I tried this under XP with VM but, it didn't started. :(

There is no cross specification of HTTP and FTP which would allow the two to interact. Someone, somewhere, would have to download, and then upload it.

If you have shell access to the web server, the easiest way would be to upload it directly from the webserver to the ftp server with the ftp command (Assuming it's a *nix server.)

If you have shell access to the ftp server, then you could also use the wget command to download the file directly to the ftp server, again assuming it's a *nix server.
