* Redirects incoming links to the proper URL based on the site url. |
|
14 |
* |
|
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 |
|
18 |
* one or the other. |

* Prevents redirection for feeds, trackbacks, searches, and |
| 0 | 21 |
* admin URLs. Does not redirect on non-pretty-permalink-supporting IIS 7+, |
| 16 | 22 |
* page/post previews, WP admin, Trackbacks, robots.txt, favicon.ico, searches, |
23 |
* or on POST requests. |
|

* Will also attempt to find the correct link when a user enters a URL that does |
|
26 |
* not exist based on exact WordPress query. Will instead try to parse the URL |
|
27 |
* or query in an attempt to figure the correct page to go to. |
