This is related to another question that I had asked Is fb:multi-friend-selector deprecated?.
One suggestion was to use Request Dialogs (http://developers.facebook.com/docs/reference/dialogs/requests/)
I was reading thru the documentation for Requests Dialog and it has this "If a user clicks 'Accept' on a request, they will be sent to the canvas URL of the application that sent the request".
I want the user to be redirected to my website and not the canvas page. Is this possible? This is possible currently (using xfbml) by using <fb:req-choice url="mywebsite"/>. Will xfbml (using request form and req-choice within it) stop working after June?
You can have a redirect on your canvas url to your website.
