VNC through HTTP proxy

[Harmen van der Wal]

Just started using VNC, browsed the archives, and joined the mailing
list, so sorry if I'm stating the obvious.

I couldn't connect to Workspot through a client-side packet filtering
firewall. I guess it would be easy to reconfigure, but I didn't bother
asking my ISP;-)

In such cases I always use a HTTPort-like program, to get a local mirror
of the service, and connects to the actual service via a
free-internet-HTTP-proxy, requesting a SSL with "connect host:port
HTTP/1.0". The free-internet-HTTP-proxy is beyond the firewall, so
problem solved:-)

Usually HTTPort is used by those who only have web-access through a HTTP
proxy, and still want to access mailservers, news, or whatever TCP based
service outside the local net. It can also be used for VNC, since that's
also TCP based (haven't tried though).

Anyway: I modified the Java Viewer to allow such connections through a
common web caching HTTP proxy (up to 2 actually).

It is available for anyone who can use it, along with some further
reading. Since some HTTP proxies allow for an applet to get the proxy as
it's codebase, you can test it without adjusting your Java Security
settings.
