title: Load Javascript Asynchronously
body: <p>I have this java script that I insert into my sidebar. It is for a 350x200 ad banner.</p>
  
  <pre><code>&lt;SCRIPT language="Javascript"&gt;
  var cpmstar_rnd=Math.round(Math.random()*999999);
  var cpmstar_pid=14214;
  document.writeln("&lt;SCR"+"IPT language='Javascript' src='http://server.cpmstar.com/view.aspx?poolid="+cpmstar_pid+"&amp;script=1&amp;rnd="+cpmstar_rnd+"'&gt;&lt;/SCR"+"IPT&gt;");
  &lt;/SCRIPT&gt;
  </code></pre>
  
  <p>^ ^ This is the java script my ad network gave me, I cannot edit it</p>
  
  <p>I want to load this ad banner as fast as possible without hindering the rest of my website. </p>
  
  <p>Currently, what I do is I put this ad tag on a blank html page, then I call that html page using an IFRAME on my sidebar. I heard that IFrames load asynchronously. </p>
  
  <p>Is there any better method that I could use?</p>
