Now i kept trying without success.
I tried http_reply_access without any success.
Then
req_header . Log file shows request to be denied but I can still login with gtalk messenger.
This is what is the requested header that I can see in log file.
Code:
Connection:%20Keep-Alive%0d%0aContent-Length:%200%0d%0aHost:%20filetransferenabled.mail.google.com%0d%0aUser-Agent:%20Google%20Talk%0d%0a
And this is the acl in squid file. I am doubting my regular expression for comparing the User Agent. Can anyone help with the regular expression so that it matches google talk anywhere in the user agent field even with some trailing or succeeding characters?
Code:
acl gtalk_ban req_header User-Agent -i .Google .Google\ Talk .%20Google%20Talk%0d%0a
Sorry I am bad with regex.
