| 95 <p>The Luan webserver expects the file to return a function 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 the returned function one usually starts by setting <b>Io.stdout</b> to a <code>text_writer</code> which writes its output to the HTTP response (to the web browser).</p> | 95 <p>The Luan webserver expects the file to return a function and calls it to generate the page.
