I need to take a filesystem backup of a website with Experience Manager enabled and I want to exclude all of the session preview pages and binaries:
index_d6550f29-5662-451d-bc90-a7dd9e83e6e9.html
It seems that a number of these have been left over either due to sessions that have remained open or failures during prior cleanup operations.
Is there a way of forcing a purge of existing/leftover session preview content delivery files?
