Hi all,
I think I implemented the suggested solution correctly by
* creatin a new ecpp nocache
* adding the nocache before the mapping for the files which should not be
cached.
Is there a straightforward way to debug if the no-cache property and other
ones in general are actually set?
Thanks,
Raphael
