If you set the domain for the php session cookie, browsers seem to hold on to it for 30 seconds or so. It doesn't seem to matter if you close the tab or browser window.

So if you are managing sessions using something like the following it may be causing the cookie to hang in the browser for longer than expected.

ini_set("session.cookie_domain", 'www.domain.com');

The only way I've found to get rid of the hanging cookie is to remove the line of code that sets the session cookie's domain. Also watch out for session_set_cookie_params() function. Dot prefixing the domain seems to have no bearing on the issue either.

This might be a php bug as php sends a session cookie (i.e. PHPSESSID=b855ed53d007a42a1d0d798d958e42c9) in the header after the session has been destroyed. Or it might be a server propagation issue but I don't thinks so since my test were on a private servers.
