The present solution is related to a method for distributing flows of network traffic across a plurality of packet processing engines executing on a corresponding core of a multi-core device. The method includes receiving, by a multi-core device intermediary to clients and servers, a packet of a first flow of network traffic between a client and server. The method also includes assigning, by a flow distributor of the multi-core device, the first flow of network traffic to a first core executing a packet processing engine and distributing the packet to this core. The flow distributor may distribute packets of another or second flow of traffic between another client and server to a second core executing a second packet processing engine. When a packet for the flow of traffic assigned to the first core is received, such as a third packet, the flow distributor distributes this packet to the first core.

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.

An apparatus, method and computer program product for guaranteeing network client-server response time while providing a way of putting the client on-hold when the response time temporarily prohibits access to the requested server. The apparatus is implemented within an interface unit connecting a plurality of servers and an on-hold server to the Internet, which is connected to a plurality of clients. According to one aspect of the invention, the method includes the steps of opening a connection between a client and the interface unit; determining which server the client desires a page from; determining the current response time of the requested server; if the response time is acceptable then opening a connection between the interface unit and the requested server if no free connection is open between the interface unit and the requested server; allowing the client to access information on the requested server-via the connections; and closing the connection between the client and the interface unit while keeping open the connection between the interface unit and the requested server. Alternatively, if the response time is not acceptable, then putting the client on-hold by redirecting the client to an on-hold server until the response time of the requested server becomes acceptable. According to a 'on-hold distribution' aspect of the invention, the interface unit determines the on-hold preference of the client and selects the server hosting that on-hold preference. According to another aspect of the invention, instead of utilizing the interface unit, each server has the intelligence to put the client on-hold when applicable.

The present solution is directed towards embodiments of a feature generally referred to as Application Templates or AppTemplates, which allows a administrator of an intermediary, such as an appliance, to configure and manage settings per application on a basis of a subset of application network traffic. Once configured, the application settings can be exported in a file called the Application Template, and imported into other intermediary systems. The Application Template includes the settings for the application as configured via the intermediary.

Systems and methods for application fluency policies

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.

Method and device for performing caching of dynamically generated objects in a data communication network

A device that implements a method for performing integrated caching in a data communication network. The device is configured to receive a packet from a client over the data communication network, wherein the packet includes a request for an object. At the operating system/kernel level of the device, one or more of decryption processing of the packet, authentication and/or authorization of the client, and decompression of the request occurs prior to and integrated with caching operations. The caching operations include determining if the object resides within a cache, serving the request from the cache in response to a determination that the object is stored within the cache, and sending the request to a server in response to a determination that the object is not stored within the cache.
