              want to use paraview web with SSL. As far as I understand

              possible with pvpython?

            <div>

            </div>
            <div>It might be possible with pvpython, but I've never done
              it, I've always used apache to rely on a single opened
              port and handle the encryption. </div>

            <div>If pvpython directly support the wss connection, you
              can be good. Usually the setup, that I do is that I have
              Apache serving only the port 443 (https) for both the
              static content and the (wss) websocket endpoint. And I use
              a mapping file between the Websocket endpoint that get
              returned by my launcher and the host/port I should connect
              to on the backend to establish the link between the client
              and the actual ParaViewWeb server instance.</div>
            <div>

            </div>
            <div>But that does not mean, that's the only way to do it
              and if you don't mind having several port open, I don't
              see why it could not work.</div>

            <div>Well, I guess I haven't tried to run the new Visualizer
              server on a Windows machine. </div>
            <div>But with ParaView 5.2 (yet to be released), we should
              have a ParaViewWeb back in the binaries. So we should make
              sure our Visualizer command line tool work on that
              platform as well.</div>
            <div>Although, the command line is more for beginners than
              anything else as it only simplify the demo usage. In real
              word deployment, with a launcher, the true pvpython
              command line should be used instead.</div>
