sessions and domain names

[magic_hat60622]

Hi all. I've got an app that dumps a user id into a session after
successful login. the login page is http://www.mydomain.com/login.php.

If the user visits pages on my site without the www (i.e.,
http://mydomain.com/foo.php), the session works fine and login state is
maintained.

If he visits http://www.mydomain.com/foo.php, the app drops the
logged-in state.

Any idea how to fix this? I'm running php 4.4.1 w/ linux apache.

Re: sessions and domain names

I confess I wasn't aware of this problem, but I've never encountered
it. In addition to configuring your server to redirect to one or the
other, you could also try this:

I define the base url as a constant at the beginning of my scripts:

define('MY_BASE _URL', 'http://www.mydomain.co m/');

or, if you want to get more dynamic:

define('MY_BASE _URL', 'http://' . $_SERVER['HTTP_HOST'] . '/');

Then whenever you include a link on your page, just use:

<?php echo MY_BASE_URL . 'path/to/file.php'; ?>
