Facebook comment/like url

Am having difficulty with the url for the facebook comment and like plugins. if I put in a simple url like "www.example.com" it works fine but my app is on a subdomain and uses querystrings to differentiate between different page states. So a sample url would be something like "facebook/example.com/index.php?id=001". However it appears facebook doesn't like this and keeps saying it is unreachable.

I can't bel开发者_开发问答ieve facebook would limit the scope like this. Someone else must have encountered this. Any suggestions?

Facebook posts have an id something like 123456789012345_123456789012345.

The part prior to the underscore is the page id. The part after is the post id. The URL would be https://www.facebook.com/pageid/posts/postid, or https://www.facebook.com/123456789012345/posts/123456789012345.

Check your URL in Facebook's Debug Tool and this will show the tags Facebook is detecting on your page -in particular check your og:url tag isn't ommitting the URL parameters
