htaccess how to redirect subdirectory to external URL

Question

I tried:

//301 Redirect Old File
Redirect 301 www.mydomain.com/subdirectory http://newurl.com

but that lands me at newurl.com/subdirectory, which doesn't exist.

Solution

Enable mod_rewrite and .htaccess then add this code in your .htaccess under DOCUMENT_ROOT:

Options +FollowSymLinks -MultiViews
# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} ^(www\.)?mydomain\.com$ [NC]
RewriteRule ^subdirectory/?$ http://newurl.com [L,R=301,NC]
