When http/2 support lands in haproxy, will http/2 support also be required on the back end to take advantage of it?
I'm hoping that I can leverage http/2 without immediate support on the back end. I would expect that the LAN connection between haproxy and the back end servers will be fast enough that the single http/2 connection can be used on the Internet-facing side with multiple http/1.1 connections on the back end, but I don't know if that kind of isolation will be possible. We do have plans to upgrade the back end to support http/2, but that may happen a lot slower than I would like. The back end servers for haproxy are Apache, with Tomcat behind those, so I have similar concerns there. Apache has http/2 support now, but Tomcat is lagging behind. Thanks, Shawn
