The Shorter Links WordPress plugin automatically creates a link element in the section of the post's page with a rel="shorturl" attribute. The URL in the href attribute defaults to the id number of the post in question. It also creates an HTTP Link header that also points to the shorter link.

A custom field called "Shorter link" is created once a post is saved, so that you can change the shorter link to a more memorable set of characters.

The choice of base URL to use for the short link can be configured within Settings->Shorter Links.

The <link> element looks like this:

<link rel="shorturl" href="{url}" />

The HTTP header is:

Link: <{url}>; rel=shorturl
