mod_spdy is an open-source Apache module that adds support for the SPDY protocol to the Apache HTTPD server. This allows for faster page loading and more efficient bandwidth utilization when loading https URLs in SPDY-enabled browsers.
SPDY (pronounced "SPeeDY") is a new networking protocol whose goal is to speed up the web. SPDY augments HTTP with several speed-related features that can dramatically reduce page load time:
* SPDY allows client and server to compress request and response headers, which cuts down on bandwidth usage when the similar headers (e.g. cookies) are sent over and over for multiple requests.
* SPDY allows multiple, simultaneously multiplexed requests over a single connection, saving on round trips between client and server, and preventing low-priority resources from blocking higher-priority requests.
* SPDY allows the server to actively push resources to the client that it knows the client will need (e.g. JavaScript and CSS files) without waiting for the client to request them, allowing the server to make efficient use of unutilized bandwidth.
NOTE:The SPDY protocol uses HTTPS, so your site needs to serve content over HTTPS in order to benefit from mod_spdy.
