RSS Autodiscovery
RSS autodiscovery is a technique that makes it possible for browsers and other software to automatically find a site's RSS feed. Autodiscovery informs users that a web site offers a syndication feed. When a browser loads a page and discovers that a feed is available, it displays the common feed icon in the address bar. Users can click the icon to subscribe with the browser's RSS reader or the user's preferred reader. This specification describes how web publishers can support autodiscovery by adding an HTML header to web pages.
