Azure Container Apps now supports session affinity, also known as sticky sessions, for HTTP-based workloads. This feature is in public preview.
Session affinity enables you to route all requests from a single client to the same Container Apps replica. This is useful for stateful workloads that require session affinity.
Container apps in single revision mode support session affinity. When enabled, Container Apps automatically adds a cookie to HTTP responses to track the replica being used by the client.
