Facebook authentication

I have an application which displays canvas page, even though the user clicks "Dont allow" button in a request dialog. Here is my issue:

  1. Load the page http://174.123.24.242/fb_leagle/fbhome.aspx
  2. Login my application through facebook login page of my application.
  3. Click on "Dont Allow" button in a request permission dialog.

In issue #3, if he clicks "Dont Allow" button it will also display the canvas page, and when I click the "BACK BUTTON" of the browser the next dialog appears. Actually I need to skip the canvas page from displaying when user clicks "Don't Allow" button and redirects to the next dialog.

This is my login URL of my application: pls review it and guide me where i need to change it.

According to the OAuth Dialog Documentation, the user will be redirected to the original app-page.

If the user clicks "Don't Allow", the browser will redirect to

http://www.example.com/response?error=access_denied&
error_description=The+user+denied+your+request.

I suggest you use the $_GET['error'] variable to recognize users that denied the request! The different errors can be found here
