If it's any help, I recently found myself in a situation where sessions
caused trouble relating to conflict errors.
What was happening, I think, was an intervening proxy server.
What I needed was:
user A on machine 1
user B on machine 2
user C on machine 3
username was from basic authentication. machine id was determined
automatically by the sessioning mechanism.
But machines 1,2,3 were sharing a proxy server. Let's call the proxy
server machine 7.
What I got was:
user A on machine 7
user B on machine 7
user C on machine 7
The result was unresolvable conflict errors, and I think it was only if
two or more users' responses in a field differed within a very short
time. I had to abandon sessions and put the user-specific data in the
relational database, keyed by username.
