Submit Button. This form control is configured by the <input /> tag and is used to
submit the form. It triggers the action method on the <form> tag and causes the
browser to send the form data (the name and value pairs for each form control) to the
Web server. The Web server will invoke the server-side processing program or script
listed on the form's action property. A sample submit button is shown in Figure 9.12.
