thanks for your reply.
best solutions is to put a checkbox after Preload cache in settings : like that : Repeat this process(preload) every : 1 hour, or 2 hours or 3 hours (list)
– now is 0 hour (start) : preload create first cache files.
– After 1 hours (if i set 1 hour) : preload recreate or rebuild new caches files with the same order and replace evey file created on 0 hours (start) : no need to cache timeout to clear all cache.
or if i can make “preload cache process” repeat for every hour
with overwritten files (replace exist cached files).
