Webserver Usage Statistics / # of Apache Installations

Question

Does anyone know a site that details webserver usage statistics in the form of how many websites run Apache, how many IIS, how many Apache on Windows and how many on Linux?

I think it should be possible because AFAIK it is written in the HTTP header returned by the webserver or otherwise HTTP error / index pages may give a clue.

Addendum: what about the Operating System part?

Thanks for the Netcraft site, it is perfect for the Apache / IIS distribution.

The OS data from April 1999 might be a little dated, though. ;-) – Stobor Sep 08 '09 at 01:33
Possibly! :) Problem is this is the kind of survey companies want to charge for, not make available for free on the net. – Van Gale Sep 08 '09 at 07:28
