Hope I didn't leave the impression that it's wrong to use VNC through a
HTTP proxy...
It's just that the particular firewall tunneling method that has to be
used for restricted Java applets, requires a http POST requests whenever
there's data to be send from client to server, imposing huge workloads
on a http proxy with VNC.
I know little about httptunnel, but I can guess what it does, and tail
my proxy logs while using it.
httptunnel, will just use 1 GET and 1 POST requests for all data both
ways, so the overhead will be low, and the're won't be a lot of logging
to do for a http proxy. So using it with VNC is OK.
However: setting a buffersize with httptunnel (when using a buffering
http proxy) will get you multiple POST requests for sending data = more
overhead. So you should only set a buffer when your http proxy requires
this.
Using httptunnel with a buffering http proxy with VNC is not a good
idea, IMHO.
