Passive mode

Please can someone explain the significance of selecting passive mode when
connecting with FTP in VS 2005 or 2008
Is selecting it likely to prevent VS2008 repeatedly downloading he same
files when I change page?
Jaezftp use two tcp/ip connections, one for traffic each way. in active (the
original ftp mode) the client opens one, and the server opens the other.
this required the client to have a port open thru the firewall, so
passive mode was added. in this mode the client opens both connection to
the server. after the connections are established, there is no difference.

Technically, the two ports are for "command" and "data" and are not
directional. But yes, passive mode allows the client to initiate both
connections which alleviates many firewall issues. Selection of "passive"
mode has no effect beyond establishing the "data" connection (assuming, of
course, that both client & server support passive mode).
