designed to work. If it received the request for the target not cached, then it will fatch that file automatically even the client has canceled the request. Then the second or later requests will be served with that cached file instead to save bandwith. For small files, the late request will see very fast transfer. Only with large files you would be able to see the speed will go down as the cache server is doing the transferring.
