Steve, I've opened up an OpenLayers bug [1]. In the meantime you can try<br>
and use vendorParams on the GetFeatureInfo control, but you need to update<br>
the property whenever your values change.<br>
<br>
Further discussion can best be done on the OL mailing list.<br>
<br>
[1] http://trac.openlayers.org/ticket/2358<br>
<br>
Best regards,<br>
Bart<br>
