I'm having trouble keeping the user on the page he starts on. If he starts on a page where there is a comment form but he needs to log in first. After clicking the facebook link he get's logged in and then redirected to the callback page.
I have tried to set the 'REQUEST_URI' in a SESSION variable on the original page but it seems that my session is getting wiped out in the login process. Is there another way to track where the user needs to go back to?
