How do I force facebook to re-parse my shared URL after it caches it?

Facebook will normally parse and cache the shared URL for some time. In order to clear facebook cache and tell it to re-parse the URL do the following.

1. Login to facebook
2. Go to Facebook Sharing Debugger, found at: https://developers.facebook.com/tools/debug/sharing
3. Paste URL and click “Debug” button
4. Click on “Scrape Again” button to refresh the facebook cache
