[wp-hackers] 302 redirect - why?

[Otto]

The reason you have it send a 302 instead of a 301 is that you don't
want the client to change the actual URL it's sending to, if it sent
the wrong thing by mistake.

Say a client tries to send a trackback, but something goes wrong and
it leaves off the URL. You send back a 301. According to standard
methods, the client, if it retries later, should retry at the new
location only. Meaning that the trackback will never get there.

By sending a 302, you account for possible errors.
