Refreshing FBML Caches

Problem

I need to tell Facebook to refresh its caches for some of my stored data.

Solution

If you’re caching images, use the FBML.refreshImgSrc() method:

$return = $facebook->api_client->fbml_refreshImgSrc
('http://www.someserver.com/images/some_image.jpg');

If you’re caching URLs, use the FBML.refreshRefUrl() method:

$return = $facebook->api_client->fbml_refreshRefUrl
('http://www.someserver.com/page.php');

Discussion

This returns true (1) if Facebook is able to locate an entry in its cache with the url you passed in and can refresh, or false (0) or blank if it can’t.
