I meant to state that this problem occurs in some machines only, that is > on those machines attachment is not uploaded at all. Which ones? ie. How does the IP correlate to the tv_ip, sysadmin_ip, workstation_ip ACLs above? Any difference with attachment size? Any difference with how those machines are configured to use the proxy vs ones that work? (Manual setting? WPAD/PAC auto-configuration?) Any pattern with the client OS type and version? or the browser versions? Exactly what version of squid-3.5.x is being used? Running on what operating system? Self-built or a packaged Squid from .. where? If the above questions do not lead you towards an answer, are you able to get a packet trace to see where the pause is happening (client<->squid, or squid<->server), and whether the upload is actually hung, or just not being reported right by the browser.
