I may have solved my own issue. It looks like my acl should use 'myport' instead of 'port' e.g. acl our_http_port port 80 should be: acl our_http_port myport 80 I'm not sure I understand the difference or why this works so I'd be happy to hear an explanation from anyone who knows. -andy > -----Original Message----- > From: Andy Litzinger > Sent: Wednesday, August 12, 2009 10:30 AM > To: Andy Litzinger; squid-users@xxxxxxxxxxxxxxx > Subject: RE: Reverse Proxy that listens and forwards to multiple ports > to the same backend server > > I should have mentioned I am running Squid3.0 Stable 18 > > > -----Original Message----- > > From: Andy Litzinger > > Sent: Wednesday, August 12, 2009 10:03 AM > > To: 'squid-users@xxxxxxxxxxxxxxx' > > Subject: Reverse Proxy that listens and forwards to multiple ports to > > the same backend server > > > > Hi all, > > I'm banging my head on what I think should be a simple config.
