|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, searches, or on POST
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.
