PHP session is not working with Firefox

Question

This happens only when I'm logging through with Firefox, what is the reason for that and how can I make this session working in Firefox?

    <?php
    session_start();

    $username=$_SESSION["username"];

    $sql="select * from person where username ='".$username."'";

Answer 1

Your problem seems related to Cache.

Use below headers to remove cache issue. add it after session_start() .

header("Cache-Control: no-cache");
header("Pragma: no-cache");

Hope it will help you :-)
