[DUG] Indy FTP problem

[Leigh Wanstead]

Hi David,

What I did is create the ftp component on the fly. Of course there is
exception handling logic to handle the error. Once finished the work, the
ftp component was destroyed. The overhead of creating and destroying ftp
component can be ignored compare to slow network connection. My
understanding is the time to create and destroy ftp component is faster than
100mbps network connnection.

By create and destroy ftp component, there is no error status left to be
uncertain, thus no error can stop next time ftp talking.

I understand that viewpoint. This app uploads a number of files
(unknown) to the server on completion of some other processing. What
happens if the server goes away during this upload?

Hi David,

Here is what I will do.

I will not stay idle while connect to ftp. I will start transaction if I
have something to do i.e. get a file, put a file. Once finish what I
want, I
will disconnect immediately from the ftp server.

All network connections are valuable and limited resource which should
be
shared.

Just my 2cents

I'm having a problem with FTP in one of my apps. (First time with an FTP
client).

Using Indy 10 on 2005.

If the server times out (broken Internet connection or whatever), the
client never knows, and if the user attempts to do something, an error
occurs. I can trap the error, but I can't work out what to do to reset
the idFTP component. Disconnect, quit and anything else I can think of
just keep throwing errors.

I can easily test this by shutting down my FTP server when the client is
connected.

Any ideas?

Regards,
David O'Brien
