Need to authenticate an user and redirect him to the requested page: possible?

[eluser]Ki[/eluser]
What about passing the resource link in the url to the controller that handles authentication and then redirect to that url. You can pass it as /login/redirect/new/url/to/redirect/to/
Then, once authentication complete, extract everything after /redirect/ and do a redirect() to it.
Is that something you are looking for?
