I'm a newbie , my question is basic but i'm blocked by this .
Please help me , i have to defend Delegate's solution in my organisation
and the first step is to responds to this demand (with a ftp - or http -
cache tree structure , how to be sure that the files modifications are
propagating immediately and only this , the others files , not modified
, reached on the proxy ) .
I use a delegate 7.9.5 and with this option , the proxy delegate used in
give with this command (launched on a lan machine ):
/delegate7.9.5/src/delegated -v -P21 SERVER="ftp://www.annuwave
.net/" EXPIRE=0 ADMIN="email@example.com"

06/09 10:18:29.29  1+0/22: FTP-CACHE: written=1 531 bytes
This seems indicate that when i have EXPIRE=0 on my command , the
delegate go automatically on the server even if the file is not modified
( because the parameter controlled is the validity of the cache , with 0
i can't use the cache because it is considered always like expired ).
My purpose is the following
I have a server ftp on internet , reachable by RTC .
My delegate is running on an intranet , who share the rtc line .
I'm interested to have a proxy for ftp ( ftp command line ) .
Because of course the lan is faster than rtc .
But if a file is modified on the server , what is the command to
propagate this modification on the proxy ( and only this modification )
Thanks you very much for any clue , my first questions wasn't very clear .
