It seems the facebook debug tool http://developers.facebook.com/tools/debug is using a cache.
I made an update to my site but facebook debug tool is still showing up the old data.
Is their any way to force facebook to refresh its data? It has been a few days now and it seems the cache will not expire.
The cache access debug allows you to view the cache operations that the system performs for individual web requests (adding items to the cache, loading data from the cache).
The Best Way to Clear Facebook's Open Graph Cache The easiest way to clear out Facebook's open graph cache is to use their debugging tool. Enter your URL of the page, hit 'debug' and then on the next page, hit 'fetch new scrape information' or 'scrape again'.
