General changes

HTTP/2

HTTP/2 in this release is stable. Not everything from the H2 specifications is supported. In particular

  • Priorities
  • Server PUSH
  • HTTP/2 over non-TLS

are not supported. In addition, HTTP/2 is only supported on the client side, outbound HTTP/2 is not supported yet (i.e. we only support proxying H2 to an HTTP/1.1 backend server (origin)). For some details on the implementation, see the TS-2729 Jira.

The following records.config settings are needed to enable HTTP/2 on trafficserver in 5.3.x.

       CONFIG proxy.config.http2.enabled INT 1

Additionally, there should be at least one TLS port configured in proxy.config.http.server_ports.

For example, 

       CONFIG proxy.config.http.server_ports STRING 80 443:ssl
