I am using Centos 5.3 and squid version 2.6 Stable. I need to run the application in xp and it runs on the *.domainname.com url and using ports 80 and 1057. I have allowed the complete access to the xp client. And also made the redirect rule in the iptables.
In squid log files I am receiving the errors TCP_MISS/200 and TCP_MISS/404. The application runs by givig the proxy and it stops at the logon screen when we give the credentials. All the other browsing is going on fine. MSN Messenger and Yahoo messenger is also going on well.

This application is java based.
