Technology is described for actively responding to data storage traffic. The technology can provide an application program interface; receive, via the application program interface, from an application, a command to query a data storage attribute associated with a virtual data storage component; query the associated virtual data storage component; and return to the application a value for the data storage attribute.

Actively responding to data storage traffic

A method of and system for presenting enriched video viewing analytics is presented. A method of presenting enriched statistical and analytical information includes receiving a catalog of a plurality of content items. Each content item has associated metacontent characterizing the content item. The method also includes receiving and storing operations of a user for interacting with one or more of the content items. The method further includes determining use and/or viewing statistics for, for example, the content items, metacontent associated with the content items, the numbers and types of devices viewing the content items, subscriber information, household information, and/or viewer demographic information for past and present time periods. The method also, optionally, includes estimating the likelihood of future user interaction operations.

A system uses a proxy server to authenticate a client with an authentication protocol that does not support caching. Rather than cache the client's authentication credentials, or access a client account manager for each network request generated by the client, the proxy server issues a cookie to an authenticated client and authenticate the client for subsequent request on the basis of the cookie.

Cookie-based acceleration of an authentication protocol

A software framework configured to execute in a computer system and adapted to monitor statistics associated with one or more servers coupled to the computer system is disclosed. A data structure is configured to store statistics associated with the one or more servers coupled to the computer system. A server-monitoring thread is configured to update at least some of the statistics stored in the data structure, the server-monitoring thread to execute on a processor of the computer system. An application programming interface (API) responsive to a plurality of software modules executes in the computer system, the API is configured to process requests from the plurality of software modules for (i) adding or removing servers in the data structure or (ii) accessing statistics from the data structure. The computer system may be a network cache.

Server monitoring framework

Web server and Web cache operations to permit efficient user authorization and cross-domain authentication without repeated login requirements are described. Techniques to prevent unauthorized use of protected resources are also discussed.

Method and apparatus for providing efficient authorization services in a web cache

A novel software framework monitors server statistics for a plurality of software modules and makes its collected statistics available to those modules. Unlike prior implementations, the framework provides shared server-monitoring code through which the plurality of software modules can monitor various types of servers, such as authentication servers, ICAP servers, origin servers, hierarchical proxy servers and so forth. Because the same server-monitoring code is accessed by each of the software modules, the overall amount of code that is written, compiled and executed may be reduced. Moreover, the shared server-monitoring code is not protocol-dependant and therefore may be coded outside of the kernel-level protocol engines. Preferably, the shared server-monitoring code is implemented as a user-level thread or process.
