I saw your post on the openlayers list, and it seems from your
description of the problem that the SEMCDC, RCC and ORDER params are
included by OpenLayers in a GetMap request but it fails to include them
in the corresponding GetFeatureInfo request. If that's the case then
that's an issue with OpenLayers, or with the way you configure your
queryable layer in OL. I'm not fluent enough in OL personally to tell
where the solution lies, but if the params are missing in the URL then
the problem is definitely on the client side and not on the server.

Hi,
I already posted this problem on openlayers list, but it might be a
mapserver issue.
OpenLayers.Control.WMSGetFeatureInfo doesn't use the FILTER key in my
mapfile. This filter is define with variables like this:
FILTER "semcdc in (%SEMCDC%) and rss in (%RSS%) and ordre in (%ORDRE%)" .
The getMap request is succesfull but not the GetFeatureInfo request
Here is the request GetFeatureInfo
/cgi-bin/mapserv.exe?map=MYMAP
service=WMS&version=1.1.0&request=GetFeatureInfo&layers=ecoles&query_layers=ecoles&styles=&bbox=-8820221.560815%2C5721770.182129%2C-7587445.168853%2C6361395.234705&srs=EPSG%3A900913&feature_count=3000&x=272&y=457&height=523&width=1008&info_format=text%2Fhtml
Here is the response

</ServiceException>
</ServiceExceptionReport>
In OL, I have a WMS layer define like this:
new OpenLayers.Layer.WMS('ecoles',
'.../cgi-bin/mapserv.exe?map=MYMAP',{layers: 'ecoles', transparent:
"true", format:"image/gif", SEMCDC:thisCDC, RSS: thisRSS, ORDRE:
thisOrdre},{isBaseLayer: false, visibility:
false,singleTile:true,transitionEffect: 'resize'});
How should I query the layer?
Thanks
Steve
