Session is always empty

I am using a tracking pixel in my project, firing this pixel will make a request to the server which will run a PHP script. At the PHP script I need to store a value to be always available for that script and for every call, So I am trying to use session but it seems like always NOT-Set!

session_start();
require_once("../../abc.php");

// Allow requests from different domains
header('Access-Control-Allow-Origin: *');

if(isset($_SESSION['log_file']) && !empty($_SESSION['log_file'])) {

    //Never goes here

} else {

    //Always goes here
}

Any Idea why the session is always Not-set? and what is the best session's alternative in this case?

Thanks.

Solution

  • The reason was that Empty session created on every http request. Also apc(u) facing the same problem. see the links:

    php-apcu (CGI/FastCGI) apc_fetch always return false
