.. _-head-:
head
====
Matches requests with HTTP method ``HEAD``.
Signature
---------
.. includecode2:: /../../akka-http-scala/src/main/scala/akka/http/scaladsl/server/directives/MethodDirectives.scala
:snippet: head
Description
-----------
This directive filters the incoming request by its HTTP method. Only requests with
method ``HEAD`` are passed on to the inner route. All others are rejected with a
``MethodRejection``, which is translated into a ``405 Method Not Allowed`` response
by the default :ref:`RejectionHandler <The RejectionHandler>`.
.. note:: By default, akka-http handles HEAD-requests transparently by dispatching a GET-request to the handler and
stripping of the result body. See the ``akka.http.server.transparent-head-requests`` setting for how to disable
this behavior.
