[squid-users] Squid and Perl and DENIED

I'm going to have a hemorrhagic stroke over this and I
hope I can get some insight from one of you kind
souls.

Here's my essential problem: I have two separate
squid proxies setup on two different VPSs. I
configured, compiled, installed, and setup both
identically (or thought I did, anyway). Through both
of these Squids I can proxy using Opera/Firefox just
fine, for http and https using whatever protocol is
needed (GET/POST/CONNECT). So far so good.

I also need to run some PERL http requests through
those proxies, and that's where it gets weird. Though
squid A, everything works perfectly fine. Though
squid B, only requests for http work, and everything
else is DENIED with (71) Connection Refused returned.
Given that I thought both squid proxies were setup the
same, I'm hurting to explain why one works and the
other doesn't. There's obviously some difference
between them but I can't fathom what. I even copied
the squid.conf file from one to the other without any
love. I tried turning off ALL the acl denial rules
just to see but still nothing.

That aside, I can't work out why Opera is fine but the
PERL isn't being accepted. There's obviously some
difference in the way the requests are coming in, but
the access.log files aren't helping me at all. Of
course, looking at the logs, Opera is using CONNECT to
get the https and Perl is trying to use GET/POST, but
squid-A is perfectly fine with this so I'm not sure
why squid-B isn't.

I've scoured the wikis, google, and documentation to
no avail. Maybe I'm missing something obvious? Is
this a problem with SSL keys or something? Any help is
greatly appreciated.

Here's the details:

for all my PERL requests)
