Subject Re: How to keep track of sessions

Even though I disagree with the approach of persisting someone else's
proprietary internal objects, I assume that whoever asked the question
has a reasonable and well-thought out cause, so I try to help.

I'm still unclear as to why one would want to save the session object

to do with load-balancing, wanting to somehow augment / superimpose on
the built-in mechanism?
