ASP.NET 2.0 is part of a new process and AppDomain management system whose code name is WebHost. In brief, WebHost is an extensible model for application activation and hosting. It s a common layer of code that hosts and manages applications that can be activated and controlled through messages. Examples of such message-based managed applications are currently limited to ASP.NET 2.0 and Indigo applications. Bits and pieces of WebHost appear in the IIS 6.0 architecture and made their debut in the aspnet_isapi module on IIS 5.0 and Windows 2000. Starting with the .NET Framework 2.0, the WebHost platform has been finalized as managed components supplied by various providers, including ASP.NET, Indigo, and IIS itself. WebHost manages the lifetime of worker processes, AppDomains, and application components. In doing so, it also provides services such as configuration management, dynamic compilation, and output caching. Applications managed by WebHost must define the high-level components listed in Table 11-1.

Description Manages the lifetime of AppDomains and application components within the worker process. Already implemented as an internal component of aspnet_isapi 1.x, it is now generalized to handle messages arriving on all protocols (including HTTP) and route them to AppDomains. A library loaded inside the worker process that handles communication with the WebHost host platform (IIS). For example, it answers ping requests. The component also interfaces with the Process Host, a managed object that controls the execution of .NET applications. Provides the ability to host the CLR within the worker process and hosts the application manager and the protocol handlers. Components that retrieve protocol-specific requests from a queue and service them.

The ASP.NET Runtime Environment
WebHost is expected to provide a number of benefits, such as a single activation and hosting model for all message-activated applications and support for activation over multiple protocols (not just HTTP). WebHost provides a common set of services for all message-activated applications, regardless of the protocol recognized by the particular application. Services include process and AppDomain recycling, health monitoring, and deadlock detection. If you re a former ASP.NET 1.x programmer and know the basics of IIS 6.0, you think of the WebHost environment as a common layer of code that exposes and personalizes some Web server services to message-activated managed applications. To support these goals, in fact, WebHost clients must implement the process host and application manager components.
Important The WebHost environment is involved with request processing only if the IIS 6.0 process model is used. If ASP.NET 2.0 is hosted on IIS 5.0 or if the IIS 5.0 process model is used, ASP.NET uses its own worker process aspnet_wp.exe. In this case, the ASP.NET ISAPI extension receives the request and creates the application manager, which in turn creates an instance of the AppDomain s protocol handler to service the request.
The WebHost Process Manager
The WebHost process manager is a Windows service provided by IIS. It starts up and shuts down worker processes and initiates all process management actions, such as recycling and idle detection. The WebHost process manager receives messages from message receivers, which are components that listen to special incoming packets. Message receivers include a component for HTTP messages based on the IIS 6.0 http.sys kernel-mode driver and the SOAP-TCP listener adapter provided with Indigo. The WebHost process manager passes control to the IIS 6.0 worker process together with information about the WebHost application to start (such as an ASP.NET 2.0 application). The information includes a unique application ID, the root URL and the physical location of the application, the ID of the corresponding IIS 6.0 application pool, the logon account, and a set of protocols that can be used to activate the application. Figure 11-1 shows the overall WebHost architecture.
