For extra points, use wp_redirect:

http://codex.wordpress.org/Function_Reference/wp_redirect

It works on IIS and Apache, and also with different PHP setups that a 
regular header() call won't.

It's also more secure, the URLs are sanitized and run through KSES to 
disallow header splitting attacks.
