<h3>Caching problem?</h3>
<p>Dynamic created SCRIPT elements will not fire the onload event on refresh on secure connection if the script is empty (no content whatsoever).</p>
<p>The code to reproduce the problem:</p>
<xmp>
function init() {
alert("onload fired on body!");
var scriptElement = document.createElement('script');
scriptElement.readyState = 'loaded';
scriptElement.onload = function() {
alert("onload fired on script!");
}
scriptElement.type = 'text/javascript';
scriptElement.src = 'empty.js';
var headElement = document.getElementsByTagName('head')[0];
headElement.appendChild(scriptElement);
}
</xmp>
