Has this parameter been changed in the current Version? I can not find it in the ignition.conf.  
Or is there another Way to use IIS as Reverse Proxy?  
I was able to setup IIS useing the Server Variable "HTTP\_SEC\_WEBSOCKET\_EXTENSIONS". So Perspective sessions can be desplyed. But the Ignition Designer is not working. I get the Error: "Unable to get the view config: View config is undefined."

You don't find it already in ignition.conf, you add it to the next available slot in the additional parameters section like his post shows.

I don't know if it will do anything for your issue though. Make sure you restart the Ignition Gateway after modifying ignition.conf.

Ok, I just added it and restarted the GW.  
But still same behavior. Do you have any guide about IIS setup as Reverse proxy?

No, but give support a call, maybe they've dealt with it before.
