I was reading about SPDY and the up-coming HTTP/2.0 and one of their main if not the most important one is speed.
Using a multiplexed protocol will cause a less painful connection re-initiation else then compression of headers. There was a small\long talk about the Host: header overhead on high performance routing\load-balancing servers. The use of Host: header was actually for a transit and compatibility from HTTP/1.0 to HTTP/1.1. There is a proposal to remove the Host: header and use a full URI in each request line(like proxy requests). It will reduce the number of bytes on the wire but how fast will it make the connection routing? I was hoping for an opinion about it from anyone here. I am not too familiar with haproxy and was wondering if there might be a simple way to instruct haproxy to demonstrate\measure the performance differences between using\parsing to ignoring the Host: header.
