I want to create a mobile website with a restricted login page. That is, such that to view the login page, a link with a protection code should first be sent to you via sms or other way. That is something like http://m.mobilesite.(com)/login.php/243948
The link should expire say after 24 hours. And if the user happened to type the link without the protection code, it would be redirected to a parking page.
Any one with an idea how to go about it?
