Apache proxy fix to handle http issue from browser
Since the frontend (https://missingosm.geog.uni-heidelberg.de) is running on secure network but server not (http://deepvgi.geog.uni-heidelberg.de:3010/), browser is not making any request to this insecure server. To fix it edit the apache file of Missingosm server (mzia@gisservices.geog.uni-heidelberg.de) with the following two lines just before </VirtualHost>
in the file /etc/apache2/sites-available/000-default.conf
ProxyPass /api http://deepvgi.geog.uni-heidelberg.de:3010
ProxyPassReverse /api http://deepvgi.geog.uni-heidelberg.de:3010
This will replace http://deepvgi.geog.uni-heidelberg.de:3010/
with https://missingosm.geog.uni-heidelberg.de/api/
