The java vncviewer will not use the browser configured proxy (for
590x/rfb) anyway, and it can not be configured to do so at all.
I have been working on a Java vncviewer that does transparently use the
browser configured proxy (and that should work with proxy authentication
also).
It tunnels rfb (or any tcp-layered protocol) over http with
java.net.URLConnection instead of java.net.Socket. A http-tunnel-server
forwards the connection to the vnc-server. I have taken security issues
with this into account for the next release.
But here's my problem: a http proxy will log all http requests, and with
rfb that means a lot. It's not just that a mousemove or a keystroke will
already generate several http requests (a bit of buffering will help
there). But the viewer will request a framebuffer-update whenever it is
ready to receive data, and for things like blinking cursors that is once
every second or so. It just wouldn't be right to put such strain on a
http proxy. Socks is OK though.
Anyway, the next release will not include a Java VNCviewer for this
reason:-( I switched to telnet and SSH.
Off course there's other firewall tunneling equipment, that does not
have the problems a restricted Java applet has:

http://www.htthost.com/
http://www.totalrc.net/s2h/
http://www.mokabyte.it/2000/06/firewallutil.htm
http://www.mindbright.se/mindterm/ is also proxy-aware, but used as an
applet, it requires permission to connect to the proxy-host.
I will not notify the list for the next release, because it will no
longer be related to VNC. I will keep my other http-proxy java
vncviewer, that is only useful in particular circumstances (and does not
support proxy authentication), at the old location:
http://www.workspot.net/~harmen/vnc/
Will keep reading the list though:-) And have been trying some other
trick that works with my Squid, but is just too weird to be included in
what I would like to become a respectable package eventually;-) I will
be focussing my efforts on that one though, once I finish the next
release.
