304 Not Modified don’t find

  • LiteSpeed LScache (the cache engine of LiteSpeed web server) supports “If modified since” header, but it depends on if you have ESI enabled in cache plugin and if cache-control for browser cache is not set manually in .htaccess. If ESI is enabled in cache plugin the support for “If modified since” is disabled by design. If cache-control for browser caching is set manually and if it has “no-cache” then “If modified since” can’t be used.

    @mukoka thank you, but how to ESI enabled in OLS cache plugin?
    i can’t find it

    If you don’t use WooCommerce don’t care about ESI. OLS doesn’t support ESI, so you only care about if cache-control for browser caching is set. There must be any cache-control:no-cache!!!
