I found this stub of code on a website:<p><script type="text/javascript">
var _kmq = _kmq || [];
var _kmk = _kmk || '<something here>';
function _kms(u){
setTimeout(function(){
var d = document, f = d.getElementsByTagName('script')[0],
s = d.createElement('script');
s.type = 'text/javascript'; s.async = true; s.src = u;
f.parentNode.insertBefore(s, f);
}, 1);
}
_kms('//i.kissmetrics.com/i.js');
_kms('//doug1izaerwt3.cloudfront.net/' + _kmk + '.1.js');
</script><p>I understand most of it, but not the "doug1izaerwt3" part.<p>Can someone throw some light on this? TiA.
It's just a hostname. Hostnames can be any arbitrary sequence of letters, numbers, and hyphens up to 63 characters long. It may or may not have semantic meaning to whoever wrote the code; it looks pretty random to me.
