I have just run into this problem myself.

What follows is a diff for ftpget 1.1.20. It fixes this problem, as
well as one where Squid drops the password from the BASE tag it returns
to the browser. Dropping the password doesn't cause problems for
Netscape, but it confuses Internet Explorer.

There may well be a better way of fixing this second problem. I just
started looking at the source yesterday, so I might have missed a
glaringly obvious fix.
