In a post from March 6, 2003 in this group there was information about

getting Flash based applications working correctly by extracting some
useful
config options from the proxy.cfg posted by Craig Johnson (thank you,Craig!).
We have a customer in a very similar circumstance. I would like to
forward
to him only the part of that proxy.cfg that is necessary. We are not
BorderManager users, so I can only infer what the relevant settings
are.
I believe they may be the ones here...

[Extra Configuration]
# Next entry (from BM37Sp2) fixes problem browsing certain web sites
DoNotSendExtraCRLF = 1
# Next entry (from BM37Sp2) fixes problem browsing certain web sites
EnableIncomplete302ResponseFix = 0

That come from the proxy.cfg fiile here...

Can anyone verify these (or other config lines) that address getting
Flash
based applications working reliably?

I'd sure appreciate it.
Thanks in advance.
