How to get user location data without using HTML5 or Google maps

First of all, this might not be accurate location and this is more like a JS IP2Location concept.

I recently worked on a project that required to detect the user country and redirect to the proper website based on that, I'm on Drupal and I know there are contrib modules out there to do that. but we have Varnish enabled on our server so PHP won't execute at all. So I had to think about a better and easy solution for that.

I couldn't use HTML Geocoder because it requires user permission to get the current location. I couldn't use Google geolocater (I cannot rem why, I think they have deprecated their API).

So only solution I had was this, this is a tiny little hack to get the user location and couple of other information from appspot.com :).

    $.ajax({
        url: "http://ajaxhttpheaders.appspot.com",
        dataType: 'jsonp',
        success: function (headers) {
            country = headers\['X-Appengine-Country'\];
            if (country == 'US') {
                return;
            } else {
                // your code here
            }
        }
    });
