Description
A worker process handles all application execution, including authentication and authorization, as well as, ISAPI filter and extension loading. This executable process is called W3WP.exe. When acting as the worker process manager, the www service is responsible for controlling the lifetime of all worker processes that are processing requests. The management console allows it to configure, options such as when to start or recycle a worker process, how many requests to serve before recycling, and what to do if the worker becomes blocked or unable to continue processing requests.
