asp.net WebService如何去掉asmx后缀

现在有一个发布好的WebService，地址是http://hovertree.com:2706/UploadExpenseToConstract.asmx
能不能把最后面的asmx去掉呢？变成
http://hovertree.com:2706/UploadExpenseToConstract
但效果和原来的是一样的？

具体代码:
Global.asax

using System;

namespace ExampleHoverTree
{
    public class Global : System.Web.HttpApplication
    {

        protected void Application_Start(object sender, EventArgs e)
        {

        }

        protected void Session_Start(object sender, EventArgs e)
        {

        }

        protected void Application_BeginRequest(object sender, EventArgs e)
        {
            string hPath= Request.Url.LocalPath.ToString().ToLower();
            if (!hPath.Contains("/hovertreewm.asmx"))
            {
                if (hPath.Contains("/hovertreewm"))
                {
                    Context.RewritePath(hPath.Replace("/hovertreewm", "/hovertreewm.asmx"));
                }
            }
        }

        protected void Application_AuthenticateRequest(object sender, EventArgs e)
        {

        }

        protected void Application_Error(object sender, EventArgs e)
        {

        }

        protected void Session_End(object sender, EventArgs e)
        {

        }

        protected void Application_End(object sender, EventArgs e)
        {

        }
    }
}

HoverTreeWM.asmx

using System.Web.Services;

namespace ExampleHoverTree.HtExample.HWebMethod
{
    /// <summary>
    /// HoverTreeWM 的摘要说明
    /// </summary>
    [WebService(Namespace = "http://hovertree.top/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消注释以下行。 by 何问起
     [System.Web.Script.Services.ScriptService]
    public class HoverTreeWM : System.Web.Services.WebService
    {

        [WebMethod]
        public string HLogin(string hUsername,string hPassword)
        {
           // return hUsername + hPassword;
           return (hUsername.ToLower() == "hewenqi" && hPassword == "HoverTree") ? "登录成功" : "用户名或密码错误";
        }
    }
}
