Ok, after removing my /index.html AND using that rewrite rules, I finally get the catalog landing page \o/

But I do not agree with you. QGIS should not force a server to run on / to be able to use/see the catalog page, not even in prototypes/dev environments.
With me for example I always have several other projects (sometimes also needing /) on my machines/laptops.
Most often I want the html/client to start on / and a map/geo/qgisserver is more of a help application...

So contrary to my complaint of the many VARS, I would be in favor or a SERVER_BASE_PATH or so....

(now building master server on my little homeserver to be able to show some things to you/others... but that one I really cannot serv stuff on / ...)

Is there some caching going one? I still get strange results like:

- When using QGIS_SERVER_LANDING_PAGE_PROJECTS_DIRECTORIES, I do have the landing page on
http://localhost/index.html#/
but then the http://localhost/wfs3 only shows me only the data of the project file I have defined with QGIS_PROJECT_FILE

EVEN if I see the right 4 maps on the catalog page, if I go the the metadata/services/wfs3 I do NOT get the WFS data of that map, but then it seems one of the other (I have 4 maps/projects) always opens, though I see different identifiers like "3286a1aa4483079c3539955ea38f1bd9' below"

I also see:

http://localhost/index.html#/map/3286a1aa4483079c3539955ea38f1bd9
Epic failure
JSON.parse: unexpected character at line 1 column 1 of the JSON data

Is there some heavy caching I should/can invalidate?

Also sometimes I miss 3 (of the 4) map previews... As if there are no requests going. Especially when I zoom in in those thumbnails. If I pan after that the map appears most of the times.


I hope others also start testing (preferably with apache :-) ), I do hope these are not personal issues I have with QGISserver....

PS: the actual source of all this was a question of another community aspirant QGISserver user, trying to setup QGISserver... 
it's just that I can be rather pitbully when I do not get something to work when I think it should be possible (or others tell me they have) ....
