The described method and system enables a client at a branch office to retrieve data from a local hosted cache instead of an application server over a WAN to improve latency and reduce overall WAN traffic. A server at the data center may be adapted to provide either a list of hashes or the requested data based on whether a hosted cache system is enabled. A hosted cache at the client side may provide the data to the client based on the hashes. The hashes may be generated to provide a fingerprint of the data which may be used to index the data in an efficient manner.

Method and system of using a local hosted cache and cryptographic hash functions to reduce network traffic

Techniques for synchronization points for state information are described. In at least some embodiments, synchronization points are employed to propagate state information among different processing threads. A synchronization point, for example, can be employed to propagate state information among different independently-executing threads. Accordingly, in at least some embodiments, synchronization points serve as inter-thread communications among different independently-executing threads.

Synchronization points for state information

Content retrieval techniques are described. In an implementation, a determination is made as to whether a client is permitted to receive content requested by the client. When the client is permitted to receive the content, a communication is formed to be communicated via a wide area network that includes a hash list having a hash of each of a plurality of blocks of the content, each hash being configured to enable the client to locate a corresponding one of the blocks of the content via a local area network.

Content retrieval

Described is a technology in which client content requests to a server over a wide area network (WAN) are responded to with hash information by which the client may locate the content among one or more peer sources coupled to the client via a local area network (LAN). The hash information may be in the form of a segment hash that identifies multiple blocks of content, whereby the server can reference multiple content blocks with a single hash value. Segment boundaries may be adaptive by determining them according to criteria, by dividing streamed content into segments, and/or by processing the content based on the content data (e.g., via RDC or content/application type) to determine split points. Also described is content validation using the hash information, including by generating and walking a Merkle tree to determine higher-level segment hashes in order to match a server-provided hash value.

Content identification for peer-to-peer content retrieval

A user-defined rule that specifies a condition and an action to be performed is processed in an electronic messaging system that includes a server and a client by determining at the server whether the condition is satisfied upon an occurrence of an event. Once the condition is satisfied, the action is performed at the server if all resources for performing the action are resident on the server. If one or more of the resources for performing the action are resident on the client, a deferred action message representative of the action is generated. The deferred action message is processed by the client, either immediately if the client is presently logged in to the server, or later when the client next logs in to the server, and the action is performed at the client based on the deferred action message.
