All subdomains redirect to one subdomain

Server Config

Need to redirect the all sub-domains, except en.domain.com
to en.domain.com

Like
www.domain.com/en/ -> en.domain.com
www.domain.com/en/test -> en.domain.com/test
www.domain.com/en/dir/index.htm -> en.domain.com/dir/index.htm

domain.com/en/ -> en.domain.com
domain.com/en/test -> en.domain.com/test
domain.com/en/dir/index.htm -> en.domain.com/dir/index.htm

What is wrong with the following code?

RewriteEngine on
RewriteCond %{HTTP_HOST} !^en.* [NC]
RewriteRule ^/en/(.*) http://en.domain.net/$1 [L,R]

pedro,

This code will redirect www’d domains to en.domain.net, too!

Worse:

  1. You should escape the dot in the RewriteCond and then NOT include the * metacharacter as that causes this to match encyclopedia.whatever. That’s NOT your intention (at least I hope it’s not).

  2. In an .htaccess file, ^/whatever will only be matched by an Apache 1.x server. If you’re using Apache 2.x, drop the /; if you’re not sure, use ^/?.

  3. R’s default is 302 (temporary) so, if you want SE’s to update, change that to R=301.

Where is the document for the en subdomain? If it’s the en subdirectory, that means that you’re set but, if not, then you’ve got some more work to do.

Regards,
