[X2Go-User] testing session broker in WSGI/plain/inifile configuration

[Short, Kermit]

OK made a bit of progress.  I've got the session profile defined in the config file, and I'm getting the x2go client to communicate with the session broker.  It seems though, that things are breaking when the session broker tries to communicate with the broker agent.

I get an internal server error console message on the terminal where I'm trying to launch x2goclient.  When I look in the apache logs, I see the following error from the virtual host for the wsgi session broker:

<VirtualHost *:443>

Do I have to actually modify something in the broker agent's configuration?  What might I have done wrong in a configuration file on the session broker server?

Thanks!!!

Enable X2GOBROKER_DEBUG in the wsgi config. The X2Go Client does those
queries with POST requests. If you enter that URL into your browser,
the browser does a GET request. GET requests are only enabled in
X2GOBROKER_DEBUG=1 mode.
