I have an old domain that I'm retiring. How do I set up a permanent redirect from the old domain to the new one?

Question

I originally posted this as one of the defining questions for the site so I thought I'd ask it again.

Currently I have DNS for both domains pointing to the same place but I'd like to set up a permanent redirect from the old one to the new one for any lingering links out in the wild.

This page lists how to do it using common web languages. Note the section entitled "Redirect Old domain to New domain"

Also, Google has provided a nice article on what to consider when moving your site.
