That is what I was intending to do. How do I find out if
whether or not the session cookie was accepted using the
built-in sessions? I found no function for such a test.
Check the SID constant after you've done session_start(). If it has an
empty value, the session is using cookies; otherwise, it'll have a value
of the form 'sessionname=sessionid', which is what is appended to the
URL (or inserted in forms as a hidden value) to propagate the
session-id.
Interesting idea.
This brings up a question. In order to decide whether to use cookies
or SID the built-in sessions must be testing to see if the user's
browser will accept the session cookies. How do they do that?
If they do it by the "2 page", send a cookie and see if it comes
back to the second page method we have been talking about, then
somehow, they are sureptiously inserting a forward to a non-
existant page! Right? How do they do that?
Best,
Craig
