Web.Config System.web

Question

Hi

 

What does the below code does

 

<system.web>

<customErrors mode="Off"/>

<compilation debug="true" targetFramework="4.5"/>

<httpRuntime targetFramework="4.5"/>

<httpRuntime targetFramework="4.5" maxRequestLength="20480" executionTimeout="1600" />

</system.web>

 

Thanks
