Hallo,

on my webplattform (myownserver.com/calling server) I have some prob concerned with an API-Call (REST-Url).
It's a plattform e.g. addressed to learners of a computer language. on a particular HTML-input-formular
learners are supposed to paste in a source code snippet. By Clicking on an "OK"-Button of the formular
the snippet wil be sent to another server with a JUNIT Environment. The results of the UNIT-test
are transferred back to the calling server and are displayed on the aforementioned formular.

Unfortunately the Call to the JUNIT Server does not work. It does not reach the JUNIT-Server.
After Clicking on the ok Button the browsers displays a grey site mit the following error
message (little translation from German).

This site does not work

myownserver.com kann cannot process this request.

Of interest is IMHO the part at the end, where the error code
"Response sent with status 500" is logged.
Before the Apache-Module "authz_core" coms into play. The authorisation process does not seem to work the
way I want it to:
"request authorized without authentication by access_checker_ex hook"

I just want to enable the the API-Call
So what can I do ?
Conf-settings ?
How can I configure the authz_core-Module in order to allow the call ...
other the steps ? Directory settings ?
How can I start here ?

Any help, how to etc on this would be super !

Thanks in advance for your help!

Please post the config for it. 500 is most often a configuration error.
