on-rev server upgrade-related problems

[Ralph DiMola]

I also think I remember script only stacks causing problems on LC Server.

Thank you all for so many great questions and responses! I don't have time
to give a comprehensive response right now but (1) I'll whittle away at it
and (2) all your comments renew my hope that a solution is out there waiting
for me to find it.

Quick responses:

- I too would start by going back to LC 6.6.x on the server if I could, but
apparently the recent server upgrades - new hardware running LC
9.5.1 - are not backward compatible. That's what I'm told at least.

- The LC client app is POSTing a request to an LC CGI system on an on-rev
server. The server system assembles a data packet (normally an encoded
array), encrypts & encodes it and writes it back to the client. 
The packet can be any size up to maybe a megabyte or two, but that would be
pretty big. Normally the packet size is no more than a few hundred KB.

Thanks again -
Phil
