title: How to POST request while exposing localhost using localtunnel
body: <p>I'm using node js as server. Do i have to configure index.js file while using localtunnel?
  While submitting form, which URL do I have to specify? should i use URL provided by localtunnel.   </p>
  
  <pre><code>&lt;form name="formname" action="http://localhost:3000/register" method="post"&gt;
  </code></pre>
  
  <p>I know its a silly question. Can somebody provide a small guidance?</p>
