Ari Pernick offers insight into the HTTP.SYS kernelization of (some of) the HTTP stack in Windows Server 2003:
Well, it's a scary change, but hopefully appropriate. The chunk of the HTTP stack that we put in the kernel was the routing part. In the same way that the kernel routes different socket ports to different applications and servers running in different accounts, Http.sys routes different url namespaces. [ Doubt's Log]He goes on to say a bit more about the whys and wherefores. Thanks for the update, Ari!
