http servers: any method for getting the complete URL?

Is there any way for an http server to find out exactly what machine name
was in the URL used to access it? I looked in the NCSA httpd code, and it
didn't look like it could get any info outside of the "GET / HTTP1.0"
information. Basically, I'd like to set things up so that, for example, and return different root-level
indices, despite the fact that is a CNAME for (domain
names used for demonstration purposes only :)) Since that sort of DNS name
conversion takes place in the client, I'm not optimistic that it can get
this info, but I thought I'd ask.
