No caption property for Facebook Open Graph
So, basically because I'm on a mobile phone, I can't use www.facebook.com/sharer.php. I need to use Open Graph meta tags on my page and share that page using m.facebook.com/sharer.php. The problem I'm currently running into is that it is not possible to specify the title of this resource using public meta tags. It continues to use the domain of the URL. With web chat, you can provide a title and it will put it under the title.
Does anyone know how I can specify the share header in the Open graph using meta tags? There seems to be no meta tag that matches the web chat header query string parameter.

The endpoints are sharer.php
officially out of date for a while. You shouldn't develop new code that relies on them, as they can stop working at any time.
Instead, use the feed dialog . This gives you the ability to customize your custom signature.
