// 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).
