One way to do it is to pass new parameters(with tha exact name of you're mapfile variable) in the GetFeatureInfo URL so it would look something like this:
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 *&**SEMCDC=<value>&**RSS=**<value>&**ORDRE**<value>* MapServer will then replace the value before returning the result. hope's this help....
