Yes, in the meantime I got some request parameters but sadly they do not work yet for jupyter.
The problem is that to connect to jupyter, I need more than
one redirect at the same time: I need the path "/" to use https and I need the
path "/api/kernels/" to use wss, while the reverse proxy for "/api/kernels" needs
to use https again. With plain apache, the only configuration which works for me is the
one I wrote in the very first post of this thread in "apache_custom_http". Then Rafael
wrote that apache_custom_http is not allowed in vifib for security reasons. This is why
tried now to convert the working configuration into apache frontend request parameters
only by using "url" and "path" parameters, but I don't know how to
use several "url" and several "path" parameters in the same request. Rafael then
wrote in the third post of this thread "I think you can request several slaves for
the same thing, and using url and path parameters.". This is why I asked, if
there is a document how to achieve this.
