matching matchRule, the load balancer performs advanced routing actions, such as URL rewrites and header transformations, before forwarding the request to the selected backend. If routeAction specifies any weightedBackendServices, service must not be set. Conversely if service is set, routeAction cannot contain any weightedBackendServices. Only one of urlRedirect, service or routeAction.weightedBackendService must be set. URL maps for Classic external HTTP(S) load balancers only support the urlRewrite action within a route rule's routeAction.

Property Value
TypeDescription
HttpRouteAction

Service

public string Service { get; set; }

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. However, if service is specified, routeAction cannot contain any weightedBackendServices. Conversely, if routeAction specifies any weightedBackendServices, service must not be specified. Only one of urlRedirect, service or routeAction.weightedBackendService must be set.

Property Value
TypeDescription
string

UrlRedirect

public HttpRedirectAction UrlRedirect { get; set; }

When this rule is matched, the request is redirected to a URL specified by urlRedirect. If urlRedirect is specified, service or routeAction must not be set. Not supported when the URL map is bound to a target gRPC proxy.

Property Value
TypeDescription
HttpRedirectAction
