title: server side rendering and client side rendering ReactJs
body: <p>I am using react-router to handle both server side rendering and client side rendering in React. But as entry point of my app also has following code :</p>
  
  <pre><code> Router.run(routes, Router.HistoryLocation, function(Handler, state) {
    React.render(&lt;Handler/&gt;, document.body)
     })
  </code></pre>
  
  <p>rendering is getting called twice. How to handle this scenario.</p>
