.htacess rewrite help please.

I'm using a rewrite to direct whole root domain to another domain.

Though I use some rules to stop a subdomain from being redirected also.

One problem I'm having is setting this to stop 2 subdomains from redirecting rather than just one. Here is the code I'm using.

Code:

---

Options +FollowSymLinks
RewriteEngine on

# Stop pro
rewriteCond %{HTTP_HOST} ^forum\.mydomain.com$
rewriteRule .* - [L]

#skip if

rewriteCond %{HTTP_HOST} ^forum\.mydomain.com$
rewriteRule .* - [S=2]

#continue pro
RewriteCond %{HTTP_HOST} ^www.mydomain.com$
RewriteRule ^(.*)$ "http\:\/\/www\.my new domain\.com\/$1" [R=301,nc]

---

What do I need to add to stop another 2 subdomains redirecting called themes.mydomain.com & wp.mydomain.com?

Thanks all.

Anyone have any ideas please?

I know it's prob something simple but unfortunately I'm clueless :-(

Thanks
