keeping session data across two domains
keeping session data across two domains
am 24.09.2007 21:58:14 von laredotornado
Hi,
I'm using PHP 4.4.4. I have two domains -- www.mydomain1.com and
www.mydomain2.com. Both point to the same IP address. I have two
pages on that IP -- first.php
session_start();
$_SESSION['test'] = "hello";
?>
and second.php
session_start();
print $_SESSION['test'];
?>
What I would like is when I first visit http://www.mydomain1.com/first.php
and then visit http://www.mydomain2.com/second.php to have the word
"hello" printed. Does anyone know how to adjust the above scripts or
my environment to make this possible?
Thanks, - Dave

I'll assume you're using cookies for sessions. In which case the
question is how you get a cookie from one site set when you are
accessing another.
The solution is to suck in pages from both mydomain1 and mydomain2 at
the point where the session is established. This could be done with
frames or by redirection. Life's probably a lot simpler if you pass
across the generated session id from one to the other, but you need to
be wary of session fixation. Otherwise you'll probably need to write
your own session handler to maintain 2 sessions alive and in sync.

hate to be dense, but how do you do that? - Dave

When you start the session on, say domain1, include an iframe with a
hidden div, and pass the sessionid to a page in domain2 which sets a
session cookie:
e.g. www.domain1.com/logged_in.php...
if (session_id()=='') {
create_new_session=true;
}
session_start();
// .... start doing the page header and body...
// ... at the very end of the page, before the
