How can you tell the difference between a request going to 127.0.0.1 and localhost.

This line of code on Windows 7 and VS2010 built-in web server can not tell the difference.

if (Request.ServerVariables["SERVER_NAME"].ToLower() == "localhost")
{

}

try hitting your own built-in web server with: http://127.0.0.1/ and then http://localhost/
