Tutorial: mod_spdy with Apache2 on CentOS 6.4

vote

SPDY (pronounced "SPeeDY") is a new networking protocol whose goal is to speed up the web. It is Google's alternative to the HTTP protocol and a candidate for HTTP/2.0. SPDY augments HTTP with several speed-related features such as stream multiplexing and header compression. To use SPDY, you need a web server and a browser (like Google Chrome and upcoming versions of Firefox) that both support SPDY. mod_spdy is an open-source Apache module that adds support for the SPDY protocol to the Apache HTTPD server. This tutorial explains how to use mod_spdy with Apache2 on CentOS 6.4. read more...
