I have a perl CGI script doing the Facebook authorization flow as described at http://developers.facebook.com/docs/authentication/. When I go to my Facebook app page in a browser my script receives the initial query from Facebook, authenticates the signed_request, and then sends a redirect to the following url:
https://graph.facebook.com/oauth/authorize?client_id=NNN&scope=[...]&display=page&redirect_uri=http%3A%2F%2Fmydomain.com%3A8080%2Fperl%2Fdev%2Ffb.pl%3Fcallback%3D1
The redirect_uri is what I have defined as my Web Site in the app config, and it gets accepted just fine. But what the browser then shows is a big Facebook logo image and a link below it, both of which go to:
http://www.facebook.com/connect/uiserver.php?display=page&next=https%3A%2F%2Fgraph.facebook.com%2Foauth%2Fauthorize_success%3Fredirect_uri%3D[...]
When I click on that I get what I want, the "Request for Permission" page asking the user to authorize the app. Everything proceeds normally from there.
So why am I getting that initial FB logo page instead of going directly to the authorization page?
