Cookie Question

[bonehead]

Greetings,

Is it possible to set a cookie to die if the user leaves my site *within
the current session*? I'm pretty sure the answer is "no", I just need
some confirmation.

Of course, if the answer is "yes", any pointers to documentation will be
gratefully accepted.

Re: Cookie Question

A session cookie will die after the browser is closed if you specify no
expiry date for the cookie.

If you use setcookie("name ", "var"); then the cookie will only be
available while the browser is open.

Thanks. I had this part already figured out. To reiterate,

Re: Cookie Question

I'd guess that would have to involve a hidden frame, and some onUnload
javascript code...

It is not possible to know when the user stops visiting your site as only
visits (i.e. HTTP requests) are actually sent to the web server. If someone
opens up a page on your site then jumps to another site this jump is a
request to the second site and nothing is sent to you.

This is not a PHP problem, it is an HTTP problem.
