Facebook-share

When you share a link on facebook, Facebook Crawler fetches Open Graph markup data from the link you shared and displays the opengraph data.

Facebook caches this opengraph information for any link shared on facebook. So if any changes has been made to the page, we need to clear opengraph cache so facebook will fetch new opengraph meta data.

Facebook Sharing Batch Invalidator:

Facebook has released a new tool Facebook Sharing Batch Invalidator for refreshing cache for multiple links at once. The Batch Invalidator will let you refresh opengraph information for multiple URLs at the same time.
