[mapserver-users] GetFeatureInfo Cascading WMS

[Berger, Cora]

Dear group,
normally it is possible to request more than one layer with one GetFeatureInfo-request. This doesn't work with cascading WMS. Is this a bug?

Here are some example request:

Query-Layer: nw_tim_h_inu (works fine)
https://www.wms.nrw.de/geobasis/wms_nw_tim?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetFeatureInfo&FORMAT=image/png&TRANSPARENT=true&QUERY_LAYERS=nw_tim_h_inu&LAYERS=nw_tim_h_inu&INFO_FORMAT=text/html&RADIUS=10&I=50&J=50&CRS=EPSG:25832&STYLES=&WIDTH=101&HEIGHT=101&BBOX=379495.5134930965,5625172.894819761,380460.5309751969,5626137.912301861

Query-Layer: nw_tim_m_inb (works fine)
https://www.wms.nrw.de/geobasis/wms_nw_tim?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetFeatureInfo&FORMAT=image/png&TRANSPARENT=true&QUERY_LAYERS=nw_tim_m_inb&LAYERS=nw_tim_h_inu&INFO_FORMAT=text/html&RADIUS=10&I=50&J=50&CRS=EPSG:25832&STYLES=&WIDTH=101&HEIGHT=101&BBOX=379495.5134930965,5625172.894819761,380460.5309751969,5626137.912301861

If I request both layers at the same time, I don't get a result:
Query-Layer: nw_tim_m_inb, nw_tim_h_inu
https://www.wms.nrw.de/geobasis/wms_nw_tim?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetFeatureInfo&FORMAT=image/png&TRANSPARENT=true&QUERY_LAYERS=nw_tim_m_inb,nw_tim_h_inu&LAYERS=nw_tim_m_inb,nw_tim_h_inu&INFO_FORMAT=text/html&RADIUS=10&I=50&J=50&CRS=EPSG:25832&STYLES=&WIDTH=101&HEIGHT=101&BBOX=379495.5134930965,5625172.894819761,380460.5309751969,5626137.912301861
