Hello, I have read a number of posts on how to resolve the hotmail login issues with an interception web cache but nothing has worked. I have tried the following 3 configurations in squid.conf, but after you enter your username and password then select sign-in, it goes to a blank page. header_access Accept-Encoding deny all acl hotmail_domains dstdomain .hotmail.msn.com .hotmail.com acl ie6 browser MSIE[[:space:]]6 header_access Accept-Encoding deny ie6 hotmail_domains acl hotmail dstdomain .hotmail.com always_direct allow hotmail I have also tried the iptables command to change the MTU size: /sbin/iptables -t nat -A POSTROUTING -p tcp -m tcp --tcp-flags SYN,RST SYN -j TCPMSS --set-mss 1476 When I direct the browser to the proxy it works fine, but I unfortunately must use an interception proxy. Has anyone got this fixed? Thanks, Bryan
