Homebrew TrackBack Tutorial
Homebrew TrackBack Tutorial. Since I couldn’t find any documentation on how TrackBack works, I threw together this quick tutorial on the basic steps involved in sending and receiving TrackBack pings.
I’m also trying to come up with a way to use TrackBack with my project pages (and not just individual blog entries).
Matt, great write up. I had a few comments.
– I was wondering what the limits were for the excerpt. Is the URL limited to sending something like 255 characters of information? I’m trying to determine how much of an excerpt I can safely send out.
– How do you handle duplicate pings? Look up the same root URL for the same ID? Should duplicate pings replace originals (as someone might be fixing their tb system), or should they be ignored?
– I kind of like the way I handle people hitting the trackback url in their browser over an xml error message. If the tb script loads without additional URL data, I present a page explaining the system. Because it’s a link at the end of each new post at metafilter, I figured showing human friendly pages would be a better way to go than xml dumps.
