Largely inspired by Otto's suggestions, I attempted to make an AJAX
interface that would work on the front end using template_redirect. In
my testing with WP 2.8.6, I found that POST requests done this way
would get a 301 response, which would redirect to a GET on the same
URL (of course now without the POST data). Anyone know of core code
that might do that?
