My pleasure Jack, good karma for when I ask a question. :)

Hmm, I may be the wrong guy to help here but will give it a shot..

Sounds like the page is on your server right? So you're looking for a way 
to grab the result of URL on your own server, and since it's got SSI's on 
it you can't just grab the local file, is that right?

As said, Perl does this easily and I don't know C enough to know what it 
can offer for this need. If I had to do this therefore I'd just write a 
Perl pgm on say /home/jack/perl/


use LWP::Simple;
get 'http://myserver/myurl/';


Then within your C cgi pgm do a system call to and store the 
result. The perl script will capture apache's response to the get request, 
including any parsing of course and return the result just the same as for 
any other user agent. If you need to post instead of get that can be done 
as well, just a little bit more complicated.

BTW afaik the only significance of this being on a local server is that you 
might use localhost instead of the Internet domain name in crafting the URL 
to get if you think that might conserve bandwidth.
