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 *durationpb.Duration `protobuf:"bytes,2,opt,name=ttl,proto3" 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"`
	// contains filtered or unexported fields
}

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-v3/config/route/v3/route.proto#envoy-api-msg-route-routeaction-hashpolicy-cookie

func (*Cookie) Clone added in v1.8.24 

func (m *Cookie) Clone() proto.Message

Clone function

func (*Cookie) Descriptor deprecated 

func (*Cookie) Descriptor() ([]byte, []int)

Deprecated: Use Cookie.ProtoReflect.Descriptor instead.

func (*Cookie) Equal 

func (m *Cookie) Equal(that interface{}) bool

Equal function

func (*Cookie) GetName 

func (x *Cookie) GetName() string

func (*Cookie) GetPath 

func (x *Cookie) GetPath() string

func (*Cookie) GetTtl 

func (x *Cookie) GetTtl() *durationpb.Duration

func (*Cookie) Hash deprecated added in v1.2.13 

func (m *Cookie) Hash(hasher hash.Hash64) (uint64, error)

Hash function

Deprecated: due to hashing implemention only using field values. The omission of the field name in the hash calculation can lead to hash collisions. Prefer the HashUnique function instead.

func (*Cookie) HashUnique added in v1.18.0 

func (m *Cookie) HashUnique(hasher hash.Hash64) (uint64, error)

HashUnique function generates a hash of the object that is unique to the object by hashing field name and value pairs. Replaces Hash due to original hashing implemention only using field values. The omission of the field name in the hash calculation can lead to hash collisions.

func (*Cookie) ProtoReflect added in v1.6.0

type HashPolicy 

type HashPolicy struct {

	// Types that are assignable to KeyType:
	//
	//	*HashPolicy_Header
	//	*HashPolicy_Cookie
	//	*HashPolicy_SourceIp
	KeyType isHashPolicy_KeyType `protobuf_oneof:"KeyType"`
	// If set, and a hash key is available after evaluating this policy, Envoy will skip the subsequent policies and
	// use the key as it is.
	// This is useful for defining "fallback" policies and limiting the time Envoy spends generating hash keys.
	Terminal bool `protobuf:"varint,4,opt,name=terminal,proto3" json:"terminal,omitempty"`
	// contains filtered or unexported fields
}

Specifies an element of Envoy's hashing policy for hashing load balancers
