/** * Canonical API to handle WordPress Redirecting * * Based on "Permalink Redirect" from Scott Yang and "Enforce www.

Does not redirect on non-pretty-permalink-supporting IIS 7+, * page/post previews, WP admin, Trackbacks, robots.txt, searches, or on POST * requests. * * Will also attempt to find the correct link when a user enters a URL that does * not exist based on exact WordPress query.
