Re: How do web beacons work?

I hadn't come across Yahoo's terminology before but I highly doubt it is 
anything more advanced than an image HREF to a unique logging host.  
Referrer and cookie information will come along, voila!  A Web Beacon.  
This of course is just my wag at what they are doing, and maybe I'm 
wrong.  Though I wouldn't consider this to be a Honeytoken either, since 
it isn't deployed to identify unwanted,unexpected or known-bad activity.
