Facebook Like button cache
Posted on 2011-10-21
When you click a Like button it seems to copy what's between the Title tags, some meta words and the first image it finds to your Facebook page. But it seems to cache this information because if I change it on the website page and unlike/relike the page, the old information gets transferred again to Facebook. Is there a way to clear this cache so new data is copied?
Also, is it documented somewhere exactly what is copied to Facebook. It's not clear what meta words are taken.
Thanks for any help,
