<?php /** * 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, and * admin URLs. Does not redirect on non-pretty-permalink-supporting IIS 7+, * page/post previews, WP admin, Trackbacks, robots.txt, favicon.ico, 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 * * @global WP_Rewrite $wp_rewrite WordPress rewrite component. * @global bool $is_IIS * @global WP_Query $wp_query WordPress Query object. * @global wpdb $wpdb WordPress database abstraction object. * @global WP $wp Current WordPress environment instance. * * @param string $requested_url Optional.
