Am I using handlers in the wrong way?

Hey, I've never used HTTP Handlers before, and I've got one working, but I'm not sure if I'm actually using it properly. I have generated a string which will be saved as a CSV file. When the user clicks a button, I want the download dialog box to open so that the user can save the file. What I have works, but I keep reading about modifying the web.config file and I haven't had to do that. My Handler:

        private string _data;
        private string _title = "temp";


        public void AddData(string data)
        {
            _data = data;
        }



        public bool IsReusable
        {
            get { return false; }
        }

        public void ProcessRequest(HttpContext context)
        {

            context.Response.ContentType = "text/csv";
        context.Response.AddHeader("content-disposition", "filename=" + _title +         ".csv");
            context.Response.Write(_data);
            context.Response.Flush();
            context.Response.Close();

        }

And this is from the page that allows the user to download: (on button click)

            string dataToConvert = "MYCSVDATA....";

            csvHandler handler = new csvHandler();
            handler.AddData(dataToConvert);

            handler.ProcessRequest(this.Context);

This works fine, but no examples I've seen ever instantiate the handler and always seem to modify the web.config. Am I doing something wrong?

Thanks
