I am trying to figure out the best way to implement trackbacks.

Obviously, I am sure people do NOT create a new file in a folder for each blog entry. Everything is database driven so I would assume that URL rewriting is used to give that effect.

However, even if URLs are rewritten, can you POST and GET at the same time? (The rewritten URL uses 'GET' to specify the blog ID and then receive a 'POST' which is the trackback ping.) Even if that does work, the host I am on does not (as far as I know) have any method for me to rewrite my URLs.

How would you implement trackbacks?

I found out I can rewrite my URLs! =) Trackbacks on it's way!
