in amahi 7 proxypass only works on generic webapps
this is mostly an informational bug. there should be a better architecture for this, however we do not have one yet.
the proxypass option only works in generic webapp mode, not custom.
more generally, apache options that go outside Directory directives do not work under custom options.
it does not work because in a custom webapp the APP_CUSTOM_OPTIONS are inserted inside the directory (see line 11) here
whereas in generic the APP_CUSTOM_OPTIONS are inserted outside the directory, which is proper and correct for proxypass
so this is something we have to deal with .. it's not a completely customized solution for webapps.
whatever we did, it was done for a reason at some point or another ...
