If you are looking for an example of how to do it then libwww follows the
rules set in the HTTP/1.1 specification in handling URL expansion. The
algorithm goes like this
if ( Content-Base ) /* Must be absolute */
base = Content-Base
else if ( Content-Location ) /* Can be relative or absolute */
if ( Content-Location is absolute)
base = Content-Location
else
base = Request-URI /* Must be absolute */
endif
endif
expanded = URL taken relative to base
Content-base can be changed in the HTML document itself in which case you
just run the algorithm again.
libwww is available from
http://www.w3.org/pub/WWW/Library/
Thanks,
Henrik
