[vz-users] middleware errors out with "Unknown context: 'middleware.php'"

[Jens Scheidtmann]

Ok, found it:

I need to use "http://localhost" as middleware url in vzlogger.

I did not install apache2 nor nginx as proxy. Seems that although a
middleware.php file exists, this is not picked up by the php webserver and
that the proxy is supposed to do that mapping (once I read that section of
the install manual...)

I would have appreciated a warning in the german installation manual (
https://wiki.volkszaehler.org/software/middleware/installation)

Thanks for reading anyway, Jens
