    Hello,

    A LiteSpeed plugin update on one website purges cache for all websites on the server.

    Is it a known behavior? Can it be prevented?

    Thanks.

    this usually happens when all sites are configured to use same cache directory , where it supposedly , should have isolated and individual cache storage path

    please explain a bit what is your server env ?

    Thanks, @qtwrk.

    I’m using Shock Hosting‘s Shared Hosting.

    I’m not an expert in server environments.

    What information should I look for?

    emm , yes, I just noticed from source code, it does * where I think it should be per-site-tag , I am not sure why is that, checking with our devs

    actually I further looked into it and test on my server, it does not purge it server-wide 

    2024-08-29 14:59:24.638258 [DEBUG] [24193] [T0] [79.117.xxx.xxx:63428-H3:098570D6249BAD58-632#APVH_sample_domain.com:lsapi] Response Header: 'X-LiteSpeed-Purge: public,4c4_'

    it purges by per site tag

    may I know what is your server environment ?

    Thanks, @qtwrk.

    It is a shared, Linux, LiteSpeed server.

    What more details do you need?

    Thanks.

    go to toolbox -> debug setting , enable debug log , set debug level to advance , add wp-admin/admin-ajax.php to debug include URI , then do a plugin upgrade

    then check the log , see what it shows in the last line

    you should see somethign like this https://pastebin.ubuntu.com/p/mQmr2ncphn/

    the last few lines 10 => 'X-LiteSpeed-Purge: public,4c4_', , this one is the purge tag, see what it gives on your site

    I have explained what I have checked and tested , if you see different behavior , please share me the log as I requested

    @qtwrk

    I did as you requested.

    This is what I got:

    10 => 'X-LiteSpeed-Purge: public,*',

    This is from the Purge Log:

    09/05/24 11:06:52.884 [5.61.122.206:31012 1 462] X-LiteSpeed-Purge: public,* => LiteSpeed\LSC->send_headers()@624 => WP_Hook->apply_filters(,ARRAY)@324 => WP_Hook->do_action(ARRAY)@348 =>

    A wildcard seems to be used.

    Let me know if anything more is needed.

    Thanks.

    this doesn’t look like normal update , I was expecting things like update.php or wp-cron.php , were you using some kind of PWA ?

    (@asafm7)

    Thanks, @qtwrk.

    Yes, on this website I do use PWA. But on another website on this server, I don’t use PWA, and a plugin update on that website also triggers a cross-server purge.

    (@qtwrk)

    may I know which PWA that is? I will set up a test site and check around a bit , and meanwhile , please also share me the log on other site where doesn’t use PWA
