  try

    // Set the name of the CGI module which runs our report

    CGIRunner.CGIModule := CGIModuleName;

    CGIRunner.Execute(WebApplication, WebApplication.Request);

    // Check status result. Zero indicates success. Anything else is an error

    if CGIRunner.StatusResult = 0 then

    begin

      s:=CGIRunner.ResponseContent.Text;

      //Problem here: CGIRunner.ResponseContent.Text is empty

      with WebApplication.Response do

        begin
