Subject [users@httpd] mod_proxy HTTP/2
Date Tue, 01 Mar 2016 13:18:31 GMT
I have Apache (2.4.18) setup and working fine with HTTP/2 on host-a. I can
establish HTTP/2 connections to host-a with any web browser. I also have
HTTP/2 and mod_proxy setup on host-b. I can proxy HTTP/1.1 requests from
host-b to host-a with any web browser. I can also establish HTTP/2
connections with host-b using any web browser. However, I can't get the
proxy request from host-b to host-a to talk HTTP/2. The connection between
host-b and host-a doesn't utilize the TLS ALPN extension so that the h2
protocol can be used. A packet capture shows that HTTP/1.1 is used for the
proxy connection between host-b and host-a despite the fact that virtual
host on host-a is configured to only accept h2 connections. Is there a way
to force the use of the TLS ALPN extension?

Thanks for your time,
