Enabling auto-discovery for remote trackback pings

If auto-discovery for remote trackback pings is enabled when you post an entry, the system automatically searches your post for links to other blog entries. If any links are found, the system searches for each link's trackback URL and "pings" it; that is, it sends a message to that URL containing information about your blog and entry. Notifications are sent every 15 minutes.

The destination blog page must contain the trackback information in RDF format. If it is not in RDF format, the system will not retrieve a trackback.

Articles are searched for links only once, when they are posted. If an article is edited, it is not re-examined unless the changes include adding a new link. If the system receives a 404 error when pinging a URL, or if the URL does not use the trackback RDF format, the system will not try again.

If pinging is unsuccessful, the trackback will not be listed in the Trackback URLs to notify window.
