    Hi,

    Could someone explain to me what does this mean:

    Did this request trigger a purge ?

    Thanks

    Hi Qtwrk,

    Wowww ! It’s worrying … This page (or this template ?) does not exist on my server.
    How can a request to a non-existent page trigger a purge ?

    173.249.52.122	-	-	[08/Feb/2024:20:24:48	+0100]	GET /simple.php HTTP/1.1	404	425848	www.google.com	Mozlila/5.0 (Linux; Android 7.0; SM-G892A Bulid/NRD90M; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/60.0.3112.107 Moblie Safari/537.36

    I can’t hide the fact that it worries me to see that the cache can be destroyed by this type of request !
    Do you have any ideas to explain this ?

    Thanks a lot in advance !
    Best regards

    hm , indeed it is weird

    does this repeatedly happen ? try use the debug include URI to grab full log on that request

    also you can try manually open this request , see if it triggers as well.

    Well….

    I’m afraid I’ve got a serious issue…

    If you want, I’ve got others, with /wp-l0gin.php, /priv8.php, and so on.

    So the same for numerous request which trigger a 404 error, and at the same time, a cache purge !!!
    I suspected that my host had placed limitations on the operation of the crawler, but, if a 404 error trigger a purge: I’m not going to make it.

    Have you ever seen anything like this ?

    Many thanks.

    (@qtwrk)

    no , never saw something like this before , but please try follow my previous method to grab a full log on any of these requests, see if it gives more details in the log.

    Thread Starter joy0114

    (@joy0114)

    You mean I add:
    /simple.php
    /wp-l0gin.php
    /priv8.php
    …

    in “debug include URI”

    And then I wait before displaying debug.purge.log ?
    It will give me more informations in the future, if others requests with same terms occur ?
    But for newer requests ?

    Last is concerning:
    02/09/24 12:28:56.890 [185.196.220.26:45771 1 PLU] /wp-content/plugins/booking/readme.txt
    Another 404, and another purge.

    Sorry for these questions, but I feel quite worried …
    Thanks so much

    (@qtwrk)

    yes, add them to debug include URI , then you can just access the URI yourself by browser, see if it generates any log and purges cache.

    Ok, thanks for your answer.

    I’m going to do it this night.
    Because my hoster seems to have introduced new rules, very painful, for the crawler: execution 3min, interval 1h … At this rate, you’d better get organized when there’s a cache purge …
    I’ll be back with the results.

    Have a good day and thanks again for your advices.

    Hi,

    Just before I was about to do this test, I caught a new 404 error which had triggered a purge:

    I’m sorry, colored icons are wrong encoded.
    After this, lots of informations about optimization, css, js and so on.

    I tried to reiterate this issue in calling a 404 error page already involved:
    //MY-WEB-SITE/simple.php or //MY-WEB-SITE/radio.php : it did not repeat the problem.

    But, in trying, by mymelf, /.env, I made a mistake and I typed //MY-WEB-SITE/;env

    And /;env caused this issue: purge of cache.

    If you have any idea, It would be… great !
    Thanks a lot
