A method and system for controlling provisioning and access to cache servers with an application programming interface (API). The API includes components for performing various actions including: (i) prepopulating content on at least one cache server from a content server; (ii) expiring content on at least one cache server; (iii) pinning content in a memory of at least one cache server; (iv) assigning resources on at least one cache server in accordance with a quota; (v) retrieving content from at least one cache server; and (vi) flushing deleted content from at least one selected cache. The API may include a security layer. The security layer determines whether a requestor has permission to cause the requested action to be performed.

An inventive apparatus that integrates the operation of a hard disk emulator and a cryptographic accelerator on a single blade server card. An application with cryptographic operations can off load computationally intensive calculations to the cryptographic accelerator so that the speed at which the application performs actions can be increased significantly. Typically, the hard disk emulator is a flash memory component and the accelerator can perform at least modular exponentiation calculations. One bus is employed for communication between the hard disk emulator and the accelerator. Another bus is employed to communicate with other resources off the card. Often, the card is configured to operate as one of a several blade servers in a chassis.

A system and computer implementable method for updating content on servers coupled to a network. The method includes updating an origin server with a version of files used to provide content, retrieving data that indicates an action to be performed on one or more cache servers in conjunction with updating the origin server, and performing the action to update entries in the one or more cache servers. Each entry in each cache server is associated with a subset of the content on the origin server and may include an expiration field and/or a time to live field. An example of a subset of content to which a cache entry may be associated is a Web page. Cache servers are not required to poll origin servers to determine whether new content is available. Cache servers may be pre-populated using push or pull techniques.

Method and system for automatically updating the version of a set of files stored on content servers

A method and system for caching HTTP POST requested content using standard caching rules associated with HTTP GET requests are disclosed. When a POST request is received, it is transformed into a GET request with an identifying tag. The identifying tag includes an index value that is unique to the POST request and is based on the POST request's URL and payload. When the POST request has not been encountered before the POST request's URL and payload is stored in a data store. The client then receives a redirect response including the GET request with the identifying tag that it uses to request the data. When the ensuing GET request with the identifying tag is received it is determined if the requested content has been cached. If so, the cached content is returned to the client. Otherwise, the original POST request is recreated and sent to the origin server to retrieve the content. The returned content is sent to the client and is cached using the GET request with the identifying tag.
