It make sense and yes I understood that was what you want.
To do it you need a redirector which re-writes the URL

  http_port 80 accel defaultsite=www.jakesite.com

with a url_rewriter_program and location_rewriter_program

for their config settings see "OPTIONS FOR URL REWRITING" in
http://www.squid-cache.org/Versions/v2/2.6/cfgman/

Once that is done the URL are changed to squid retrieves the pages from
search.jakesite.com:8000 as any normal web request.
