摘要： Systems and methods for reducing file sizes for files delivered over a network are disclosed. A method comprises receiving a first file comprising sequences of data; creating a hash table having entries corresponding to overlapping sequences of data; receiving a second file comprising sequences of data; comparing each of the sequences of data in the second file to the sequences of data in the hash table to determine sequences of data present in both the first and second files; and creating a third file comprising sequences of data from the second file and representations of locations and lengths of said sequences of data present in both the first and second files.

摘要： This disclosure is directed to dictionary-based compression, which may be employed to achieve stateful header compression without maintaining a complete deflate state. The compressor may maintain a history of data streams compressed by the compressor, compressed according to a compression dictionary. Responsive to the compression of the one or more data streams, the compressor may delete the first compression dictionary from the memory. Subsequent to the deletion, the compressor may compress an additional data stream using the maintained history. The compressor may generate a second compression dictionary from at least one of: the maintained history and a portion of the additional data stream. The compressor may allocate memory for a compression state of the additional data stream and may load the maintained history into the compression state.

摘要： A method for compressing a stream of application layer network traffic communicated over a transport layer connection of a virtual private network connection between a client and a server using an appliance. The appliance intercepts one or more transport layer packets of a stream of application network traffic communicated via a transport layer connection of a virtual private network connection between a client and a server. The appliance accumulates data from a payload of the intercepted transport layer packets, determines data accumulated for transmission should be compressed based on one or more compression trigger, and compresses the accumulated data into a self-contained compression block for transmission.

摘要： The present invention is directed towards a method and system for providing granular timed invalidation of dynamically generated objects stored in a cache. The techniques of the present invention incorporates the ability to configure the expiration time of objects stored by the cache to fine granular time intervals, such as the granularity of time intervals provided by a packet processing timer of a packet processing engine. As such, the present invention can cache objects with expiry times down to very small intervals of time. This characteristic is referred to as “invalidation granularity.” By providing this fine granularity in expiry time, the cache of the present invention can cache and serve objects that frequently change, sometimes even many times within a second. One technique is to leverage the packet processing timers used by the device of the present invention that are able operate at time increments on the order of milliseconds to permit invalidation or expiry granularity down to 10 ms or less.

摘要： The present invention is directed towards a method and system for providing a technique referred to as flash caching to respond to requests for an object, such as a dynamically generated object, from multiple clients. This technique of the present invention uses a dynamically generated object stored in a buffer for transmission to a client, for example in response to a request from the client, to also respond to additional requests for the dynamically generated object from other clients while the object is stored in the buffer. Using this technique, the present invention is able to increase cache hit rates for extremely fast changing dynamically generated objects that may not otherwise be cacheable.

摘要： The present invention is directed towards a “flash crowd” technique for handling situations where the cache receives additional requests, e.g., nearly simultaneous requests, for the same object during the time the server is processing and returning the response object for a first requestor. Once all such nearly simultaneous requests are responded to by the cache, the object is flushed from the cache, with no additional expiry time or invalidation action needed. This technique of the present invention enables data to be cached and served for very small amounts of time for objects that would otherwise be considered non-cacheable. As such, this technique yields a significant improvement in applications that serve fast changing data to a large volume of concurrent users, such, for example, as real time stock quotes, or a fast evolving news story.

摘要： The present invention is directed towards a method and system for modifying by a cache responses from a server that do not identify a dynamically generated object as cacheable to identify the dynamically generated object to a client as cacheable in the response. In some embodiments, such as an embodiment handling HTTP requests and responses for objects, the techniques of the present invention insert an entity tag, or “etag” into the response to provide cache control for objects provided without entity tags and/or cache control information from an originating server. This technique of the present invention provides an increase in cache hit rates by inserting information, such as entity tag and cache control information for an object, in a response to a client to enable the cache to check for a hit in a subsequent request.

摘要： The present solution is directed towards a policy-based intermediary that dynamically and flexibly injects content in responses between a client and a server based on one or more policies. The present solution addresses the challenges of injecting content in a client-server transaction. The intermediary determines when and what content to inject into a response of a client-server transaction based on a request and/or response policy. The injected content may include timestamp and/or variable tracking of different events in a client-server transaction. For example, when an intermediary appliance is deployed in a system to accelerate system performance and improve user experience, the appliance may inject content based on policy to monitor the acceleration performance of the deployed appliance.
