The CORS scheme is:
AJAX Call from: https://remotewebsite.com/
GET Request to http://localhost/?param=ThisIsImportant
I am using localhost because it still in development.
Request URL: http://localhost/?param=ThisIsImportant
Request Method: GET
Status Code: 200 OK

Server: Apache/2.4.48 (Win64) OpenSSL/1.1.1k PHP/8.0.8

X-Powered-By: PHP/8.0.8
PHP Pseudo-code
session_start();
$_SESSION['hash'] = $_GET['param'];
If I enter in http://localhost and visit a script with:
session_start();
print_r($_SESSION);
Session is empty. If I check cookies in developer tools, PHPSESSID is different from the one on AJAX response.
I need set the PHPSESSID during AJAX response and kept, and be able to retrieve the SESSION['hash'] set on PHP during that AJAX request. Including in another scripts on localhost. Is that possible?
Found that the $.ajax request should contain
withCredentials: true
crossDomain: true
on server-side, the script need:
header('Access-Control-Allow-Credentials: true');
session_set_cookie_params(["SameSite" => "none"]); //none, lax, strict
session_set_cookie_params(["Secure" => "true"]); //false, true
session_set_cookie_params(["HttpOnly" => "true"]); //false, true
that's it.
