Are you seing "urlParse: Deny access to port " in your logs?
If yes, find that text in src/url.cc and change the #if to a "#if 0"

If no, the following might be useful. It's supposed to ignore the port and
use default port for the protocol being requested. It's an HTTP violation
as the request from a client known to be this badly broken is not supposed
to be forwarded to the net in general.
(this is for 3-HEAD, 2.x may need some adjustment )

to use, patch squid and ./configure --enable-http-violations

Maybe alter the default port=0 value if you want a specific port, but be
aware that the parser is schema-neutral at this point and URL ports apply
equally to http://, https://, ftp:// , and others.
