Question

Let me explain the situation before I ask the question. I have a site, domain.com. the page sub.domain.com requires a user to be logged in to access. If I allow access to sub.domain.com/login which provides a form whose action is domain.com/login, it sends the data to domain.com/login and redirects back to sub.domain.com/login like it should. However, if I try to access sub.domain.com (which requires authentication) it redirects to domain.com/login correctly, but doesn’t redirect back to sub.domain.com after logging in. I found the error to be that the redirect when not logged in wasn’t sending the referrer header. Is there a way to make it so that if a user tries to access a page on a subdomain that requires authentication, that it will redirect him to domain.com/login, then back to where he originally was?

Ok, it all had to do with routes. I finally was able to get it working by setting up a switch statement in my routes.php file:

switch(Configure::read('subdomain'))
{
     case 'subdomain':
          Router::connect('/login', array('controller'=>'users', 'action'=>'login'));
}

And set up my bootstrap like so:

preg_match('/^(?:www\.)?(?:(.+)\.)?(.+\..+)$/i', env('HTTP_HOST'), $matches); 
$subdomain = empty($matches[1]) ? false : $matches[1];  
if( strlen($subdomain) > 0 && $subdomain != "www" ) 
{
    if($subdomain == 'api')
        $_GET["url"] =  $subdomain . "/" . (isset($_GET["url"]) ? $_GET["url"] : ""); 
    Configure::write('subdomain', $subdomain);
}
