session.cookie_path problem

Hi, I am having some trouble with my sessions cookie_path - it doesn't seem to work - or maybe I am not working, I don't know at the moment :) Apache 2.2.3 and PHP 5.3.2 as module. What I want to achieve, is 2 separate sessions in the same website - in different directories of course. My test setup is the following: http://sessiontest.dev.codefrog.dk/app1/.htaccess contains

       php_value session.cookie_path /app1/

http://sessiontest.dev.codefrog.dk/app1/index.php contains <?php

       session_start();

       $_SESSION['val1'] = "test1";

       print_r($_SESSION);
       print_r(session_get_cookie_params());

?> and http://sessiontest.dev.codefrog.dk/app2/.htaccess contains

       php_value session.cookie_path /app2/

http://sessiontest.dev.codefrog.dk/app2/index.php contains <?php

       session_start();

       $_SESSION['val2'] = "test2";

       print_r($_SESSION);
       print_r(session_get_cookie_params());

?> I visit /app1/ and $_SESSION contains 'val1' => 'test1' - as expected. I then visit /app2/ and $_SESSION then contains both 'val1' => 'test1' and 'val2' => 'test2' - not as expected. I would expect that each $_SESSION would only hold its own data. And I can see from the print_r(session_get_cookie_params()) that the cookie has changed its path like it should according to my .htaccess file. Am I missing something obvious? -- Kind Regards Lasse Brandt
