It's a good idea to at open graph parameters to the comment page, especially og:url and also parse it with: https://developers.facebook.com/tools/debug/
What I naturally do is: Use the https://apps.facebook.com/canvas_name/url as the href parameter, as it's already a facebook app You can use this, and redirect the user with JS - if it's needed etc. I tested my canvas url, that wraps the .appspot.com url, there were no comment issues I didn't think of it, but the debugger might even tell you if the url is blacklisted: https://developers.facebook.com/tools/debug/ -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
