I had an EMBPERL_COOKIE_PATH entry in the httpd.conf and I changed to
reflect the specific sub directory as well just in case that was the
issue, but the problem persists.  All the pages of the application
(site) are are in the same directory and %udat works correctly on all
the other pages.

I am wondering now if Embperl flushes the udat values if the page is not
completely rendered before a redirect or if that is at least the case in
this instance.  Is there something I send before the redirect to ensure
the session values hold?

How does a redirect and/or an http_headers_out effect udat, primarily if
they used on the first page visited prior to a full page being rendered?
In looking through the source I noticed that has no
SetupSession currently, just out of curiosity how or when would that be
