    Displays the minilogin page in an iframe, but only if the user

    This could have been done using an iframe coded into the page
    that would be hidden if the user is logged in, but that would 
    degrade response time, since the request would be made anyway.
    
    Many sites just place the login form on the unprotected page, 
    but that's not secure.
