4.1.2.5 Data Connection Management: RFC-959 Section 3.3 |
A User-FTP that uses STREAM mode SHOULD send a PORT command to assign a non-default data port before each transfer command is issued.
This is required because of the long delay after a TCP connection is closed until its socket pair can be reused, to allow multiple transfers during a single FTP session. Sending a port command can avoided if a transfer mode other than stream is used, by leaving the data transfer connection open between transfers.
