An improved web server design includes a kernel-based listener service that is configured by a user-mode based administrative process. When a web request is received by the listener service it is placed in a queue associated with an application pool having one or more user-mode web applications configured to process received web requests. The web applications are selectively started and stopped by the administrative process.

Web server architecture

Improved methods and arrangements are provided in which a web server or like process includes a kernel-mode universal listener (UL) capability that utilizes the URL associated with an HTTP request to determine which user-mode worker process/application is to handle the request and route the request to the targeted worker process/application. Thus, for example, one implementation includes a kernel-mode HTTP listener that is selectively configured via a Web admin service (WAS) based a configuration store. The resulting configuration file in the kernel-mode UL process defines a plurality of configuration groups and application pools, etc. The Configuration groups include certain URL's, which have configurable properties applied to them. The configurable properties define which user-mode worker process is to handle HTTP requests. Fore example, application pools can be provided, which identify a worker process or processes that the HTTP requests are routed to. In certain implementations, an HTTP request queuing capability is also provided. The request queue provides time for worker processes/applications to start or get ready.

Methods and arrangements for routing server requests to worker processes based on URL

A web server arrangement is provided having a kernel-mode listener service capable of receiving web requests and providing the web requests to at least one user mode web application. The listener service and the web application are operatively configured by a user-mode administrative process. The administrative process is configured to determine when a web application needs to be recycled and to selectively recycle web applications.
