Cached pages get purged within minutes

    Report: QFJVJEMS

    Litespeed cache has been set to cache everything for 1 week and purging has been disabled completely. However I still see pages miss on the first visit. For example on 17:09 I visited a page and after that it was cached according to the headers and timestamp in the pagesource. At 17:16 I had another miss and the timestamp updated.

    The crawler shows a lot of missed pages even after a manual run.

    How do I prevent litespeed purching the cache?

    Hi, alright I have enabled the debug log and noted the tags of 4 different pages. Now I guess I have to wait.

    In the meanwhile does cache get destroyed when the litespeed webserver restarts? (Htaccess rewrites trigger a restart of the webserver).

    Update:
    Ok so yesterday I noted

    <!-- Page generated by LiteSpeed Cache 4.4.3 on 2021-10-22 04:01:10 -->
<!-- X-LiteSpeed-Cache-Control: public,max-age=604800 -->
<!-- X-LiteSpeed-Tag: 2ab_HTTP.200,2ab_page,2ab_URL./haarwerken/,2ab_Po.3691,2ab_PGS,2ab_ -->

    I checked 10 hours later:

    view-source:https://x.nl/haarwerken/
<!-- Page generated by LiteSpeed Cache 4.4.3 on 2021-10-22 11:12:49 -->

    So the tag is missing (because non-admin ip generated the new page?)

    debug.purge.log only contains woocommerce related entries
    debug.log shows only 2 entires for this url

    first entr is from when i manually purged all cache and visited pages:

    There is no log entry for 11:12:49. Probably because as instructed per guide I selected the admin ip option.

    I will switch debug logging to ‘on’ instead of ‘admin’ and only log 2 pages. Let’s hope that gives the results needed.

    Hi,

    restart webserver should not make cache purged

    yes , the page tag in HTML comment only shows to admin IP

    meanwhile when you do log , did you do something during this period ? like eidt/publish/change setting ….etc

    No, not that I know of. I thought it was fixed for a bit but it is having the same problem now.

    I do not see this page in the debug.purge.log

    Also:
    remove cache at upgrade = off
    automatic removal rules = everything removed

    It must be one of the hooks listed at 

    switch_theme
wp_create_nav_menu
wp_update_nav_menu
wp_delete_nav_menu
create_term
edit_terms
delete_term
add_link
edit_link
delete_link

    Wait I now see that when checking the website as in-private that the pages are cached:

    <!-- Page generated by LiteSpeed Cache 4.4.3 on 2021-10-29 11:26:20 -->
<!-- X-LiteSpeed-Cache-Control: public,max-age=604800 -->
<!-- X-LiteSpeed-Tag: 2ab_HTTP.200,2ab_page,2ab_URL./vestigingen/breda/,2ab_Po.2912,2ab_PGS,2ab_ -->

    So it seems the primary issue has been fixed by unchecking all automatic removal rules. Is there a setting to cache logged-in users? I do not mind clearing the cache myself the website is pretty static.
