C#过滤器HttpModule

C#过滤器HttpModule的使用，如下代码示例：

using System;
using System.Web;

public class HttpModule:IHttpModule
{
public void Dispose()
{
}

public void Init(HttpApplication application)
{
application.BeginRequest+=new EventHandler(Application_BeginRequest);
application.EndRequest+=new EventHandler(Application_EndRequest);
}

void Application_BeginRequest(Object source,EventArgs e)
{
HttpApplication application=(HttpApplication)source;
HttpContext context=application.Context;
context.Response.Write("自定义模块");
}

void Application_EndRequest(Object source,EventArgs e)
{
HttpApplication application=(HttpApplication)source;
HttpContext context=application.Context;
context.Response.Write("自定义模块");
}

}
/*
* 在配置文件中配置
*<system.web>
*<httpModule>
*<add name="HttpModule" type="过滤器类的全名称"/>
*</httpModule>
*</system.web>
