mod_rewrite problems - redirect subdomain to different domain

Question

I must have a brain freeze as I can not get my rewrite rules working.

RewriteEngine On

RewriteCond %{HTTP_HOST} ^otherdomain\.example\.com [NC]
RewriteRule ^(.*) http://www.otherdomain.com/ [R=permanent,L]

RewriteCond %{HTTP_HOST} ^(www\.)?example\.com [NC]
RewriteCond %{REQUEST_URI} ^/otherdomain [NC]
RewriteRule ^(.*) http://www.otherdomain.com/ [R=permanent,L]

What I want is essential to redirect

otherdomain.example.com and example.com/otherdomain to otherdomain.com

Answer 1

Just use the below redirection. will work 100%. Because I personally use it for my website....

RewriteCond %{HTTP_HOST} ^subname\.old-main-domain\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.subname\.old-main-domain\.com$
RewriteRule ^(.*)$ "http\:\/\/www\.newdomain\.com\/$1" [R=301,L]
