title: Using WIF with asp.net MVC 3, where do I define the STS Sign out endpoint?
body: <p>I see that the FedMetadata document can provide signout notification and subscription endpoints, and web.config defines the issuer url for sign in requests, but I can't find where WIF knows to send sign out requests. If the STS I'm using defines different endpoints for sign in and sign out requests, how could I access that in code or set that up in web.config?</p>
