I have a very serious problem with the above. We have been running squid for approx 2 years with no problems. I am now getting "zero sized reply" from one web site which we need access to. I have followed all the advice on the FAQ and various other replies but it still persists. All other web sites are fine, or at least no user has complained. I do have a pix firewall as do my other offices. I can access the site through any of these(no proxy). When I remove my proxy(red hat 9 + squid-2.5.STABLE1-2) from this office I can also access the web site. From my proxy I can resolve it's address and telnet to it but I cannot access it from internet explorer. Help please.............................
