This is what I got
This link does not contain the URL variable, so it will not set the session variable again, but the session variables value should not be changed.
Session Test = test
(When the page is first loaded, the session variable test will = NULL, when you click the first link, the session variable test will be set to test. Clicking the second link will only reload the page, the session variable test should still equal test, if it equals NULL, your server has a problem with session management.
Session ID = 9aq0et0bjugbqrqr7gqetm4fd3
(NOTE: if sessions are working correctly, the session ID should not change.)
