title: redirect page without changing url
body: <p>I wrote code on my index page</p>
  
  <p><code>window.location.replace(www.mysite.com/index2.html);</code></p>
  
  <p>it redirects, but it also change the url which is obvious.</p>
  
  <p>For e.g. when I run <code>www.mysite.com/index.html</code></p>
  
  <p>It should run <code>www.mysite.com/index2.html</code> page and browser address should display <code>www.mysite.com/index.html</code>.</p>
  
  <p>I want to do this in jquery or javascript.</p>
