My system based like that:
Whenever I change the article name, the url changes to:
In addition, I can access the article no matter what the name is, like that:
It will enter the same article as above.
My problem: I'm trying to do: 301 redirection to all pages that are NOT the original url(the real name of the article) and the article will be accessible only in one, original url - even after I change the article name it will redirect the old url to the new one (301 redircetion).
How I can do that?
