redirecting after facebook app request

Question

I am sure it is a simple question but I am not familiar to the Facebook api. I have a Facebook app, and I send some app request

FB.ui({method: 'apprequests',
                             message: 'Would you join me ?' + ' ' + url,
                             to: $some_id
                             });

The app request is correctly sent but when when the invited user clicks on his Facebook space notification, he is not redirected to the url but instead in some https://apps.facebook.com/myapp/.... url which crashes. It seems to be my canvas page but what am I suppose to do with this url, how do I put code to redirect the user ?

Answer 1

App requests should only be used for Canvas applications - the notifications will always link to the Canvas URL for your application. You can simply point the Canvas URL to a page within your app to redirect the user elsewhere, but it's not permitted by Facebook Policies.

As the Platform Policy states:

Don't build an app whose primary purpose is to redirect people off of Facebook.
