[mapserver-users] Why is LAYERS parameter required in GetFeatureInfo

[Bart van den Eijnden]

The WMS spec does say it is required:

7.3.3.4	map_request_copy
<map request copy> is not a name/value pair like the other parameters. Instead, most of the GetMap request parameters that generated the original map are repeated. Two are omitted because GetFeatureInfo provides its own values: VERSION and REQUEST. The remainder of the GetMap request shall be embedded contiguously in the GetFeatureInfo request.

Best regards,
Bart
