You apply multiple applet parameters in the regular way, e.g.:
https://far-away.east:5900/?GET=1&urlPrefix=mysubdir&...
Router/Firewall port redirs: If you are doing port redirection at
your router to an internal machine running x11vnc AND the internet
facing port is different from the internal machine's VNC port, you
will need to apply the PORT applet parameter to indicate to the applet
the Internet facing port number (otherwise by default the internal
machine's port, say 5900, is sent and that of course is rejected at
the firewall/router). For example:
https://far-away.east:443/?GET=1&PORT=443
(actually, in this case the first ":443" isn't needed because that is
the default port for https; it would be needed for any other port). So
in this example the user configures his router to redirect connections
to port 443 on his Internet side to, say, port 5900 on the internal
machine running x11vnc.
To configure your router to do port redirection, see its instructions.
Typically, from the inside you point a web browser to a special URL
(e.g. http://192.168.1.1) and you get a web interface to configure it.
Look for something like "Port Redirection" or "Port Forwarding",
probably under "Advanced" or something like that. If you have a Linux
or Unix system acting as your firewall/router, see its firewall
configuration.

Enhanced TightVNC Viewer (ssvnc: SSL/SSH VNC viewer)
[1](To Downloads) [2](To Quick Start)
The Enhanced TightVNC Viewer package started as a project to add some
patches to the long neglected Unix TightVNC Viewer. However, now the
front-end GUI and wrapper scripts features dwarf the Unix TightVNC
Viewer patches (see the lists below).
It adds a GUI for Windows, Mac OS X, and Unix that automatically
starts up a STUNNEL SSL tunnel for SSL or SSH connections to
[1]x11vnc, and then launches the TightVNC Viewer to use that tunnel.
It also enables SSL encrypted VNC connections to any other VNC Server
running an SSL tunnel, such as STUNNEL, at their end. It can be used
to perform SSH connections to any other VNC Server as well. The tool
starts up STUNNEL SSL tunnel for SSL or SSH connections to [3]x11vnc,
and then launches the TightVNC Viewer to use the tunnel. It also
enables SSL encrypted VNC connections to any other VNC Server running
an SSL tunnel, such as STUNNEL, at their end. It can be used to
perform SSH tunnelled connections to any VNC Server as well. The tool
has many additional features (see below for a list).

Important Note for Windows Vista: One user reports that on Windows
Vista if you move or extract the "ssvnc" folder down to the "Program
Files" folder you will be prompted to do this as the Administrator.
But then when you start up ssvnc, as a regular user, it cannot create
files in that folder and so it fails to run properly. We recommend to
not copy or extract the "ssvnc" folder into "Program Files". Rather,
extract it to somewhere you have write permission (e.g. C:\ or your
User dir) and create a Shortcut to ssvnc.exe on the desktop.
If you must put a launcher file down in "Program Files", perhaps an
"ssvnc.bat" that looks like this:

Important Note for Windows Vista: One user reports that on Windows Vista
if you move or extract the "ssvnc" folder down to the "Program Files"
folder you will be prompted to do this as the Administrator. But then
when you start up ssvnc, as a regular user, it cannot create files in
that folder and so it fails to run properly. We recommend to not copy
or extract the "ssvnc" folder into "Program Files". Rather, extract
it to somewhere you have write permission (e.g. C:\ or your User dir)
and create a Shortcut to ssvnc.exe on the desktop.
If you must put a launcher file down in "Program Files", perhaps an
"ssvnc.bat" that looks like this:
C:
cd \ssvnc\Windows

-httpsredir [port] In -ssl mode with the Java applet retrieved via HTTPS:
when the HTML file containing applet parameters
('index.vnc' or 'proxy.vnc') is sent do not set the
applet PORT parameter to the actual VNC port but set it
to "port" instead. If "port" is not supplied, then
the port number is guessed from the Host: HTTP header.
This is useful when an incoming TCP connection
redirection is performed by a router/gateway/firewall
from one port to an internal machine where x11vnc is
listening on a different port. The Java applet needs to
connect to the firewall/router port, not the VNC port
on the internal workstation. For example, one could
redir from mygateway.com:443 to workstation:5900.
This spares the user from having to type in
https://mygateway.com/?PORT=443 into their web browser

be explicity indicated: https://mygateway.com:8000/...)

.IP
In \fB-ssl\fR mode with the Java applet retrieved via HTTPS:
when the HTML file containing applet parameters
('index.vnc' or 'proxy.vnc') is sent do not set the
applet PORT parameter to the actual VNC port but set it
to "port" instead. If "port" is not supplied, then
the port number is guessed from the Host: HTTP header.
.IP
This is useful when an incoming TCP connection
redirection is performed by a router/gateway/firewall
from one port to an internal machine where x11vnc is
listening on a different port. The Java applet needs to
connect to the firewall/router port, not the VNC port
on the internal workstation. For example, one could
redir from mygateway.com:443 to workstation:5900.
.IP
This spares the user from having to type in
https://mygateway.com/?PORT=443 into their web browser
(note 443 is the default https port; other ports must
be explicity indicated: https://mygateway.com:8000/...)
