	// Client affinity lets you direct all requests from a user to the same endpoint,

	// the client request. Clienty affinity gives you control over whether to always
	// route each client to the same specific endpoint.
	//
	// AWS Global Accelerator uses a consistent-flow hashing algorithm to choose
	// the optimal endpoint for a connection. If client affinity is NONE, Global
	// Accelerator uses the "five-tuple" (5-tuple) properties—source IP address,
	// source port, destination IP address, destination port, and protocol—to
	// select the hash value, and then chooses the best endpoint. However, with
	// this setting, if someone uses different ports to connect to Global Accelerator,
	// their connections might not be always routed to the same endpoint because
	// the hash value changes.
	//
	// If you want a given client to always be routed to the same endpoint, set
	// client affinity to SOURCE_IP instead. When you use the SOURCE_IP setting,
	// Global Accelerator uses the "two-tuple" (2-tuple) properties— source (client)
