Authentication within introspection

<introspection>

  <authentication>
    <login url="http://foo.bar/?action=login-neutron">
      <message>Login for realm 'Foo Bar' ...</message>
      <form>
        <param description="Username" name="username"/>
        <param description="Password" name="passwd"/>
      </form>
    </login>
    <logout url="http://foo.bar/?action=logout"/>
  </authentication>

</introspection>

Questions:

• What happens after the login?
• Does the user has to reload the page then in order to get extended introspection data?
