You're GetFeatureInfo request cites version=1.3, where it should pass
1.1.1. What happens if you send a request like:
http://localhost/cgi-bin/mapserv?map=/var/www/workshop/itasca.map&SRS=EP
SG:4326&BBOX=-99.30245,43.4354,-87.36445,49.404399999999995&TRANSPARENT=
TRUE&BGCOLOR=0xFFFFFF&EXCEPTIONS=application/vnd.ogc.se_xml&WIDTH=800&HE
IGHT=400&LAYERS=airports&STYLES=&REQUEST=GetFeatureInfo&VERSION=1.1.1&SE
RVICE=WMS&INFO_FORMAT=gml&X=363&Y=121&FEATURE_COUNT=100&QUERY_LAYERS=air
ports
It behaves exactly the same (the results with SRS and CRS are the same).

Hello,
When I issue a GetCapabilities on my installation of mapserver, using
the following URL:
http://localhost/cgi-bin/mapserv?map=/var/www/workshop/ita
sca.map&service=WMS&version=1.3&request=GetCapabilities
I get a capabilities document showing:
<WMT_MS_Capabilities version="1.1.1">
So, the service expects requests of version 1.1.1 of the WMS
spec, but
when I issue a GetFeatureInfo with this URL:
http://localhost/cgi-bin/mapserv?map=/var/www/workshop/itasca.
map&SRS=EPSG:4326&BBOX=-99.30245,43.4354,-87.36445,49.404399999999995&TR
ANSPARENT=TRUE&BGCOLOR=0xFFFFFF&EXCEPTIONS=application/vnd.ogc.se_xml&WI
DTH=800&HEIGHT=400&LAYERS=airports&STYLES=&REQUEST=GetFeatureInfo&VERSIO
N=1.3&SERVICE=WMS&INFO_FORMAT=gml&X=363&Y=121&FEATURE_COUNT=100&QUERY_LA
YERS=airports
I get the following error:
<ServiceExceptionReport version="1.1.1">
<ServiceException code="InvalidSRS">
msWMSLoadGetMapParams(): WMS server error. Invalid SRS given : SRS
must be valid for all requested layers.
</ServiceException>
</ServiceExceptionReport>
hmm. But then, if I change the SRS parameter name to CRS, I get a valid
(though empty) result:
<msGMLOutput
xmlns:gml="http://www.opengis.net/gml";
xmlns:xlink="http://www.w3.org/1999/xlink";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
</msGMLOutput>
The weird thing is that in the version 1.1.1 of the spec, there is no
CRS parameter for the GetFeatureInfo, but an SRS parameter. SRS was
changed to CRS at version 1.3.
It looks to me like a bug, am I wrong?
Best regards,
Arnaud
Last Minute Addendum: When I try with the equivalent (projected) native
logical bbox, in the native SRS (EPSG:26915, this is the Itasca demo!)
mapserver doesn't mind the name of the SRS param. Both SRS and CRS work.
Now, I'm totally lost o_O
Will mapserver refuse to work properly if asked for features with a 4326
box?
Thanks for any information!
