Chapter 8: TrackBack
Enabling Auto-Discovery of TrackBack Resources
Problem
You don't want to be bothered figuring out which links in your entry are TrackBack-enabled.
Solution
Use the TrackBack Auto-Discovery option on the New Entry Defaults tab of the Settings Screen.
Discussion
TrackBack clients need a method of determining the TrackBack Ping URL
for a particular URL. If a resource is courteous, they will have embedded
the information necessary to make a TrackBack ping. (This is the same
information that the MTEntryTrackBackData will insert into a
template.) This information allows the TrackBack client to auto-discover
the TrackBack Ping URL and send the ping without further data entry or
intervention from the user.
To enable TrackBack Auto-Discovery, click Settings on the Weblog Toolbar and go to the New Entry Defaults tab. Check the TrackBAck Auto-Discovery option under the Publicity/Remote Interfaces section.
