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.
