Systems and methods for managing inventory in an online advertising system are described herein. The inventory may comprise advertisement ('ad') impressions. In accordance with certain implementations, the systems and methods enable advertisers to target groups of inventory (e.g., 'run of' inventory groups) made available by publishers and sold at a non-premium rate, while also enabling the publishers to selectively designate certain inventory within a given inventory group as premium. Inventory so designated is automatically excluded from an inventory group to which it would normally belong both during a booking process as well as during an ad serving process.

A web server configured to respond to client requests over a network such as the World Wide Web includes a web listener having a Hypertext Transfer Protocol (HTTP) daemon, a plurality of extension programs configured to perform respective operations, and a web request broker configured to identify one of the programs for responding to a client request, and determine the availability of an instance of the identified program. The web request broker maintains control of multiple instances of each server extension program to provide enhanced server operation without overwhelming server resources. The web request broker maintains a minimum number of instances of the identified program in memory, each executed in its own address space. The web request broker determines whether an available instance of the identified program is available from an existing number of instances, and selectively initiates a new instance of the program if no other instance is available. If no instance is available and the existing number of instances exceeds the maximum prescribed number, then the web request broker returns the reply to the web listener to send a reply over the network that the request was not processed.

A system, method, and computer readable-medium for performing operations associated with browser requests are provided. The system includes a plurality of dispatchers coupled to a plurality of web listeners. Each of the dispatchers receives from a corresponding web listener browser requests received by the corresponding web listener. The system further includes a virtual path manager and a resource manager. The virtual path manager is coupled to the dispatchers through an inter-machine communication mechanism. The virtual path manager indicates to the dispatchers which of a cartridges is associated with the browser requests. The resource manager is coupled to the dispatchers through the inter-machine communication mechanism. The resource manager is configured to assign to each dispatcher of the dispatchers an instance of a cartridge of the cartridges in response to receiving a request for an instance from the dispatcher. The dispatchers are configured to send messages through the inter-machine communication mechanism to the instances that are assigned by the resource manager to the dispatchers. The messages cause the instances to perform the operations associated with the browser requests.
