.htaccess redirect subdomain to main site - no exeptions!

Question

Hi everyone, I'm trying to redirect all requests for example.domain.com to www.domain.com

Options +FollowSymLinks
RewriteEngine on
RewriteRule (.*) http://www.domain.com/$1 [R=301,L]

Seems to cause a 500 internal server error as does

Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} ^domain.com [nc]
rewriterule ^(.*)$ http://www.domain.com/$1 [r=301,nc] 

So my question is why are these failing and how do I fix it?

Answer 1

After your first two lines, add:

RewriteCond %{http_host} ^.domain.com
RewriteRule ^(.*) http://domain.com/$1 [R=301]
