This release candidate improves the newly introduced support for HTTP/2.

HTTP/2 implementation detals:

  • Auto-detection of the HTTP protocol – HTTP/1.x or HTTP/2. No additional startup arguments required!
  • Support for HTTP/1.x and HTTP/2 requests on the same port number.
  • Support for HTTP and HTTPS on the same port number for HTTP/1.x and HTTP/2 requests.
  • Support for cleartext (“http” URIs) upgrade from HTTP/1.1 to HTTP/2.
  • Support for starting HTTP/2 for “https” URIs with the TLS Application-Layer Protocol Negotiation (ALPN) extension.
  • Support for starting HTTP/2 with “prior knowledge”.

Limitations:

  • The size in the Access Log is always 0 (zero) for HTTP/2 responses.
  • Request forwarding over HTTP/2 isn’t currently supported.
  • API Recorder only works with HTTP/1.x.

 

Additional changes and fixes:

  • Added support for case-insensitive URI pattern matching through “matchesIgnoreCase”.
- where: uriPathPattern
  matchesIgnoreCase: <uri-path-pattern>
