To add to this: When UseSession, for example, is called, the parameters (req, sessid) get populated via the publisher handler with the values from the <form>. So, since sessid is part of the form (<input type="hidden" name="sessid"....>), then sessid now get's passed this hidden value which came from the GetSID function. Or I could simply grab it by saying req.form['sessid']. ~= Chris =~ On Sun, 27 Feb 2005 13:43:38 -0500, Chris Jackson <christopher.jackson at gmail.com> wrote: > So how is the session id getting form GetSID to UseSession? > In other words, how does the sessid go from: > > GetSID => javascript => UseSession > > req.write simply sends the output to the browser.
