Types

type HeaderBasedSessionState

type HeaderBasedSessionState struct {

	// The name that will be used to obtain header value from downstream HTTP request or generate
	// new header for downstream.
	Name string `protobuf:"bytes,1,opt,name=name,proto3" json:"name,omitempty"`
	// contains filtered or unexported fields
}

This extension allows the session state to be tracked via request headers.

This extension encodes the address of the upstream host selected by the load balancer into a response header with the :ref:`header configuration <envoy_v3_api_msg_extensions.http.stateful_session.header.v3.HeaderBasedSessionState>`. When new requests are incoming, this extension will try to parse the specific upstream host address by header name. If the address parsed from the header corresponds to a valid upstream host, this upstream host will be selected first. See :ref:`stateful session filter <envoy_v3_api_msg_extensions.filters.http.stateful_session.v3.StatefulSession>`.

For example, if the header name is set to “session-header“, Envoy will prefer “1.2.3.4:80“ as the upstream host when the request contains the following header:

.. code-block:: none

session-header: "MS4yLjMuNDo4MA=="

When processing the upstream response, if “1.2.3.4:80“ is indeed the final choice the extension does nothing. If “1.2.3.4:80“ is not the final choice, the new selected host will be set to response headers (via the “session-header“ response header).

func (*HeaderBasedSessionState) Validate

func (m *HeaderBasedSessionState) Validate() error

Validate checks the field values on HeaderBasedSessionState with the rules defined in the proto definition for this message. If any rules are violated, the first error encountered is returned, or nil if there are no violations.

func (*HeaderBasedSessionState) ValidateAll

func (m *HeaderBasedSessionState) ValidateAll() error

ValidateAll checks the field values on HeaderBasedSessionState with the rules defined in the proto definition for this message. If any rules are violated, the result is a list of violation errors wrapped in HeaderBasedSessionStateMultiError, or nil if none found.

type HeaderBasedSessionStateMultiError

type HeaderBasedSessionStateMultiError []error

HeaderBasedSessionStateMultiError is an error wrapping multiple validation errors returned by HeaderBasedSessionState.ValidateAll() if the designated constraints aren't met.

func (HeaderBasedSessionStateMultiError) AllErrors

func (m HeaderBasedSessionStateMultiError) AllErrors() []error

AllErrors returns a list of validation violation errors.

func (HeaderBasedSessionStateMultiError) Error

Error returns a concatenation of all the error messages it wraps.

type HeaderBasedSessionStateValidationError

type HeaderBasedSessionStateValidationError struct {
	// contains filtered or unexported fields
}

HeaderBasedSessionStateValidationError is the validation error returned by HeaderBasedSessionState.Validate if the designated constraints aren't met.

func (HeaderBasedSessionStateValidationError) Cause

Cause function returns cause value.

func (HeaderBasedSessionStateValidationError) Error

Error satisfies the builtin error interface

func (HeaderBasedSessionStateValidationError) ErrorName

ErrorName returns error name.

func (HeaderBasedSessionStateValidationError) Field

Field function returns field value.

func (HeaderBasedSessionStateValidationError) Key

Key function returns key value.

func (HeaderBasedSessionStateValidationError) Reason

Reason function returns reason value.
