You can configure the .NET Agent to monitor ASP.NET applications with multiple Application Domains (AppDomains). This page assumes that you have a working knowledge of AppDomains and are familiar with the AppDomain implementation in your application.

This page does not describe the System Domain, Shared Domain, or DefaultDomain AppDomains that the CLR instantiates before it executes the managed code. If your standalone application runs in the DefaultDomain, see Instrument the DefaultDomain for Standalone Applications.
