How to best accomplish this

[PDSBILL]

I believe the problem is that I am using an older version (15.2.50) of Intraweb 
I am going to update but have a number of TMS IWcomponents that are a bitch to install.
Is there another work around for my Version?

Code:

//This access Violates on the  webapplication.Terminate('hello');
procedure TIWServerController.IWServerControllerBaseBeforeNewSession(
  const aUrlPath: string; aRequest: THttpRequest; out vCanCreate: Boolean);
begin
    webapplication.Terminate('hello');
    VCanCreate:=False;
end;

// this works
procedure TIWForm14.IWButton1Click(Sender: TObject);
begin
  webapplication.terminate('test 123');
end;
