 * usage: Place the following code on the site:

<div id="hpaBanner" style="display:none"><!-- HPA Banner --></div>
<script src="/mstinc/hpa/js/hpa.js" type="text/javascript"><!-- hpa --></script>
<script type="text/javascript">if(typeof hpa!='undefined')hpa.show();</script>

 * You may call hpa.show with an argument which is the domain
 * of the site you wish to use for the config. If you leave it
 * out the script will work out which domain the site is being
 * viewed from.  You may need to specify the domain name in situations
 * where the FI has multiple domain names or a setting for one domain
 * needs to be used for multiple sites.
