Htaccess and 301 redirects (solved)

Hi guys,

I changed my blog articles

Because I have some campaigns with the old url, I want to create a htaccess rule to redirect to the new url. I could do it article by article, but there are many articles. I would prefer a rule to get it done, if there was one.

Could anybody help me with this issue?

I answer myself:

<IfModule mod_rewrite.c> 
RewriteEngine On 
Redirect 301 /articles/article/ /article/


I found this site to generate htaccess redirects:
