        Sends a single file to the remote host. filename may contain a relative path specification. When this is the case, sendFile will attempt to create any necessary parent directories before sending the file. The file will then be sent using the entire relative path spec - no attempt is made to change directories. It is anticipated that this may eventually cause problems with some FTP servers, but it simplifies the coding.
