Question

I have 2 TLDs example.com and example.ie.

example.com and example.ie both point at the same IP address and pull the same content now we could get whacked with a ban hammer from Google for duplicate content so we want anyone accessing *.example.ie and *.example.com to be redirected to www.example.com the problem is as they are both pointing at the same server the .htaccess is the same thus I don’t believe we can do the usual:

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

So how do we go about creating a search-engine friendly 301 redirect from *.example.ie and *.example.com to www.example.com?

Answer 1

I would do it like this:

RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com$1 [R=301,L]

That will redirect (statuscode 301 “permantly moved”) every domain which is not http://www.example.com to http://www.example.com.
