Re: [squid-users] Squid FTP - CWD direct vs incremental

I'd just like to add that FreeBSD went through this discussion a while ago
and it surfaced that there's occasional "broken" servers (and I couldn't
remember if they covered frequency or type of server!) which can't handle
CWD into a path but can handle it per-directory. I forget the reasonings
but I'm sure you can dig it out of mailing list archives.
