   * Add a cookie. nsICookieService is the normal way to do this. This
   * method is something of a backdoor.
   *
   * @param aHost
   *        the host or domain for which the cookie is set. presence of a
   *        leading dot indicates a domain cookie; otherwise, the cookie
   *        is treated as a non-domain cookie (see RFC2109). The host string
   *        will be normalized to ASCII or ACE; any trailing dot will be
   *        stripped. To be a domain cookie, the host must have at least two
   *        subdomain parts (e.g. '.foo.com', not '.com'), otherwise an
   *        exception will be thrown. An empty string is acceptable
   *        (e.g. file:// URI's).
   * @param aPath
   *        path within the domain for which the cookie is valid
   * @param aName
   *        cookie name
   * @param aValue
   *        cookie data
   * @param aIsSecure
   *        true if the cookie should only be sent over a secure connection.
   * @param aIsHttpOnly
   *        true if the cookie should only be sent to, and can only be
   *        modified by, an http connection.
   * @param aIsSession
   *        true if the cookie should exist for the current session only.
   *        see aExpiry.
   * @param aExpiry
   *        expiration date, in seconds since midnight (00:00:00), January 1,
   *        1970 UTC. note that expiry time will also be honored for session cookies;
   *        in this way, the more restrictive of the two will take effect.
