Well there is some other stuff you can take into account. for example lets say I have 3 subscribers behind the same IP address ... user A requests feed with ip addess 10.10.10.10 with agent=iTunes for windows -- > subscribers=1 user a requests the feed again one hour later with itunes for windows -- > counted as the same user. subscribers=1 User B then 1 hour later requests feed with ip address 10.10.10.10 with agent = fireant for windows -- > Here we have to make a choice. Do I count this as a new subscriber assuming there are more than one people behind this address, or do I count this as the same user assuming he has two aggrigators installed. Up to you, but in my system I count it as the same user (I try to fall to the side of too strict). So in my system ... counted as the same user subscribers=1 (I've just lumped two people together perhaps) User C then requests the feed from ip 10.10.10.10 with agent=fireant for Mac --> this time we see that it's a macintosh OS where as the last from this IP was a windows install. --> Here I go ahead and make the assumption that this is in fact a different user, as it is very cleraly a different machine (even though its from the same IP) subscribers=2 So as above, you'd have 3 users with the same IP address. In my system it would count them as 2 ... I could have counted them as 3, but I made the rule that lumps some together because I'd rather lose one here and there than gain 3 because of people like me who have Fireant, iTunes, and thunderbird all pinging away. IP address is important HTTP user agent can also give you great information such as: * client application * client OS (sometimes) * number of users that this requests services (sometimes) - Dave -- http://www.DavidMeade.com ------------------------ Yahoo!
