91 <p>The Luan webserver looks for function named <b>service</b> in the file and calls it to generate the page. Code of the form <b><%=Html.encode[[%>...<%]]%></b> writes its output to <b>Io.stdout</b> which by default is the standard output of the command line. So in <b>service</b> one usually starts by setting <b>Io.stdout</b> to a <tt>text_writer</tt> which writes its output to the HTTP response (to the web browser).</p> 91 <p>The Luan webserver looks for function named <b>respond</b> in the file and calls it to generate the page.
