head
Matches requests with HTTP method 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 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.
