3 * Canonical API to handle WordPress Redirecting
5 * Based on "Permalink Redirect" from Scott Yang and "Enforce www. Preference"
13 * Redirects incoming links to the proper URL based on the site url.
15 * Search engines consider www.somedomain.com and somedomain.com to be two
16 * different URLs when they both go to the same location. This SEO enhancement
17 * prevents penalty for duplicate content by redirecting all incoming links to
20 * Prevents redirection for feeds, trackbacks, searches, comment popup, and
21 * admin URLs. Does not redirect on IIS, page/post previews, and on form data.
23 * Will also attempt to find the correct link when a user enters a URL that does
24 * not exist based on exact WordPress query. Will instead try to parse the URL
25 * or query in an attempt to figure the correct page to go to.
31 * @param string $requested_url Optional. The URL that was requested, used to
32 * figure if redirect is needed.
33 * @param bool $do_redirect Optional. Redirect to the new URL.
34 * @return null|false|string Null, if redirect not needed. False, if redirect
35 * not needed or the string of the URL
