/**
* Canonical API to handle WordPress Redirecting
*
* Based on "Permalink Redirect" from Scott Yang and "Enforce www. Preference"
* by Mark Jaquith
*
* @package WordPress
* @since 2.3.0
*/
/**
* Redirects incoming links to the proper URL based on the site url.
*
* Search engines consider www.somedomain.com and somedomain.com to be two
* different URLs when they both go to the same location. This SEO enhancement
* prevents penalty for duplicate content by redirecting all incoming links to
* one or the other.
*
* Prevents redirection for feeds, trackbacks, searches, comment popup, and
* admin URLs. 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. Will instead try to parse the URL
* or query in an attempt to figure the correct page to go to.
*
* @since 2.3.0
* @uses $wp_rewrite
* @uses $is_IIS
*
* @param string $requested_url Optional. The URL that was requested, used to
* figure if redirect is needed.
* @param bool $do_redirect Optional. Redirect to the new URL.
* @return null|false|string Null, if redirect not needed. False, if redirect
* not needed or the string of the URL
