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.
