Wow, this is a hot thread and I was also going to start a thread describing the same problem and happy to see our experts jump in.
I'm using AOLserver/3.3.1+ad13 and Jerry's patches...
It is an occasional and annoying problem that almost getting consistant: IE5.5 returns: "Cannot find server or DNS Error" but NN4.x NEVER returns an error.
I'm using alot of
file1 (form)-> file2 (process)
and at the end file2 does
ns_returnredirect "file1"
So I'm hoping for a solution that allows continued use of ns_returnredirect. Thank you. -Bob
