It seems to be a function of the browser. I'm using IE 6 and
Netscape 6.2.1 on Win 2k.
If you start a new instance of IE by pressing CTRL-N, it seems to
send the cookie (i.e., session) to the server. If you start a new
instance of IE by, say, double-clicking the IE icon on the
desktop, and then you paste in the URL, it does *not* send the
cookie. It seems to me like it should. Of course, I assume you
have cookies enabled.
Using Netscape, it *always* seems to send the cookie correctly
whether you start it by CTRL-N or by double clicking the Netscape
icon.
It would be interesting to see what other browsers/platforms
yield, but I think the behavior you're seeing is specific to IE.
There's nothing wrong with your code, as far as I can tell. It's
rather nice, actually. :)
