I’ve gone back through this and read it again to try to familiarize myself with
the situation.
Is there a reason why GeoServer currently does it in the order it does it? For
instance, if I were to make the alternative — would it open up additional
issues that were prevented it from doing it how GeoServer currently does it?
Also, if you would be able to, can you point to where it’s located in the code?
Thanks,
Tyler Youschak
