asp.net中，可通过在<system.web>元素节点下启用<trace>节点元素来激活访问跟踪的。其信息的详细程度，另人吃惊：包括整个请求的过程、请求参数和回传值（viewstate）
system.web.trace <!-- 启用访问跟踪，此信息非常详细，可看到整个访问的全部过程及其中参数的传递。
requestLimit: 跟踪资源限制数
mostRecent: 是否保留最近的跟踪资源，与requestLimit搭配使用。如下，mostRecent为false时，则跟踪资源数为5时，
则不在进行记录跟踪了，反之保持最新的5个
pageOutput: 是否跟踪信息在每个页面上都显示 false则不显示，可通过访问 ${web root path}/trace.axd来查看
-->
<trace enabled="true" requestLimit="5" mostRecent="true" pageOutput="false"/>
启用trace元素后，则可查看访问跟踪的信息
