Hey all,
I found a big bug in trackback. Despite all of my testing and
retesting, I somehow completely missed the fact that it's only
accepting pings when the other site is pointing directly at the
message page. (So it won't work if they're linking to the fullthread
page, or the weblog II page, or Bound URL pages, etc.)
I know how to fix it, but it's going to require a change to the
trackback url and the trackback:ping portion of the autodiscovery
template.
This is a little ridiculous, and I apologize. It's also rather
complicated, and now I understand why most systems which support
trackback don't bother with any security features.
It'll be fixed this weekend. Thanks for your patience.
Seth
