Page cache life-time: 4 hours Do not show caches older then 24 hours
What exactly is the meaning of these? Will it auto-generate cache every 4 hours? Or it will generate new cache when page is requested and cache file is over 4 hours?
And what is the 24 hours here? If the cache is older than 24 hours, whats then? If "Do not show caches", what will it show?
Another question is about
Distinct gadgets - mobiles, tablets and PC (enable if your shop gives different pages to different gadgets)
Is it about responsive design or completely different url for mobiles? As far as I know, default Opencart does not make separate pages for mobiles. Can you elaborate on this, please?
Thanks in advance,
