“x-litespeed-cache: miss” after crawling hit problem

    Hi, I have a doubt.

    In my sitemap list I find many pages in “Cache Hit” (green dot), for all 4 crowlers.

    Requesting one of those pages via browser I would expect to find “x-litespeed-cache: hit” in the response header, instead I find a miss. Only after the refresh do I get a “hit” (and the response time is significantly shorter).

    Is this behavior normal? Shouldn’t crowlers be used to cache pages in advance and then take them out of the cache for the answer?

    Hi,

    is the information on report accurate ? because the domain gives DNS_PROBE_FINISHED_NXDOMAIN error

    if you manually start the crawler , after it finishes , then immediately open the page , do you see hit or miss ?

    this way will at least narrow down the issue to crawler itself , or something else

    Best regards,

    First of all, thank you for looking at the report. The report is sent by the plug-in itself, I think it is sufficiently accurate. I have already done the test you suggest and even if the crawler indicates the page with a HIT, I connect (immediately) and find MISS. As a browser it works, because when I refresh the page I find a HIT.

    Regarding the error message you have identified, I can tell you that the domain the crawlers browse is not actually set to DNS but set at system level as an IP-domain association in the host file of the server (CentoOS 8) and of the operating system my client is running on (Windows 10).

    Can you please explain to me what it refers to? How does the crawler cache a page if it cannot reach it due to the problem in the DNS?

    Thanks again, Paolo.

    Hi,

    please try go to General -> server IP -> set your server IP there , then crawl it again , and make sure the status code shows in green or blue

    Hi!

    A few days ago I set the IP as you suggested, in fact it was not set. However, despite having many URLs in green or blue, from the browser I always find MISS (and relative slowness …).

    I have linked you a PDF with some screenshoots.

    Thanks again for your help, you will surely help me to solve this problem !!!
