A client can generate a session key that can be used for at least two things. First, a load balancer can be selected by the client using the session key by using a consistent or deterministic hashing algorithm so that the same load balancer is selected from a set of weighted load balancers. After selecting the load balancer, the client can send the request to the selected load balancer. The load balancer then uses the same session key, which can be transmitted in an HTTP header, to select a backend host server computer. The result is that session affinity is maintained."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Maintaining client/server session affinity through load balancers","description":"In one embodiment, a system uses a two-layer deterministic function, such as a hashing mechanism, to ensure session stickiness or affinity.
