Daily Term: Sticky Sessions

Sticky Sessions

Sticky Sessions, or session affinity, ensure that all requests from a user during a session are routed to the same server in a load-balanced environment. For example, a load balancer might route a user’s requests to Server A, where their session data is stored locally, to avoid fetching it from a shared store. Sticky sessions simplify session management but can lead to uneven load distribution and issues if a server fails.
