query raster layer

[Giorgio Libertà]

Dear Frank,

Thank you for your replay.
For the moment I can not give you access to this part because I am 
developing
this new functionality and the all stuff is on my intranet. Sorry.

But anyway to give you more info:
1. I am using mapserver 4.8.3 with GDAL 1.2.6
2. the url  example is 
dev-effis.h07.jrc.it/mapserv/WmsEffis?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&LAYERS=landcover&QUERY_LAYERS=landcover&FEATURE_COUNT=100&BBOX=-7.366837147853632,32.29370224938404,10.613480010522485,50.02771369326186&WIDTH=730&HEIGHT=720&X=192&Y=488&INFO_FORMAT=text/html
3. when I use the GetCapabilities the layer 'landcover' is queryable=1

thx & ciao
