代码：
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Diagnostics; namespace TestMVCRoute { public class myMVCHttpHandler :IHttpModule { public void Dispose() { /* Not needed */ } public void Init(HttpApplication context) { context.BeginRequest += OnBeginRequest; context.EndRequest += OnEndRequest; context.PreSendRequestHeaders += OnHeaderSent; } public void OnHeaderSent(object sender, EventArgs e) { var httpApp = (HttpApplication)sender; httpApp.Context.Items["HeadersSent"] = true; } // Record the time of the begin request event. public void OnBeginRequest(Object sender, EventArgs e) { var httpApp = (HttpApplication)sender; if (httpApp.Request.Path.StartsWith("/media/")) return; var timer = new Stopwatch(); httpApp.Context.Items["Timer"] = timer; httpApp.Context.Items["HeadersSent"] = false; timer.Start(); } public void OnEndRequest(Object sender, EventArgs e) { var httpApp = (HttpApplication)sender; if (httpApp.Request.Path.StartsWith("/media/")) return; var timer = (Stopwatch)httpApp.Context.Items["Timer"]; if (timer != null) { timer.Stop(); if (!(bool)httpApp.Context.Items["HeadersSent"]) { httpApp.Context.Response.AppendHeader("ProcessTime", ((double)timer.ElapsedTicks / Stopwatch.Frequency) * 1000 + " ms."); } } httpApp.Context.Items.Remove("Timer"); httpApp.Context.Items.Remove("HeadersSent"); } } }
webconfig注册：
<httpModules> <add name="myMVCHttpHandler" type="TestMVCRoute.myMVCHttpHandler"/> </httpModules>
</system.web>
或者节点：
<modules runAllManagedModulesForAllRequests="true"> <add name="myMVCHttpHandler" type="TestMVCRoute.myMVCHttpHandler" /> </modules> </system.webServer>
ii6和ii7及以上注册节点结构不同需要注意，所以才贴出了两点。

不过前辈们建议，你最好分清你需要拦截的是什么请求，你的目的是什么，如果是在知情Action控制前拦截，那么你最好使用过滤器，而不是注册一个自定义的IHttpModule。

或者也可以直接在Global.asax.cs文件中使用：
protected void Application_BeginRequest(object sender, EventArgs e) { HttpContext.Current.Request.....; }
默认mvc的Global.asax.cs中没有Application_BeginRequest方法，但是自己复制粘贴过去会起作用，原理是什么还不清楚。
最建议的拦截mvc请求的方式还是用过滤器，
public class DebugActionFilter : System.Web.Mvc.ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext actionContext) { Debug.WriteLine(actionContext.RequestContext.HttpContext.Request); } }
