wordpress folder / slug redirect

how do I redirect a category or开发者_JAVA百科 page /my-page/ to a new page /my-new-page/ using htaccess?

Add this above the existing rules (but after RewriteEngine On):

RewriteRule ^/?my\-page /my-new-page [R=301,L]

This works: Redirect 301 /my-page/ http://mydomain.com/my-new-page/
