Reverse-proxy issues

[HugoTH85]

Hello,

I have some trouble with trying to use reverse-proxy with OpenNetAdmin. It seems like I cannot use this software like that.
More precisely, when I am using the reverse-proxy URL, I can't connect with a LDAP account, and admin account doesn't have any permissions. Moreover, I cannot see the data (VLAN_campus, VLAN, subnets, etc.).
It would come from the Response Cookie that the server formulates.
To me, it is linked with this lines :

if(PHP_VERSION_ID < 70300) {
      session_set_cookie_params($conf['cookie_life'], '/; samesite=Strict', NULL, $secure, true);
    } else {
      session_set_cookie_params([
        'lifetime' => $conf['cookie_life'],
        'path' => '/',
        'domain' => $_SERVER['SERVER_NAME'],
        'secure' => $secure,
        'httponly' => true,
        'samesite' => 'Strict'
      ]);
    }

in the ona/www/include/functions_general.inc.php file.

What are your opinions about that ?

I have found the origin of this issue. It is directly linked with session parameters which are set up in the functions_general.inc.php file. (path : ./ona/www/include/functions_general.inc.php).
Here is the original part of the code I have modified (line 1260) :

if(PHP_VERSION_ID < 70300) {
      session_set_cookie_params($conf['cookie_life'], '/; samesite=Strict', NULL, $secure, true);
    } else {
      session_set_cookie_params([
        'lifetime' => $conf['cookie_life'],
        'path' => '/',
        'domain' => $_SERVER['SERVER_NAME'],
        'secure' => $secure,
        'httponly' => true,
        'samesite' => 'Strict'
      ]);
    }

You are using the $_SERVER['SERVER_NAME'] superglobal variable and it always returns the server URL even if you're requesting from the reverse-proxy URL. So I have remplaced it with $_SERVER['HTTP_HOST'] that returns the domain name that appears in the HTTP Request Header and now it works pretty well !
So here is the modified part of the code :

if(PHP_VERSION_ID < 70300) {
      session_set_cookie_params($conf['cookie_life'], '/; samesite=Strict', NULL, $secure, true);
    } else {
      session_set_cookie_params([
        'lifetime' => $conf['cookie_life'],
        'path' => '/',
        'domain' => $_SERVER['HTTP_HOST'],
        'secure' => $secure,
        'httponly' => true,
        'samesite' => 'Strict'
      ]);
    }
