How to redirect everything ending with .htm?

Question

In short, I want all pages ending with .htm to redirect to one single page.

I have a newsarchive with a lot of news articles. They all end with .htm so I want all urls ending with .htm to redirect to one single page

How do I do this?

Answer 1

You can use RedirectMatch rule:

RedirectMatch 302 \.html$ /single-page

EDIT: Fixed typo in RedirectMatch
