[Paraview] paraview web issues "authentication error" in browser.

[Sebastien Jourdain]

Hi Ying,

instead of pipeline, it should be Visualizer, but I've also noticed
something strange in your launcher config.

=>  "sessionURL" :  "ws://192.168.120.8:${port}/proxy?sessionId=${id}"

Why do you have ${port} here is you are using apache to forward the web
socket?

Another thing that you can do is remove all the [ "--authKey", "${secret}"
] inside the "cmd" sections.
