How to restrict google from redirecting

I believe you may experience that when you open a browser and type www.google.com, you will be redirected to the country you connected.

If I don't want to redirect, what should I do to restrict it. To restrict it you need to append "ncr" like "www.google.com/ncr". The "ncr" means Non-Country-Redirect, therefore you will not be redirected to your country. Sometime we have to do that because we may get different result from regional server.
