摘要： The present application is directed towards systems and methods for providing a cookie by an intermediary device comprising a plurality of packet processing engines executing on a corresponding plurality of cores, the cookie identifying a session of a user that was redirected responsive to a service exceeding a response time limit. The cookie may be generated with identifiers based off a name of a virtual server managing a service of a server, and a name of a policy associated with the virtual server. Each packet processing engine of the plurality of packet processing engines may interpret cookies generated by other packet processing engines due to the name of the virtual server and name of the policy, and may provide preferred client connectivity based on cookies included in requests for access to a service.

摘要： A method and system for generating a web log that includes transaction entries from transaction queues of one or more cores of a multi-core system. A transaction queue is maintained for each core so that either a packet engine or web logging client executing on the core can write transaction entries to the transaction queue. In some embodiments, a timestamp value obtained from a synchronized timestamp variable can be assigned to the transaction entries. When a new transaction entry is added to the transaction queue, the earliest transaction entry is removed from the transaction queue and added to a heap. Periodically the earliest entry in the heap is removed from the heap and written to a web log. When an entry is removed from the heap, the earliest entry in a transaction queue corresponding to the removed entry is removed from the transaction queue and added to the heap.

摘要： The present application is directed towards systems and methods of state migration in a multi-core system. An external process on a client or server may initiate a plurality of connections with the multi-core system, such that some cores have a plurality of connections and others have none. The present invention provides systems and methods for redirecting a connection or migrating the state of a connection from being associated with a first core with a plurality of connections to a second core with no connections.

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.
