what is the best method for downlading a file from a server to a client through internet.
the connection must be secure and the download must be initiate after the client login.

wich language or solution do you recommend me ?


thanks in adavance for you help


anouk

Are you looking for a commercial or free solution?
What operating system for the client and server?
Any constraints or limitations on ports/protocols?
What size is the file?
Does the transfer need to be automated or will there be a human establishing the connection and starting the transfer?
How much bandwidth (throughput of the Internet connection) do you have available?

I prefere a free solution.

The client use Windows and the serveur is Unix.

For the moment we have not constraint for the ports and the protocols.

The files will be compressed and the size will be smaller than 5 MB.

The transfert must be automated.

For the bandwith, it's depends of the user modem and configuration..

thanks :-)

Probably the best solution is to purchase a certificate and use SSL. However, you can also attempt encoding the file with PGP or performing the transfer through SSL. I have done the former, but not the latter.
