Hi folk, I want to restric my users upload (Attachment) capacity. I'm using Squid Version 2.6.STABLE21 This is one part of my configuration: acl UPLIMIT req_header Content-Length [5-9][0-9]{5,} acl UPMETH method post http_access deny group1 UPMETH UPLIMIT This blocks anything => 500 KB I just tested in Yahoo mail and it works but it does not work in Gmail. I understood the Gmail use CONNECT method to upload the files. Any suggestion? Mohammad
