    public final class HeaderBasedSessionState
extends com.google.protobuf.GeneratedMessageV3
implements HeaderBasedSessionStateOrBuilder
     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).
