    Hello!

    I have some doubt if the litespeed cache its ok or not, headers made me extra confusion then i decided to ask a help there.

    once you have cf-cache hit , it will cache the current headers as well , by that saying, even after this request the litespeed cache is hit , it will still display cache miss

    Pragma is kind of ancient header and is Deprecated , but it works as cache-control: no-cache , this is expected for the main request over a dynamic page

    if you are using CF cache with LSCWP, then certain options like Guest Mode , Webp replacement , mobile cache , JS minify/combine , CSS minify/combine , need to be disabled

    Hello! thank you for your reply.

    Honestly i made a re-check with Google inspect and looks like Litespeed cache has hit, but Cloudflare’s cache was bypassed per the Cache-Control header.

    Idk why the result are so different, in any case what is the ideal setup? i have to use CF or LTC ?
