title: What's the most efficient / fast way to display website within another website?
body: <p>I am developing my portfolio website and I thought that it would be nice to show websites I've created within my portfolio website.</p>
  
  <p>So say I will have header with navigation of my portfolio website and beneath it a  or  with another website from my portfolio list.</p>
  
  <p>I mentioned  and  as I've heard that they can do such job, but I have no idea of how to use them.</p>
  
  <p>So could anyone please suggest the way that is efficient, browser friendly, wouldn't take a lot of my server resources to display different websites (and will do the job).</p>
  
  <p><strong>Additionally:</strong> the way that I was planning to do this is by having links to different websites like <a href="http://webpage.com/portfolio.php?url=" rel="nofollow">http://webpage.com/portfolio.php?url=</a><strong>http://anotherWebpage.com</strong> so when user clicks it the website shown in the  (or something else) would be <a href="http://anotherWebpage.com" rel="nofollow">http://anotherWebpage.com</a> . Also if possible could someone suggest "AJAX" method that will not require page refresh and will show different webpage in  (or something else ;D ) instantly after user clicks on different links</p>
  
  <p>Thank You )))</p>
