ASP.NET MVC3关于生成纯静态后如何不再走路由直接访问静态页面

public class MyHandler:IHttpModule
{
public void Init(HttpApplication application)
{
application.BeginRequest +=
(new EventHandler(this.Application_BeginRequest));
application.EndRequest +=
(new EventHandler(this.Application_EndRequest));
}
private void Application_BeginRequest(Object source,
EventArgs e)
{
// Create HttpApplication and HttpContext objects to access
// request and response properties.
HttpApplication application = (HttpApplication)source;
HttpContext context = application.Context;
string filePath = context.Request.FilePath;
string fileExtension =
VirtualPathUtility.GetExtension(filePath);
if (fileExtension.Equals(".html"))
{
context.Response.WriteFile(context.Server.MapPath(filePath));//直接走静态页面
//此处可以加入缓存，条件也可以根据需要来自己定义
context.Response.End();
}
}
private void Application_EndRequest(Object source, EventArgs e)
{
HttpApplication application = (HttpApplication)source;
HttpContext context = application.Context;
string filePath = context.Request.FilePath;
string fileExtension =
VirtualPathUtility.GetExtension(filePath);
if (fileExtension.Equals(".html"))
{
context.Response.Write("<hr><h1><font color=red>" +
"HelloWorldModule: End of Request</font></h1>");
}
}
public void Dispose() { }
}

<httpModules>
<add name="MvcTest.MyHandler" type="MvcTest.MyHandler"/>
</httpModules>

private void Application_BeginRequest(Object source,
EventArgs e)
{
// Create HttpApplication and HttpContext objects to access
// request and response properties.
HttpApplication application = (HttpApplication)source;
HttpContext context = application.Context;
string filePath = context.Request.FilePath;
string fileExtension =
VirtualPathUtility.GetExtension(filePath);
if (fileExtension.Equals(".html"))
{
//判断缓存是否存在，不存在加入缓存，调用生成静态的类和方法
//产品过期，移除静态文件，302重定向
if (System.IO.File.Exists(context.Server.MapPath(filePath)))
{
context.Response.WriteFile(context.Server.MapPath(filePath));
context.Response.End();
}
}
