Abstract: The present invention is related to a method for routing requests among a plurality of database servers. A device intermediary to a client and a plurality of database servers receives a request to access a database provided by the plurality of database servers. The plurality of database servers can include a first database server configured to process write requests and one or more second database servers configured to process read requests. The device determines that the request to access the database is a read request. The device identifies, responsive to determining that the request is a read request, one of the one or more second database servers to send the request instead of the first database server. The device then transmits the request to the identified second database server.

Abstract: The present disclosure is directed to systems and methods for performing load balancing and message routing by a device intermediary to a plurality of short message peer to peer (SMPP) clients and a plurality of SMPP servers. The device can receive a request from an SMPP client to establish an SMPP session, replace a first sequence identifier in the request with a second sequence identifier generated by the device, and store a mapping of the second sequence identifier to the first sequence identifier. The device can select an SMPP server to forward the request with the second sequence identifier and receive a response from the SMPP server with the second sequence identifier. The device can identify, from the mapping, the first sequence identifier and the connection to the SMPP client using the second sequence identifier to forward the SMPP response with the first sequence identifier.

Abstract: The present application is directed towards systems and methods for application specific load-balancing for web servers. A device intermediary to a plurality of clients and a plurality of services executing on a plurality of servers, may receive a request from a client for an application. The device may identify an identifier for the application from a table comprising a list of applications and a corresponding identifier assigned to each application. In an embodiment, the device may establish one or more monitors to monitor each service to determine applications available on each service. In an embodiment, the device may determine that one or more services of the plurality of services provides the application and select a service from the one or more services to forward the request. The device may forward the request to the selected service.

Abstract: The present invention is related to a method for load balancing and connection multiplexing structured query language (SQL) queries among a plurality of database servers. A device intermediary to a plurality of clients and a plurality of database servers receives an SQL query to access a database provided by the plurality of database servers from a client via a first connection established between the device and the client. The device identifies for the SQL query a policy for selecting among the plurality of servers. The policy includes an expression to identify predetermined data from content of the SQL query. The device may select a server from the plurality of servers based on applying the expression of the policy to content of the SQL query and forward the SQL query to the selected server via a second connection established between the device and the selected server.
