on-rev server upgrade-related problems

[Phil Davis]

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
