Detect your location by IP address using Salesforce and external geolocation provider REST API

Usually I feel curious about who visits my blog, from which country and from which city.

I found some interesting post about showing location of customer on google map using Salesforce and as external geolocation detection provider.

However, this provider doesn’t allow you to use it without registration and revealing your actual location. So I felt engaged in building my own custom similar solution and finally I have built it.

I use in my solution three different geolocation detector providers, since looks like all of them give wrong information at least about my own IP address.
Anyway they have different accuracy, and I believe their accuracy may vary upon IP address, so each user can select different providers and find which one shows more exact information in his or her particular case.

There is my version of code

<apex:page controller="GL" cache="false" sidebar="false" showHeader="false" title="Geolocation Detection">
<apex:includeScript value=""/>
<script type="text/javascript">
window.onload = function(){

//Javascript function that loads the map. Notice I can simply use the normal Visualforce merge fields for lat and long.
function loadMap() {
var latlng = new google.maps.LatLng({!latitude}, {!longitude});
var myOptions = {
zoom: 11,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

var marker = new google.maps.Marker({
position: latlng,
title:"IP Location"

// To add the marker to the map, call setMap();
