Trace Visitor GeoLocation in Asp.Net C#



In this post Trace Visitor GeoLocation in Asp.Net C#

Geolocation means recognizing or identifying the user’s location or any device’s location by the use of various data collection mechanisms. Most of the time these types of services use GPS devices or network routing addresses. Geolocation varies in support of various devices. Some browsers support geolocation while some don’t. So it can’t be said confidently that geolocation is always possible for a web application.
