Got it.  The problem was that I set a custom cookie at first access
which was apparently colliding with the session cookie in most
people's browsers.  I guess the custom cookie will need to be set at
second access.

I'm having a similar problem where the session changes whenever the
first access results in a [bounce].  My redirects are done in IC in an
autoload, and I thought that must be the problem, but I moved the
redirects all the way to the very end of BOTTOM_TEMPLATE and the
problem persists.  Any ideas on this one?
