How to redirect all pages in the subdomain except a few?

Question

I am working on a subdomain where I need to redirect all pages to the main domain except a few pages.

For example, http://subdomain.domain.com/contact-us and http://subdomain.domain.com/thank-you pages should not redirect. All other pages should be redirected to http://www.domain.com .

The main domain is hosted elsewhere and the subdomain is pointed to the server I have access to. In the subdomain's .htaccess, can I have something like this: RewriteEngine On RewriteBase /

RewriteCond %{HTTP_HOST} !^www\.domain\.com
RewriteRule ^(.*)/?!(contact-us|thank-you)$ http://www.domain.com/$1 [R=301,L]

Answer 1

You were close:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.domain\.com
RewriteRule ^(?!(?:contact-us|thank-you))(.*)/?$ http://www.domain.com/$1 [R=301,L,NE]

The negative lookahead (?!(?:contact-us|thank-you)) ensures that what follows is neither contact-us nor thank-you .
