Pingback

Pingback is a means for web authors to request notification when somebody links to one of their documents. Typically, web publishing software automatically informs the relevant parties on behalf of the user, making it possible to automatically create links to referring documents.

For example:

1. Alice writes an interesting article in her blog.

2. Bob reads the article writes about it on his blog and links back to Alice’s original post.

3. Bob’s blogging software uses pingback to automatically notify Alice that her post has been linked to.

4. Alice’s blogging software includes this information on her site.

Forum provides a web application called pingback, which listens for pings, verifies them and stores them as as special type of posting.
