= rack-facebook-signed-request Rack middleware which parses and verifies the signed_request canvas parameter and FB JS cookie. See: http://developers.facebook.com/docs/authentication/canvas Required Options: You must specify the following options to enable the middleware: - app_id - secret Additional Custom Options: You can also activate the following options: - inject_facebook (default false): This will automatically inject the asynchronous FB JS SDK include into the response body. Assuming you've enabled the Facebook script injection, you can customize these options: - cookie (default true): Configure the FB JS SDK with cookie support - status (default true) - lang (default 'en_US') - xfbml (default true) Note that this will also add the FB XML namespace attribute into the root html element of the response. RESTful behavior: The Rack middleware will also convert any POST requests containing the signed_request parameter to GET.
