<br>
I'm just asking questions to fully understand the use case. Thank you <br>
for your feedback. You mentioned an interesting point.<br>
<br>
As you mentioned, the solution can be based on the server side if the <br>
map server accepts an SLD.<br>
<br>
This approach can not be used against WMS services working behind <br>
caches/tiling services providing only predefined styles.<br>
