作为web开发利器，firebug，fillder实乃恩人般的神器。但是它们揭示的是服务器-浏览器之间的巨细事宜，要想了解服务器端的一些细节，还少不了要去F5,F10或者写watch或者各种log。asp.net 其实有自带的trace功能，但是很少有见到一些书籍去介绍或有人去介绍使用经验。话不多说，让我们来启用trace功能以及看它能给出那些关键数据，然后你再考虑下那些场景适合使用此功能。我认为此功能当产品在测试服务器上跑时，特别有用。
一，启用
在<system.web>节点下加如下配置
<trace enabled="true" requestLimit="40" pageOutput="true" localOnly="false" />
二，结果，可以访问url，当前页面在正常页面下端输出trace信息；或者在url后面加?trace.axd,后面一种方式可以在一个窗口查看多个url的trace信息。最终trace保镖如下：
