redirect if url doesn't match parameter

Question

I have a website incorrectly indexed on Google, like this: www.mysite.fr/de-DE/mypage

I need to fix it, with a 301 redirect to www.mysite.de/de-DE/mypage To put it simple, the first level domain (.it, .de, fr...) should correspond to the second url parameter (it-IT, de-DE, fr-FR...). How can I do it using .htaccess only?

Answer 1

You can use this code in your DOCUMENT_ROOT/.htaccess file:

RewriteEngine On

RewriteCond %{REQUEST_URI}::%{HTTP_HOST} ^/([a-z]{2})-.*?::(?:www\.)?mysite\.\1$ [NC]
RewriteRule . http://www.mysite.%1%{REQUEST_URI} [R=302,L,NE]
