Web Server Survey November 2008 by Netcraft

Monthly Web Server Survey of Netcraft, an Internet services company providing Internet security services, including anti-fraud and anti-phishing services, application testing, code reviews, and automated penetration testing has been published. 

Result of this web server survey in November 2008 showing some interesting information of Yahoo Inc on web server market share. Yahoo Inc is now start identify their web servers as ‘YTS’ (Yahoo! Traffic Server). 

Netcraft Reports:

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 originally developed by Inktomi Corporation, which has been acquired by Yahoo Inc on 2002.  Now this traffic server used to serve over 12 billion requests per day and further development made by Yahoo’s own team. 

By introducing YTS on HTTP response header, Yahoo! seems to start their war to grab the world web server market share.  By the way, Google Inc used to identify their web server as ‘GWS’ (Google Web Server).
