I like the idea -- thinking out loud here, rather than invoking it when all pages having the same logout="" attribute are closed, can it instead use some other grouping identifier? That would allow a developer to pass back unique information from each page via the URI. And I like POST instead of GET. A same-origin restriction would be good too. Would the browser accept a response from the logout? I'm thinking that could be used to immediate end the cookie(s).
