Solutions for finding website visitor's geolocation

阅读更多关于 Solutions for finding website visitor's geolocation

I am aware that there are many services which provide geolocation tools for working out where users are visiting from. The website I'm working on is an e-commerce site which runs in multi-territories. When a visitor hits the website it should work out where they are from and show the relevant currency/language for the user. In the past we have used maxmind but I'm wondering if there are better solutions out there. I'm calling out to developers with experience in this area to share their knowledge and expertise on what's available and what the pro's and con's are of various solutions.

问题 How to get the distance of our mobile device from a wifi hotspot kept inside a building? This is basically for navigational purposes inside the building.. Any help would be appreciated. 回答1: If you want to use WiFi for indoor location (step 1 before navigation), then distance to the WiFi Access Points is not the correct approach. Instead use RSSI.

阅读更多关于 Redirect depending on the Country?

We basically have 2 sites ( Java /JSP / Apache Webserver) : something.ca & something.com The .ca is canadian content, and the .com is american content. We need users to be redirected based on the ip addreess. We want US users to get the .com site and Canadian users get the .ca site. What is the best way to do this (at a webserver level or otherwise ) ? Please elaborate. In my web surfing experience, most websites - UPS.com for example - ask the user to select their country site rather than trying to figure it out themselves. They remember the selection in a cookie.
