What is the URL in the SFTP case?
Then I get below result in my console: ftp: 257 "/home/user_name" is current directory. sftp: 257 "/" is current directory.
Surely sftp didn't mention 257?
But if I manually login to the remote server by ftp/sftp, then type "pwd", I get "/home/user_name" as current dir for both cases.
With libcurl you don't "login" to the site the same way your other clients may and I think that adds to the confusion.
With libcurl you specify a URL to libcurl and that includes (an implied or explicit) directory. Directory treatment of URLs is quite different in FTP compared to SFTP URLs. In FTP you get the user's home directory by default if you don't explicilty ask for an absolute directory, in SFTP you get the root directory by default unless you explicilty ask for the user's home directory.
