MVC实现二级域名泛解析，并实现了linkExtensions类的Actionlink的不同重载

用Asp.Net MVC实现泛域名解析

实现了如下功能:
www.{language}-{culture}.example.com
www.{controller}.example.com/{action}
www.{clientname}.example.com

using System.Web;
using System.Web.Mvc;
using System.Web.UI;

namespace MvcDomainRouting
{
    public partial class _Default : Page
    {
        public void Page_Load（object sender System.EventArgs e）
        {
            // Change the current path so that the Routing handler can correctly interpret
            // the request then restore the original path so that the OutputCache module
            // can correctly process the response （if caching is enabled）.

            string originalPath = Request.Path;
            HttpContext.Current.RewritePath（Request.ApplicationPath false）;
            IHttpHandler httpHandler = new MvcHttpHandler（）;
            httpHandler.ProcessRequest（HttpContext.Current）;
            HttpContext.Current.RewritePath（originalPath false）;
