Anybody know how ASP.Net handles incoming requests from the ISAPI extension?

Hi all,

I'm trying to put together some notes on how ASP.Net works for myself and a
presentation I'm doing. One thing I can't seem to figure out is what happens
at the entry point of an ASP.Net request. What is the transition from the
unmanaged ISAPI code (in IIS 6) that runs in the default AppDomain that
makes call into the HttpRuntime object?

Something must be picking up the ISAPI ECP and parsing this information into
the various objects that make up the HttpContext. Request object members,
Server vars etc. Is there a specific object (documented or otherwise) that
does this?

Obviously this is internal, but it'd be interesting to follow this code
through.

Hi,

I think this answers it quite a bit:
