摘要： A method for maintaining server persistency, including: (a) receiving, by an intermediate entity, a first session request from client to receive a service from a server out of a plurality of servers that are connected to the intermediate entity; (b) selecting a server out of the plurality of servers and directing to the selected server information indicative of the first session request; (c) receiving a response of the selected server to the information indicative of the first session request; (d) analyzing the response of the selected server, to provide an analysis result indicative whether the response includes code to be executed by the client and includes at least one instruction that facilitates sending, by the client, another request, to receive a service from a server out of the plurality of servers; (e) modifying, based on the analysis result, the code by adding information that will cause the client to send a selected server identifier in association to the sending of the other request; and (f) sending a modified response to the client, wherein the modified response includes the modified code.
