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

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.
