Serving stale pages for WP

    First I tried to achieve this for OpenCart. No success according to response time.
    But even if I enable the setting in the WP plugin, it doesn’t make a difference either.
    Is there any confirmation that should be visible in the header? Something like:
    x-litespeed-cache: stale
    Maybe the problem is at the server level, not the plugin.

    I purge an article and there is no stale page served at first visit, header has a x-litespeed-cache: miss value.
    The stale setting is ON.
    Next visits have obvious lower TTFB, and value is changed to hit.
    Is there a specific method to confirm that stale pages are served?
    This is the domain I am working on now.

    Hi,

    the “stale” doesn’t work the way you expected

    in this case, with LiteSpeed, the stale works as follow :

    assuming you have a page that cache has or about to be expired , then let’s say , there is 10 people requested this same page at same time

    and then , the first user will trigger cache regeneration , and rest of 9 people will get the staled cache for this page , after this time , all newer visitor will get the cached generated by visitor 1

    in which , stale cache is only lived like 1 or 2 seconds and then be flushed/replaced by newly regenerated cache on a heavy concurrent connection situation.

    Best regards,
