Thanks Amos, The problem is when I use " request_body_max_size" it applies on all users. I'm using " ntlm_auth" to authenticate our domain users, is there any way to limit a particular users to attach big files into their emails? (yahoo/gmail, .....)

Take a read through: http://www.squid-cache.org/Doc/config/request_body_max_size/ CONNECT is a tunnel containing a whole separate stream of HTTP requests and replies wrapped in SSL (aka HTTPS or https://). In squid-2.6 there is nothing which you can do about it short of blocking HTTPS entirely. Amos
