Squid is an HTTP proxy, not an FTP proxy. When a web browser is
configured to use a proxy it uses HTTP to the proxy which then gateways
the request to FTP.

This is microsofts way of saying that MSIE do not support FTP uploads
via HTTP proxies, and that you need to use a SOCKS proxy if you need
these functions..

btw, Squid do support FTP uploads if the client cares to try..

For real FTP clients needing to talk the FTP protocol you should use
either SOCKS or an FTP proxy.
