  // Note : This implements HttpRequestInterceptor rather than extending
  // HttpRequestInterceptorBase, because that class is an auth-specific
  // class and refactoring would kludge too many things that are potentially
  // public api.
  //
  // At the base, though, what we do is a very simple thing to protect
  // against CSRF attacks, and that is to simply add another header. If
  // HS2 is running with an XSRF filter enabled, then it will reject all
  // requests that do not contain this. Thus, we add this in here on the
  // client-side. This simple check prevents random other websites from
  // redirecting a browser that has login credentials from making a
  // request to HS2 on their behalf.
