Types 

type Cookie struct {
	// required, the name of the cookie to be used to obtain the hash key
	Name string `protobuf:"bytes,1,opt,name=name,proto3" json:"name,omitempty"`
	// If specified, a cookie with the TTL will be generated if the cookie is not present. If the TTL is present and zero, the generated cookie will be a session cookie.
	Ttl *time.Duration `protobuf:"bytes,2,opt,name=ttl,proto3,stdduration" json:"ttl,omitempty"`
	// The name of the path for the cookie. If no path is specified here, no path will be set for the cookie.
	Path                 string   `protobuf:"bytes,3,opt,name=path,proto3" json:"path,omitempty"`
	XXX_NoUnkeyedLiteral struct{} `json:"-"`

	XXX_sizecache        int32    `json:"-"`
}

Envoy supports two types of cookie affinity: - Passive: Envoy reads the cookie from the headers - Generated: Envoy uses the cookie spec to generate a cookie In either case, the cookie is incorporated in the hash key. additional notes https://www.envoyproxy.io/docs/envoy/latest/api-v2/api/v2/route/route.proto#envoy-api-msg-route-routeaction-hashpolicy-cookie
