Hi @all, has someone successfully realized an WMS with UTF-Grid-Layer? (http://mapserver.org/development/rfc/ms-rfc-93.html)
I use Mapserver 7.0.0 (and also tried the latest master) and wasn't able to get any output from the web-Service as WMS-Request with format "application/json". The application/json-response has a filesize of 0Bytes, other formats (jpeg/png) work well - with exactly the same request, except the format. UTF-Grid also seems to be produced well with a simulated request against mapserver on the commandline-interface ("/usr/local/bin/mapserv QUERY_STRING="SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=339444,5697190,347678,5702286&CRS=EPSG:25832&WIDTH=1556&HEIGHT=963&LAYERS=poi &STYLES=&FORMAT=application/json&TRANSPARENT=TRUE&map=PATH_TO_MAPFILE" > OUTPUT") Mapserver LOG (DEBUG 5) with wms request: [Wed Mar 2 14:47:17 2016].978816 CGI Request 1 on process 23097 [Wed Mar 2 14:47:17 2016].978943 msDrawMap(): rendering using outputformat named UTFGRID (UTFGRID).

Some further investigation showed me, that the correct output is written to the apache error.log!!! I'm not a developer of web application/cgi etc, but comparing this to writing shell scripts (which I do a lot), it seems, that the mapserver output for format "application/json" goes to "STDERR" (apache error.log) and not to "STDOUT" (client) System is debian7, apache 2.2, mapserver 7/master (self compiled, as well as the geos-/gdal-/proj-stack). Could someone crosscheck this feature, does it need special apache-config? Is it a misconfiguration of apache or a mapserver/apache-bug? Any ideas out there?
