Count the access time of the Asp.net page

During project performance, a simple httpmodule is written to facilitate tracking of the time spent on the PostBack or callback of each page to print the access time.

Compile the following class into a DLL during use, configure it in Web. config, and then open debugview.

Configuration

<Httpmodules>
<Clear/>
<Add name = "tracingmodule" type = "performancetracing. tracingmodule, performancetracing"/>
