In short, This would mean to add a new node type in the config.xml 
<filter> [1]. This node would contain expressions or BBox and would be 
attached to a <resource>. From now, all call to this resource would go 
through this filter on the server-side (proxy.php). If it's a WMS 
request, the proxy would apply a WMS Filter Encoding on the request. If 
it's a FeatureServer request, it would add the needed filter on the request.

Once this is done, you would need to assign the right resource to the 
right roles to get filtered information. Does that make sense?
