title: Send simple HTTP request with HTML submit button
body: <p>I have added a submit button to the <code>index.html</code> page that resides on my server side</p>
  
  <pre><code>&lt;form method="get" action="/start"&gt;
      &lt;h5&gt;Start Ad-Placer!&lt;/h5&gt;
      &lt;input type="submit" value="Start"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>I need the button to simply send a <code>http</code> request to <code>http://127.0.0.1:8484/get/start</code> to start some process. Then once the process is done after a few seconds, I need to simply display an alert message with the response message, acknowledging it is done.</p>
  
  <p>How can I do that with minimum efforts (without using JQuery or other libraries).</p>
