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

[Ying Xu]

Hi Seb,

Thanks for the info. The client browser opens properly with "--authKey", 
"${secret}" removed.

=>  "sessionURL" :  "ws://192.168.120.8:${port}/proxy?sessionId=${id}"
${port} should be there otherwise  "pvpython pv_web_visualizer.py" is 
not issued.

Thanks!

Ying
