We are running BM 3.8 sp4 on NW 5.1sp8. After applying ir5 we are having
a problem where an internal web site stops working after the proxy
has been up for a while. Unloading and reloading the proxy causes it to
start working again. This is using IE.

I have tried Craig Johnson's proxy.cfg and the proxy.cfg that comes with
ir5. I have also tried the "http 1.1 through proxy" setting both ways.

I ran some traces and the proxy returns a tcp reset to the client
without even trying to contact the origin host. The proxy can ping the
host even when the client can't load the page.

This sounds similar to a recent thread, but in my case I don't even have
to load proxy with a '-cc' to get it working.

Any ideas appreciated.
