cotonti.com : auto-logged out if using url_rewrite and not checking "remember me" box https://www.cotonti.com Son konu mesajları Cotonti en Sat, 18 Oct 2025 19:37:49 -0000 Trustmaster Per, 01 Tem 2010 15:10:23 -0000 donP
P.S. Do you suggest me to use a random-value-generator function? Do you know some?
P.S.2 I'd remember you that many other parts of Cotonti Code have to be changed in my case (using mod_rewrite to create subdomauins)... all SED_ABSOLUTE_ULR codes at first...

I've tried, following your suggestions...

I first used

$site_id = 'ct' . sed_unique(16);

but I couldn't login at all, no more.

Then I tried

$site_id = 'alphanumericalstring';

and the problem was the same I described in the first post of this topic... so, it would be the PHPSESSID cookie and its domain (but I can't figure how it can function now simply by permanently checking the "remember me" checkbox... but it work well, and I use this solution for now).]]> Pzt, 07 Haz 2010 15:45:05 -0000 Trustmaster 
$site_id = 'ctSomeRandomThingHere';
In Siena it will be possible to set site_id in config.php with $cfg['site_id'] for sites with subdomains.

Have you tried this solution? If it doesn't work then I think the reason might be PHPSESSID cookie and its domain.]]> Cum, 04 Haz 2010 13:51:14 -0000 donP In fact, everytime I surfed from www.mydomain.net to one of the subdomains I got logged-out (and when I returned to the same location but with normal ulr (e.g. www.mydomain.net/list.php?c=cat1) I was magically still logged-in.

I think I've found the problem...

In system/common.php we have:

$site_id = 'ct' . substr(md5($cfg['mainurl']), 0, 10);
$sys['site_id'] = $site_id;

session_start();

if(!empty($_COOKIE[$site_id]) || !empty($_SESSION[$site_id]))
{
	$u = empty($_SESSION[$site_id]) ? base64_decode($_COOKIE[$site_id]) : base64_decode($_SESSION[$site_id]);
	$u = explode(':_:', $u);
	$u_id = (int) sed_import($u[0], 'D', 'INT');
	$u_passhash = sed_import($u[1], 'D', 'ALP');
	if($u_id > 0)
	{

As you can clearly see, the value of $sys['site_id'] (used to create log-session-cookie) is derived from $cfg['mainurl']... obviously, a url with a subdomain format doesn't match with this cookie... so, the user is seen as logged-out when we have a subdomain in url but not when we write the corresponding (original) ulr for that location.

For now, the only solution I've found is always checking the "Remember me" checkbox when loggin-in (I don't know how this trick interacts with session-coockie-creation...
I had to core-hack system/header.php changing this line:
$out['guest_cookiettl'] = '<input type="checkbox" name="rremember" />';
like that:
$out['guest_cookiettl'] = '<input type="checkbox" checked="yes" name="rremember" style=" visibility: hidden; " />';
to set always checked that box and not to permit users to un-check...

I hope Developers could find a solution with newer auth_session methods...]]> Cum, 04 Haz 2010 07:16:20 -0000
