Redirect an old URL to the new one with htaccess

[egoicantero]

I need to redirect viewers that enter my website from an old URL to the new one. I am trying to do it via htaccess, but I haven’t found the key yet.

The olf url is:

www.anykindofwebsite.org/contact/

And I want it to be redirected to:

www.anykindofwebsite.org/en/contact/

I am trying with the following code with no result:

RedirectMatch 301 ^contacto/$ es/contacto/

@egoicantero: do you just want to redirect a single URL? If so, this should work:

Redirect 301 /contact/ /en/contact/
