It’s useful for me to create the symbolic links when I have sea coverage for example but a white tile can indicate a temporary failure with one WMS source which can’t find the source data but renders a white tile. I can use find and delete to remove the links but it’s inidscriminate.

no this is not possible.

But maybe you can ask the vendor of the WMS to return an exception and not a white image in case of an error? :-)

Oliver
