Sending Country Code of Visitor from one web Application to another Using .NET (ASP/ MVC )

Question

I am creating an application which tracks user information such as country, city IP of the web site. I send the information about visitors to my second web application which will be updated automatically when a visitor visits my 1st web application which has JavaScripts to track all the information.

Example (Application in which Visitor Landed) . WebPage

<script language="JavaScript" src="http://j.maxmind.com/app/geoip.js"></script>
<script language="JavaScript">
    geoip_country_code() //CountryCode
    geoip_country_name() //CountryName
    geoip_city() //City
</script>  

(Application in which I will track information about the Visitor) .WebPage ?

Please help me through this :S. Will I be using Ajax or something like this which will be giving updates automatically on my second application?

(Programming Language C# is prefered)

Answer 1

Here is an approach

Instead of making cross domain calls between two applications via Ajax,

• you can write a simple web service on your web application 2,
• make an ajax call to your webapplication 1
• web application 1 calls the service on webapplication 2 to update the data from server side
