I have a site that runs entirely on session variables. It runs nicely.

It runs so nicely, that we've been growing a lot... Its time for a second
server. And unfortunately, some of our members are being kicked out
routinely when the load balancer between the servers alternates between the
servers.

Load Balancers have a setting against this but proxy connections and
programs such as Anonymizers interfere with this, and a switch may still
occur.

So the migration to client variables makes sense.

Assuming that the client data is stored in a db repository...

If a user is on one server and then is switched to the other
identical-architecture server (by the load balancer), they should retain
their status...?

Thanks for any thoughts... I have what seems to be a working version, but
I'm having a difficult time recreation the session switching situation..

Also, will programs such as Anonymizers cause this behavior, because they
change ip addresses? Is there any program, or command line method to clear
out the cache so that my computer will create a fresh connection and
potentially switch to the other server? I'm having a difficult time
emulating this problem.
