[squid-users] hotmail attachment problem

Hi all,

I'm having problem with downloading attachments from hotmail.Users cant
download attachments from hotmail.But they can download from yahoo or
any other webmail.
It doesnt matter what the file extension is. .pdf, .html, .zip etc...
The access.log tells as below,

1129275547.316 2 10.1.0.247 TCP_DENIED/403 1521 GET
http://by110fd.bay110.hotmail.msn.com/cgi-bin/saferd/ICT8%2d5%2epdf? -
NONE/- text/html

1129275956.636 37 10.1.0.244 TCP_DENIED/403 1523 GET
http://by110fd.bay110.hotmail.msn.com/cgi-bin/saferd/ICT8%2d7A%2edoc?
-NONE/- text/html

etc...

thank you
koray
