cowboy/test/handlers/loop_handler_timeout_h.erl

%% This module implements a loop handler that sends
%% itself a timeout that will intentionally arrive
%% too late, as it configures itself to only wait
%% 200ms before closing the connection in init/3.
%% This results in a 204 reply being sent back by Cowboy.
