利用IHttpHandler计算页面的执行时间

来自Cuyahoga 使用自定义的PageHandler处理所有的aspx页面 获取页面的执行时间

 1using System;
 2using System.Web;

 4using System.Web.SessionState;

 6namespace Cuyahoga.Web.HttpHandlers

20        public void ProcessRequest(HttpContext context)
21        {

23            DateTime startTime = DateTime.Now;

25            // Obtain the handler for the current page
26            string aspxPagePath = rawUrl.Substring(0, rawUrl.IndexOf(".aspx") + 5);
27            IHttpHandler handler = PageParser.GetCompiledPageInstance(aspxPagePath, null, context);
28
29            // Process the page just like any other aspx page
30            handler.ProcessRequest(context);

32            TimeSpan duration = DateTime.Now - startTime;
33            context.Response.Write(String.Format("Request finshed. Total duration: {0} ms.", duration.Milliseconds));

webconfig中注册HttpHandler

<httpHandlers>
            <add verb="*" path="*.aspx" type="Cuyahoga.Web.HttpHandlers.PageHandler, Cuyahoga.Web" />
</httpHandlers>
