Every App can include a mod_proxy configuration. By default every App get its own apache namespace via mod_proxy.


After installing the jenkins app following error messages appears in "fqdn/jenkins/manage":
"It appears that your reverse proxy set up is broken." 
According to [1] this can be fixed with the options "nocanon" & "AllowEncodedSlashes NoDecode" in the virtualHost reverse proxy entry.

Full configuration:
<VirtualHost *:80>
        Include /etc/apache2/ucs-sites.conf.d

        ProxyPass /jenkins/ http://127.0.0.1:40001/jenkins/ nocanon retry=0
        ProxyPassReverse /jenkins/ http://127.0.0.1:40001/jenkins/
        AllowEncodedSlashes NoDecode
</VirtualHost>

So, it would be nice to get this configurable.
