ASP.NET Global 全局事件处理

添加Global文件，名字不要改

Global类说明：

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.SessionState;

namespace WebApplication1
{
    public class Global : System.Web.HttpApplication
    {
        /// <summary>
        /// 网站启动的时候会被调用
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void Application_Start(object sender, EventArgs e)
        {
            File.AppendAllText(@"c:1.txt", DateTime.Now + "Application_Start
");
        }

        /// <summary>
        /// 某一个session启动的时候会被调用
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void Session_Start(object sender, EventArgs e)
        {
            File.AppendAllText(@"c:1.txt", DateTime.Now + "Session_Start
");
        }
        /// <summary>
        /// 当一个请求过来的时候会被调用,html静态文件是iis直接把文件给到浏览器,不经过asp.net引擎处理
        /// 所以不会调用Application_BeginRequest方法
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void Application_BeginRequest(object sender, EventArgs e)
        {
            File.AppendAllText(@"c:1.txt", DateTime.Now + "Application_BeginRequest" + Context.Request.RawUrl + "
");
        }

        protected void Application_AuthenticateRequest(object sender, EventArgs e)
        {

        }

        /// <summary>
        /// 当web应用程序发生错误的时候会被调用
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void Application_Error(object sender, EventArgs e)
        {
            File.AppendAllText(@"c:1.txt", DateTime.Now + "Application_Error" + Context.Error + "
");
        }
        /// <summary>
        /// 当session结束的时候会被调用,如session超时,设置session 20分钟过期,到了这时间就被调用
        /// 只有进程内session,也就是InProc过期的时候才会调用Session_End,进程外session不会调用此方法
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void Session_End(object sender, EventArgs e)
        {
            File.AppendAllText(@"c:1.txt", DateTime.Now + "Session_End
");
        }
        /// <summary>
        /// 当web应用程序退出的时候会被调用
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void Application_End(object sender, EventArgs e)
        {
            File.AppendAllText(@"c:1.txt", DateTime.Now + "Application_End
");
        }
    }
}

 设置session过期时间：

<configuration>
    <system.web>
      <sessionState timeout="1"></sessionState>
      <compilation debug="true" targetFramework="4.5" />
      <httpRuntime targetFramework="4.5" />
    </system.web>
</configuration>
