93 <p>Now go back to the parent directory and do <b>luan luan:http/serve.luan file:site</b>. This will run the Luan web server on port 8080. Try going to <a href="http://localhost:8080/">http://localhost:8080/</a>. You should see the directory. If you click on <b>hi.luan</b> you will see the source.

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.

99 <p>So now you have built your website and you want to publish it to the web. If you have your own domain, create a CNAME record for it pointing to <b>s1.luanhost.com</b>. If you don't have a domain, just use a domain like <b>bob.s1.luanhost.com</b> (anything of the form <b>*.s1.luanhost.com</b>). Assuming your directory is <b>site</b> and you will use the password <b>secret</b>, do the following from the command line: 99 <p>So now you have built your website and you want to publish it to the web.
