Hello Yuri,

Thanks for your quick reply.
The ACL you suggested will probably solve the problem.

Nevertheless I'm not sure that this is working as intended as the memory
used by Squid is constantly increasing and not settling after a while.
How does range_offset_limit is relevant for FTP requests?
quick_abort_min does not make any sense for me as there are no aborted
requests in my test case.

It seems more that Squid generates the index.html when I do a wget
ftp://foo.bar/pub/ and does not free the cached object later on.

Just for the records, the memory footprint of the process serving the
FTP request is 10 times higher than the one of Squids processing normal
web traffic at a high request rate.
