Redirect from one domain to another

[JohnKelly]

I know this is an extremely common question, and I've done my search and come up with code. What I want to do is have any request for [images.olddomain.com...] to alias to [images.newdomain.com...]

Is it possible to do this without a browser or search engine "knowing" they're at images.newdomain.com (i.e. file displayed is from images.newdomain.com but URL bar still shows images.olddomain.com)?

Here is the code I have which I've seen used on many searches, yet doessn't work. Do I need to have images.olddomain.com setup or not?

Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^images.olddomain.com$ [NC]
RewriteRule ^(.*)$ [images.newdomain.com...] [R=301,L]

Code was messed up:

Options +FollowSymLinks 
RewriteEngine on
RewriteCond %{HTTP_HOST} ^images.olddomain.com$ [NC]
RewriteRule ^(.*)$ http://images.newdomain.com/$1 [R=301,L]

The above code is for a redirect. A redirect forces the browser to make a new request for a new URL.

Use example.com to stop the forum reformatting your code.

If both domains are on the same server, you might use an internal rewrite instead of an external redirect.

If they are on different servers, use a Proxy but be aware that will slow the site down and will mess up the logging and analytics.
