Hi, We are using Squid as a http proxy. Web clients are able to load webpages through it without any problems. However, images linked in an HTML email hosted on a remote server (be it Apache or IIS) took a long time to load (2 to 10 minutes for 8 images, which is rather too much). Using web browsers (Firefox, Konqueror, IE6/7) to load the images worked fine, so we suspected the email clients (Outlook and Entourage) to be the culprits. BTW, this awfully looked like the same problem as this one : http://www.tech-archive.net/Archive/Mac/microsoft.public.mac.office.entourage/2007-04/msg00053.html Setting persistent_request_timeout to 0 : persistent_request_timeout 0 seconds solved the problem without any measurable adverse effect on our end. Are there any drawbacks to this workaround ? Maybe this should go into the FAQ... For the record, both Squid version squid-2.6.STABLE6-5.el5_1.2 (CentOS 5.1) and 3.0.STABLE1 (on CentOS 5.1) had the problem. Best regards, François Cami
