Title: How to Change an Application Pool Queue Length Limit in IIS in Windows Server 2003
Objective: The objective of this demo is to teach you how to change an application pool queue length limit in IIS in Windows Server 2003. Application pool queue length limits prevent large numbers of requests from queuing up and overloading your server. When application pool queue length limits are enabled, IIS monitors the number of requests for a designated application pool queue before queuing a new request. If adding the new request to the queue exceeds the queue size, the server rejects the request and sends a 503-error response (that can't be customized) to the client. However, requests that are already queued remain queued even if the limit is changed to a value that is less than the current queue length.
