Defines an identifier for application domains that a cache implementation can use to interact with a host environment.
Assembly: System.Runtime.Caching (in System.Runtime.Caching.dll)
Thetype exposes the following members.
A .NET Framework host environment such as ASP.NET can use the interface to define strings that identify individual application domains. The host environment implements the interface. This interface is then available to ObjectCache implementations through the Host property.
A cache implementation uses this reference to obtain an identifier for the application domain. In ASP.NET, cache implementations use the application identifier to construct identifiers for cache performance counters. This provides names for performance counter instances that can be distinguished between application domains when multiple application domains are running.
