I've written a spec for <meta name="referrer"> and moved the registration the "Proposals that don't meet the requirements for a registration" to the "Registered Extensions" section of http://wiki.whatwg.org/wiki/MetaExtensions. Let me know if you have any feedback: http://wiki.whatwg.org/wiki/Meta_referrer Please find below the use cases and examples from the spec. (Details are, of course, in the spec itself.) Thanks! Adam = Use Cases = An author might wish to control the Referer header omitted by a document for a number of reasons. == Privacy == A social networking site has a profile page for each of its users, and users add hyperlinks from their profile page to their favorite bands. The social networking site might not wish to leak the user's profile URL to the band web sites when other users follow those hyperlinks (because the profile URLs might reveal the identity of the owner of the profile). Some social networking sites, however, might wish to inform the band web sites that the links originated from the social networking site but not reveal which specific user's profile contained the links. == Security == A web application uses HTTPS and a URL-based session identifier. The web application might wish to link to HTTPS resources on other web sites without leaking the user's session identifier in the URL. == Trackback == A blog hosted over HTTPS might wish to link to a blog hosted over HTTP and receive trackback links. = Examples = This meta element instructs the user agent to omit the Referer header in all HTTP requests that originate from the document containing the element: <meta name="referrer" content="never"> This meta element instructs the user agent to include the document's origin in the Referer header rather than the full URL of the document: <meta name="referrer" content="origin"> Note: The user agent will include the origin string in the Referer header even for links from HTTPS to HTTP resources.
