How do your applet's current non-http TCP connections get through the
proxy?

They go through a specific port which bypasses the Proxy.

This is no longer a viable solution as many banks are saying "oh no you

Perhaps the solution is some JNI. Is there something in the Windows
API that will tell you the proxies?
