I recently created a post with trackback, using the bookmarklet.  It worked fine, but I then edited the post several times to try to fix a weird link problem.  When I went back to the other guy's blog, I found that his trackback page had a link for each time I saved my post -- even for the times that I removed the link from the "URL's to Ping" box.

So, is there a way I can edit a post without sending another ping and creating multiple trackback entries?  Even better, is it possible to send some sort of 'update' ping that would update the text of my trackback entry on the other blog?  Thanks.

It would help if the trackback receiver understood that your subsequent ping isn't 'different' enough for it to bother adding another one.

But as for editing your current pings, that introduces the problems of authentication.  Right now pings are (largely) anonymous.  So it has no real way of know that you are who you say you are when you come back to 'edit' the ping at a later time.

Thus why I've inquired about making better use of pgp for handling such things...

Yeah, I can see where authentication on a trackback update would be a problem.  PGP could work, but it might be overkill.  I could see the 'pinging' end just creating a random string of, say, 32 characters, and sending that as part of the initial ping while storing it.  Then any update ping would have to match that same string.  Beatable by a brute-force attack, but unlikely.

So I guess I'm back to the first question:  Is it possible to edit a trackback-created post without re-pinging the original?  If not, that really hurts its usefulness for me, since I often think of something I want to add or fix.

The problem of sending multiple pings doesn't strike me so much as one of authentication -- after all, I don't want to modify a past ping, I just don't want to send another one. After inadvertently sending multiple pings in the last couple of days, I'd just like to see MT refrain from pinging the same remote url more than once from a given entry.

As a persistent repeat pinger, I'm intensely interested in any suggestions anyone might have. Here's another thread with more information on why duplicate pings happen; good info, but no suggestion on how to stop them, really.

There was a method floating around for previous versions of MT, but it's been lost to the ether of the Internet and might not work with the latest MT versions anyway.

A little help? Even a way to search the Google cache?
