i think maybe nathan was referring to our geoLocator project. the db is out-of-date by now (the guy who does the updates is splitting his time between remodeling his home in the UK & the middle east). the project was mainly designed to pick up users' locale for i18n apps. in any case, we've found the ip-to-country/locale to be >90% accurate, even w/that dinosaur of a db. accuracy drops off the more detailed the location, in some parts of the world <50% for city-level. if you use one of the ip databases, i strongly urge you to use a binary version of the db if it exists. http calls & sql queries suck wind in comparison especially if you're aiming for anything like real time. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:349497 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
