The following Media CDN features are now Generally Available:

  • Configuring Media CDN to follow origin redirects
  • Manipulating headers on a per-origin basis

For more information, see Failover and timeouts and Example: Failover with redirect following.

October 06, 2022

Media CDN now supports origin redirect following and origin header overrides in Preview.

You can improve performance and caching for frequent redirection by configuring origin redirect following in Media CDN. When configured, Media CDN follows origin redirect responses and caches the final retrieved object. For more information, see Configure following origin redirects.

You can also configure Media CDN to manipulate headers on a per-origin basis, which supports distinct host rewrites and static authorization headers for failover origins. For more information, see Failover and timeouts and Example: Failover with redirect following.

Media CDN now supports token-based client authentication and private external origin authentication for enhanced content protection and improved interoperability with multi-CDN and multi-cloud architectures in Preview.

Token-based authentication enables signing arbitrary data (like custom user identifiers), HMAC-based cryptography, and dual token exchange for token propagation through the duration of a playback session. For more information, see Prevent unauthorized distribution.

Private external origin authentication allows Media CDN to support private S3-compatible origins by dynamically generating signed requests with AWS Signature Version 4.

June 30, 2021

Cloud Media Edge now supports host, path, and tag based cache invalidation.

Cache tags allow you to invalidate the cache based on status codes, MIME type (Content-Type), and the origin the content was originally fetched from.

To learn how to use the gcloud SDK and REST API to invalidate cached responses, see the cache invalidation documentation.

June 25, 2021

Cloud Media Edge services now support the ability to match and rewrite incoming requests using pattern matching.

Pattern matching (or "wildcard matching") allows you to configure match rules with wildcard operators anywhere within a URL with pathTemplateMatch, capture path components, and rewrite URLs with pathTemplateRewrite before the request is sent to your origin.

Visit the pattern matching documentation to learn the pattern matching syntax, and see the suffix-matching example for how to match on file extensions.

June 16, 2021

Cloud Media Edge now supports connecting to private (non-public) Cloud Storage buckets. This allows you to restrict direct access to a storage bucket and/or only serve objects via your Media Edge services.

To learn how to configure private Cloud Storage access, visit the documentation.
