Abstract: 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.

Abstract: 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.

Abstract: Systems and methods are disclosed for communicating compressed and uncompressed content over a transport layer connection established by an appliance between a client and a server. One method comprises the steps of: establishing, by an appliance, a transport layer connection between a client and a server, and receiving, by the appliance, a first response from the server to a first client request, and a second response from the server to a second client request The first response and the second response has uncompressed data. The method includes transmitting, by the appliance, the first response to the client. The appliance identifies first type of compression from a plurality of compression types for compressing the second response to the client, compresses the second response based on the identified compression type, and transmits the compressed second response to the client.

Abstract: A method for maintaining a cache of dynamically generated objects. The method includes storing in the cache dynamically generated objects previously served from an originating server to a client. A communication between the client and server is intercepted by the cache. The cache parses the communication to identify an object determinant and to determine whether the object determinant indicates whether a change has occurred or will occur in an object at the originating server. The cache marks the object stored in the cache as invalid if the object determinant so indicates. If the object has been marked as invalid, the cache retrieves the object from the originating server.

Abstract: The present invention is directed towards systems and methods for dynamically deploying and executing acceleration functionality on a client to improve the performance and delivery of remotely accessed applications. In one embodiment. The client-side acceleration functionality is provided by an acceleration program that performs a plurality of the following acceleration techniques in an integrated and efficient manner: 1) multi-protocol compression 2) transport control protocol pooling, 3) transport control protocol multiplexing 4) transport control protocol buffering, and 5) caching. The acceleration program establishes a transport layer connection between the client and server, and intercepts network packets at the transport layer.
