I have two clients with identical configurations except for network speeds and internet speeds, but one is consistently experiencing something weird with proxy.nlm. It will run great for several days and maybe even a week. Then, users will start to get "page not found" errors. If they hit refresh in IE, the page will load just fine, but it will never load right the first time.

NetWare 6.5 SP4, BorderManager 3.8 SP4 and IR1. Also using Craig Johnson's custom proxy.cfg v21.

It seems that if I clear the cache, then the problem clears up for a while again.

Any ideas?
