Problems with visible/unique hostname

Hi,

we are using two Squid proxies via DNS round-robin.
Both Squids share the name proxy.draeger.com and have the
unique name "proxy1" and "proxy2". I tried to enable the
"visible" and "unique name" feature in the squid.conf, to hide
the real-names against the users. But now I get an error in the
cache.log while using ftp:

1999/11/02 15:58:08| internalStart: unknown request:
GET /squid-internal-static/icons/anthony-compressed.gif HTTP/1.0
Referer: ftp://ftp.funet.fi
Connection: Keep-Alive
User-Agent: Mozilla/4.7 (WinNT; I)
Pragma: no-cache
Host: proxy.draeger.com:8080
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/png
Accept-Encoding: gzip
Accept-Language: de,en
Accept-Charset: iso-8859-1,*,utf-8
Authorization: Basic

The browser show's the "broken_image" instead of the real
internal-icons.

Regards,
        Matthias
