A system for and method of allocating a resource to a service request based on application of a persistence policy is described. In one embodiment, upon or after allocation of a resource to a resource request, an entry representing the allocation is made in a data structure using a first index derived from information relating to the resource request if such is available. An entry representing the allocation is also made in the data structure using a second index derived from information relating to the resource request. When a resource request is received, the data structure is accessed using the first index if such is available. If an entry corresponding to the first index is available, the resource corresponding to the entry is allocated to the request. If the first index or an entry corresponding to the first index is unavailable, the data structure is accessed using the second index. If an entry corresponding to the second index is available, the resource corresponding to the entry is allocated to the request. If an entry corresponding to the second index is unavailable, a resource is allocated to the request based on application of a load balancing policy or other persistence policy. One or more entries are then made in the table corresponding to the new allocation.

Method of and system for allocating resources to resource requests based on application of persistence policies

Systems and methods are described for analyzing the content of resource requests. A tokenizer parses the resource request and derives a key therefrom. A database associates values of the key with categories of service. An association engine uses the key to obtain one or more matching entries from the database, and derive therefrom the desired category of service for the resource request. A cookie engine derives cookie information from a cookie located in the resource request. A session engine derives session information from a session identifier located in a handshake message associated with the resource request. The desired category of service, the cookie information, and the session information are each useful for allocating a resource to the resource request.

Method of and system for analyzing the content of resource requests

Systems and related methods are described for handling one or more resource requests. A protocol engine receives a resource request in accordance with a prescribed protocol, and a classification engine determines a desired class of service for the request. An analysis engine optionally analyzes the request, and, responsive thereto, determines a desired sub-class of service for the request. A policy engine then allocates a resource to the request responsive to one or both of the desired class of service, and the desired sub-class of service.
