 ## Remarks  
  An application pool is a group of one or more URLs that are served by a worker process or a set of worker processes. Application pools set boundaries for the applications they contain, which means that any applications that are running outside a specified application pool cannot affect the applications within that application pool.  
 
- If a managed application runs in an application pool with Integrated mode, the server will use the integrated request-processing pipelines of IIS and [!INCLUDE[vstecasp](../wmi-provider/includes/vstecasp-md.md)] to process the request. However, if a managed application runs in an application pool with ISAPI mode, the server will continue to route requests for managed code through Aspnet_isapi.dll and process requests as if they were running in IIS 6.0.
