An access system provides identity management and/or access management services for a network. An application program interface for the access system enables an application without a web agent front end to read and use contents of an existing encrypted cookie to bypass authentication and proceed to authorization. A web agent is a component (usually software, but can be hardware or a combination of hardware and software) that plugs into (or otherwise integrates with) a web server (or equivalent) in order to participate in providing access services.

Systems and methods for providing fast and efficient data compression using a combination of content independent data compression and content dependent data compression. In one aspect, a method for compressing data comprises the steps of: analyzing a data block of an input data stream to identify a data type of the data block, the input data stream comprising a plurality of disparate data types; performing content dependent data compression on the data block, if the data type of the data block is identified; performing content independent data compression on the data block, if the data type of the data block is not identified.

Content independent data compression method and system

In an Item-based system, Images (e.g., JPEG, TIFF, bitmap, and so on) are treated as core platform objects (“Image Items” or, more simply, “Images”) and exist in an “Image Schema” that provides an extensible representation of an Image in the system—that is, the characteristics of an Image and how that Image relates to other Items (including but not limited to other Images) in the system. To this end, the Image Schema defines the properties, behaviors, and relationships for Images in the system, and the Schema also enforces rules about Images, for example, what data specific Images must contain, what data specific Images may optionally contain, how specific Images can be extended, and so on and so forth.

Systems and methods for providing accelerated loading of operating system and application programs upon system boot or application launch are disclosed. In one aspect, a method for providing accelerated loading of an operating system comprises the steps of: maintaining a list of boot data used for booting a computer system; preloading the boot data upon initialization of the computer system; and servicing requests for boot data from the computer system using the preloaded boot data. In another aspect, a method for providing accelerated launching of an application program comprises the steps of: maintaining a list of application data associated with an application program; preloading the application data upon launching the application program; and servicing requests for application data from a computer system using the preloaded application data.

Systems and Methods for Accelerated Loading of Operating Systems and Application Programs

Data storage controllers and data storage devices employing lossless or lossy data compression and decompression to provide accelerated data storage and retrieval bandwidth. In one embodiment of the invention, a composite disk controller provides data storage and retrieval acceleration using multiple caches for data pipelining and increased throughput. In another embodiment of the invention, the disk controller with acceleration is embedded in the storage device and utilized for data storage and retrieval acceleration.

Data Storewidth Accelerator

An apparatus and method for caching data in a storage device (26) of a computer system (10). A relatively high-speed, intermediate-volume storage device (25) is operated as a user-configurable cache. Requests to access a mass storage device (46) such as a disk or tape (26, 28) are intercepted by a device driver (32) that compares the access request against a directory (51) of the contents of the user-configurable cache (25). If the user-configurable cache contains the data sought to be accessed, the access request is carried out in the user-configurable cache instead of being forwarded to the device driver for the target mass storage device (46). Because the user-cache is implemented using memory having a dramatically shorter access time than most mechanical mass storage devices, the access request is fulfilled much more quickly than if the originally intended mass storage device was accessed. Data is preloaded and responsively cached in the user-configurable cache memory based on user preferences.
