How to refresh the cached title of a page Liked on Facebook?

I have a couple of embedded YouTube videos which I have added Like buttons for. The titles were wrong the first time I tested the Like functionality.

Although the 开发者_StackOverflowvideo titles have now been changed, the old titles are still showing up in a user's news feed when they click Like.

Is there a way to get Facebook to get the new titles of the page, or are the titles now cached forever?

You can use Facebook URL Debugger to refresh the data. This tool is ment for debugging open graph tags on webpages. It has nice side effect of updating Facebook cache of the debugged URL. Originally this tool was named Facebook URL Linter.
