  It can, but by using the FTP SITE command to sneak then through. And
since it's a site specific implementation, changing ACLs on a VMS FTP server
will most likely be different changing ACLs on a UNIX FTP server.

  HTTP/1.1 can serve multiple requests on a single session; in fact, for
HTTP/1.1 that's the default connection type.
