How to block requests based on country region?

Question

I want to block any request from some country regions.

How to do this in asp.net mvc?

If I were in your place, I'd try to do that in app server settings, not the application itself. — Goran Jovic, Dec 25 '10 at 17:36
I am using shared hosting account so I cannot touch the server. — Second Person Shooter, Dec 25 '10 at 17:37
When implementing any suggested answer, I feel I should point out that a user could potentially get around pretty much any geographical restriction you place upon them with any number of solutions. One of the more popular solutions would be a proxy. — Dan Atkinson, Dec 25 '10 at 23:05
@Dan, can we black-list the proxy addresses? How to know whether or not the incoming request from proxy servers? — Second Person Shooter, Dec 26 '10 at 00:44
@xport. You've got no chance of doing either. There'll be too many proxies to blacklist, and users can simply create their own, and there's no way to distinguish the requests from a normal request. — Dan Atkinson, Dec 26 '10 at 12:59

You can define a HttpModule and then identify the origin of incoming request using one of the methods defined in this SO post to filter the requests

I'd recommend the MaxMind GeoCountry database, which is also the accepted answer for the post @Cybernate recommended. I personally use the paid Region database and am quite satisfied with it.

I'm not sure about going the route of an HttpModule however. I personally feel better with an ActionFilterAttribute which overrides the OnActionExecuting method.
