htaccess: Multiple transformations in a single redirect

Question

I want to do those classical 301 redirects:

• Prepend "www" if there is not.
• Add "/shop/" directory if there is not.
• In both cases, I want to mantain the file requested and possible parameters.

And also (this is the point) I want to avoid multiple redirects when http://myhost.com is requested:

1. 301 -> http://www.myhost.com
2. 301 -> http://www.myhost.com/shop/

I want only 1 redirect. How can I do it in the simplest way?

Answer 1

You can use this :

RewriteEngine on
RewriteCond %{HTTP_HOST} !^www [OR]
RewriteCond %{REQUEST_URI} !^/shop
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$
RewriteRule ^ http://www.%1/shop%{REQUEST_URI} [NE,L,R=301]
