I was playing with the SessionID and was curious.
I basically did this.
Response.write session.SessionID
session.Abandon

When I refresh I get 19779783 in my page and it increments by one with each refresh, no dilema there but I started wondering...

Where is this number derived from?
Is it resettable by the programmer?
Does it turn over at 99999999?

Inquiring minds want to know.....
