Comment 1 for bug 1504691

@Rocky, Thanks for submitting the bug.

Since RefStack is using OpenStackID for user authentication, RefStack sign in/sign up link will direct user to either the OpenStack OpenID log in or verification page depending on whether the user has previously logged in and has a session at the OpenStackID server or not.

As for caching, there are several levels of caching (user's browser, OpenStackID server and RefStack server). We will review RefStack caching control as much as we can to improve user experience. I agree with you that, it is worthwhile to provide as many hints as it is possible to do so.
