November 2008 Web Server Survey

The November 2008 survey shows worldwide monthly growth of nearly three million websites, with responses now being received from a total of 185,167,897 sites.

Apache once again tops this month's growth, gaining 1.3 million sites to 93 million, but Microsoft-IIS follows closely gaining 1.1 million extra sites to reach 64 million. Google has grown by 509 thousand this month to approach the 11 million mark.

One interesting change this month is the appearance of 221,000 sites hosted by Yahoo! that now identify themselves as running on the Yahoo! Traffic Server proxy. Last month's survey found only 521 sites that claimed to be running on YTS.

Yahoo! is thought to use YTS to provide reverse proxy and connection management in a number of its services, although many of the company's sites were previously configured to omit the Server header in their HTTP responses. Yahoo! sites thought to use YTS include Bix, delicious, Flickr and Yahoo Groups.

Yahoo! Traffic Server is used to serve 12 billion requests per day. It was originally developed by Inktomi Corporation as a proxy cache for web traffic and streaming media. Websense acquired the technology behind Inktomi's proxy server, modifying it for use in their WebBlazer Web Threat Management System. Inktomi was then acquired by Yahoo! in 2002.
