On one of our customers websites, they provide us access to a shared file
structure, for uploading and downloading project data as an alternative to
emailing it.

This site uses something called ProjectWise, which is not quite the same as
traditional FTP or HTTP file downloads.

Anyway, if we try to download a large file, it hangs, and eventually times
out with "504 Gateway Time-Out" error.

If we do the same when bypassing Border Managers proxy, it works fine,
albeit a little slow.

Is there a way of changing the Timeout that Border Manager uses before
giving the 504 error? It downloads using a seperate window that takes a good
while to come up with "Downloading Document", and BorderManager times out
too quickly on the larger files.

Any ideas? A simple setting somewhere I'd hope?
