April 2009 Web Server Survey

In the April 2009 survey we received responses from 231,510,169 sites. This represents an increase of over 6 million sites when compared with last month, with Google and nginx accounting for almost all of the changes. Apache remains in the lead, as it has since 1996, with a total of over 106 million sites, followed by Microsoft-IIS with over 67 million and QQ with almost 29 million.

Some interesting language specific servers which can be seen in this month's survey include the Ruby application server Mongrel , with just over 41 thousand sites, and the python based Zope with almost 46 thousand. The Pike and C based Caudium has almost 14 thousand sites, the Erlang based Yaws has about 70, and a newcomer, Salvia , which is a lightweight web server framework written in Haskell , has one.

Following on from last month's mention of fake server headers, where we saw the venerable ZX_Spectrum/1997 (Sinclair_BASIC) , this month we have hi , appearing as the server banner for twitter , which is currently the 432nd most popular site amongst our toolbar community.
