I have not come further than to write this javascript function which converts a string to it's hexadecimal value. That will alos obscure it just as fine as the other value. But I have not yet found a way to capture the url from the URL Field, change it and put it back.
<script language="JavaScript">
<!--
var text1 = 'TheURL';
var text2=' ';
for (i=0;i<text1.length;i++){
text2 += '%'
text2 += text1.charCodeAt(i).toString(16);
}
document.write (text2); //Just for testing
//-->
</script>
Best wishes
