TYPO3 Core

In felogin, if I want after login, go back to referrer page, file `typo3/sysext/felogin/pi1/class.tx_felogin_pi1.php` to get the referrer page, call to `validateRedirectUrl` method, which to validate, needs that the url to be relative, be in current domain, or be in sys_domain table.

That's perfect, but since referrer is not relative, and the login page is in the current domain, it should use second case, but if login page is SSL (with https), and referer, as I'm not logged yet (is http), seems to be different for Typo3. Returning an empty return url.
