40265 - [RFE] Allow 'Append' or 'Continue' option in FTP download

Status: VERIFIED DUPLICATE of bug 18004

(Core Graveyard :: Networking: FTP, enhancement, P3)

Description

[gabriel]

If an FTP download detects that the local file already exists, it should prompt
the user for an 'Append' or 'Continue' option, as well as 'Overwrite'. The
'Append/Continue' would skip over the part already there and download the rest.
(I.E. similar to the -c option in wget). This would be very useful in the case
of crashes/accidental cancels. I can't believe this functionality was never
added to Netscape !

I suppose the 'Cancel' option for FTP downloads would also need changing. When
you clicked cancel, it would prompt you whether to delete the local file or not.
That way, if an FTP server suddenly froze you could cancel the download, elect
to leave the local file there, go to a mirror site, and continue the download
from the mirror site.

FTP needs to support byte range requests via the AsyncRead() api (underneath it 
needs to implement the REST command).

Please don't forget about the other bit 'Cancel and leave file'. That makes this
function many times more useful.
