Dear All, I am using squid 3.0 with ntlm authentication. Now when a user try to attach a file in gmail he got an authentication windows now even if he enter the user name and passwd the attachment is not uploading. Now if use https://mail.google.com/mail/ instead of http://mail.google.com/mail/ attachments are working. Please reply if any buddy faced the problem already.. Regards, Nitin B.
