Tech A quick 'sessions' question

[Publisher Bucks]

Can sessions be carried across multiple domains or are they specific to just one?

I'm using the following on one of our admin systems right now and wondered if it was a good idea to have the same session carried across to our others for staff members that have access to multiple systems?

<?php
// Initialize session
session_start();

// Check if the user is logged in, if not then redirect him to login page
if(!isset($_SESSION["loggedin"]) || $_SESSION["loggedin"] !== true){
header("location: index.php");
exit;
}
?>

If they are able to be used on multiple domains, will the code above be enough or do I need to change that to something else?

Are there any possible issues with using one session across several domains?

TIA for any information you can offer

Sessions are tied to cookies so no, you cannot access them across multiple domains.

You could pass them in the url or something but that would not really be a good thing to do security wise in my opinion.


Again, google is your friend:

My search was "php sessions across multiple domains"

First item was:
