libUrlFtpUploadFile - reuse open sockets?

[Jim Ault]

I think that using a callback handler you can detect the 100% complete  
message from the server,
then issue a 'QUIT' to close the connection immediately, then after  
getting the 'GOODBYE', start the next upload.

I have not done this in practice that I know of (accidents do happen  
and things work without you knowing why).
