	// If the username is not found in either place, use a default name.
	if (name == null) name = "World";

	// included from within another servlet or JSP page, this setting
	// will be ignored.
	response.setContentType("text/html");

	// Get a stream that we can write the output to.
	PrintWriter out = response.getWriter();

	// And, finally, do our output.
