 an example says more than 1000 words:

 right url:

 http://ahmongwoman.wordpress.com/2010/09/02/i-am-not-hmong-and-i-dont-
 speak-spanish/

 wrong urls:

 http://ahmongwoman.wordpress.com/2010/09/02/i-am-not------hmong-and-i
 -dont-speak-spanish/

 http://ahmongwoman.wordpress.com/2010/09/02/i----am-not-hmong-and-i-dont-
 speak-spanish/

 http://ahmongwoman.wordpress.com/2010/09/02/i-am-not-----hmong-and-i
 -------dont-speak---------spanish/

 Problem:

 Wordpress returns the article with HTTP status code 200 for the wrong
 URLs.

 This is a serious issue for people regarding search engine optimization
 (duplicate content).

 Expected results:

 Wordpress returns HTTP Status code 301 with Location-Header and right URL
 to the client.
