I often use the following .htaccess / mod_rewrite solution to redirect domain names based on the requested domain. The reasons for this are many. Most recent example for me is I had a single site with 5 alias domains but software licensed for only one. Even though I had the alias domains set up on the server it still did not satisfy the license. Add the line below to htaccess and now no matter which of the 5 domains are written in they are re-written to the one with the licence (need to duplicate for each domain). The license is valid since its all the same physical website and everyone is happy. Brilliant!
I am sure there is a more eloquent way of accomplishing this with mod_rewrite - but this gets the job done!
RewriteCond %{HTTP_HOST} ^(www\.)?yourdomain\.com [NC]
RewriteRule ^(.*)$ http://otherdomain.com/$1 [R=301,L]
Can also be used to redirect to a landing page based on the requested domain:
RewriteCond %{HTTP_HOST} ^www.domain.com
Rewriterule ^(.*)$ http://www.any-domain.com/landing-page.html [L]
Have a better solution? I’m no mod_rewrite guru so comments are always welcome!
