getfeatureinfo in a wms

[Bart van den Eijnden]

Mapserver does not cascade WMS GetFeatureInfo, it will not ask the 
remote server for feature info. This is because the response is poorly 
defined in the WMS spec.

So you would need to build the GetFeatureInfo URL to the remote server 
yourself in the client and do the request and present the results. If 
you are using Mapscript there is a function in the API which builds up 
the GetFeatureInfo URL for you.

Best regards,
Bart
