If the service returns the fallthrough response, the request is resubmitted
as a GET. The resulting response's body is killed, but all headers are
preserved. This is a naive, but correct, implementation of HEAD. Routes
requiring more optimization should implement their own HEAD handler.
Handles HEAD requests as a GET without a body.
