When you send a file by HTTP, web browsers send the total file size in the http header.
Do you think it\'s the same with the FTP protocole?

FTP has a number of transfer modes, but none of them send the entire length of the file beforehand. You can see them all in RFC 959, section 3.4.
Note that the SIZE command defined in RFC 3659 is purely for downloads, not uploads.
