<script language="javascript">
<!--//
document.write('<img src="/tracking/insert.cfm?tagname=#URLEncodedFormat(a
ttributes.tagname)#&pageurl='+escape(document.location)+'&pagere
f='+escape(document.referrer)+'">');
-->
</script>
part of a custom tag that embeds an image in the page dynamically - the source
of the image is a cfm page so i can access the url.pageref variable. Since the
whole block is javascript, people with no js don't get an image, so there's no
call to the cfm page. I use this as part of a hit tracking solution
(coincidentally the subject of another thread right now).

The only problem is that you can't get that value back to the process that
created the "host" page, since we have to assume that it has finished by the
time the call to the image comes in.
