Hello, I have squid up and running and the one issue which is causing headaches is the viewing of PDF files. From sites which are in my 'approved' list, if I click on a PDF link, my browser (Firefox) will just hang and I eventually have to kill it. If I do the same action without going through squid (same machine, same browser, same site, etc.) then the Acrobat plugin fires up and I can view the pdf without issue - so to me it's a squid related problem. Is there some port which I need to allow? If so I would think that Squid would give me a 'denied' error, not just cause the browser to hang up. Ideas? Regards, Randall
