How to clear Facebook Sharer cache?

Question

We used the link:

http://www.facebook.com/sharer.php?u=[shared URL]

...to share a particular page. However, Facebook Sharer uses the cache

Answer 1

Facebook treats each url as unique and caches the page based on that url, so if you want to share the latest url the simplest solution is to add a query string with the url being shared. In simple words just add ?v=1 at the end of the url. Any number can be used in place of 1.
