Hi Othmar The same behaviour here with squid 3.5.5: # Catching an existing file results in a correct 200: $ curl -x proxy:3128 -I ftp://mirror.switch.ch/README HTTP/1.1 200 OK Server: squid Mime-Version: 1.0 Date: Wed, 01 Jul 2015 07:58:28 GMT Content-Type: text/plain Last-Modified: Wed, 05 Dec 2007 14:13:16 GMT X-Cache: MISS from proxy Connection: keep-alive # Catching an non-existing file hangs for a unknown time $ curl -x proxy:3128 -I ftp://mirror.switch.ch/README123 I can confirm, that with older squids (< 3.5) catching a non-existing-file with ftp gives back a correct 404.
