Abstract: The present disclosure is directed towards systems and methods for lightweight identification of flow information by application. A flow monitor executed by a processor of a device may maintain a counter. The flow monitor may associate an application with the value of the counter and transmit, to a data collector executed by a second device, the counter value and a name of the application. The flow monitor may monitor a data flow associated with the application to generate a data record. The flow monitor may transmit the data record to the data collector, the data record including an identification of the application consisting of the counter value and not including the name of the application. The data collector may then re-associate the data record with the application name based on the previously received counter value.

Abstract: Systems and methods of the present disclosure provide for caching, by a device intermediary to a client and a database, a result of a structured query language (SQL) query request. In some embodiments, the device intermediary to a plurality of clients and a database receives a SQL response from the database to a first SQL query request of a client of the plurality of clients. The device may maintain a cache of SQL responses from the database. The device may identify that the first SQL query request matches a rule of a policy for caching SQL responses from the database. The policy may include a cache action to take when the rule is matched. The device may perform, responsive to the policy, on the SQL response the cache action identified by the policy.

Abstract: Improving distribution of traffic from clients to servers is provided. A device intermediary to a plurality of clients and a plurality of servers can receive a request from a client of the plurality of clients to access one of the plurality of servers. The device can determine a hash value based on at least a portion of the request received from the client. The device can identify an index of a plurality of indices listing the plurality of servers repeated a plurality of times in a deterministic shuffled order. The device can apply a cache array routing protocol (CARP) algorithm to a second plurality of servers listed in a subset of the plurality of indices around the index. The device can select a server from the second plurality of servers with a highest hash value based on the application of the CARP algorithm.
