How does a FTP server resume a download?
问题 I've been reading about the FTP protocol, but I cannot find in the protocol commands this feature that allows you to resume a partial download I have heard about. How does it work? is there any "range" protocol command that I cannot find? Cheers. 回答1: Resume is implemented using the REST command - see RFC 3659 来源: https://stackoverflow.com/questions/5678119/how-does-a-ftp-server-resume-a-download
