title: cakephp auth redirect and referrer
body: <p>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?</p>
