Issue Maintaining Logged in State

Without seeing your session code it is hard to try and fix your problem.

This is how you can do it for all web browsers.

PHP Code:

header("Content-Type: application/json");
header("Expires: 0");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache"); 


If the 0 in the header expires isn't working on expires due to old browsers not understanding it, 
you can try putting the date to a time in the past.

PHP Code:

header("Content-Type: application/json");
header("Expires: on, 01 Jan 1970 00:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache"); 


What did you Try? What did you Get? What did you Expect?
