    Hi there

    I was accepted to try a adblock-blocking technology. They support APC and Xcache as a standard. When testing it logged in, it works flawlessly but once logged out, it seems to not work.

    A certain php backend loader has to be running when someone visits. How would I go about excluding that ? Or maybe exclude everything coming from a single plugin, folder or cookie ?

    Thank you

    You using APC or Xcache both are dated and less performant than Centmin Mod default installed Zend Opcache for PHP-FPM.

    To exclude per vhost, you can try similar approach to @nVidian for Zend Opcache PHP-FPM - Enable/Disable Zend Opcache per vhosts

    For APC Cache, see PHP: Runtime Configuration - Manual and apc.filters setting PHP: Runtime Configuration - Manual

    Then try something like caching - how to exclude .php file from APC cache? - Stack Overflow Edit /etc/centminmod/php.d/apc.ini APC Cache ini file which you can find using php --ini command for all .ini PHP related file paths

    Code:
    php --ini
Configuration File (php.ini) Path: /usr/local/lib
Loaded Configuration File:         /usr/local/lib/php.ini
Scan for additional .ini files in: /etc/centminmod/php.d
Additional .ini files parsed:      /etc/centminmod/php.d/apc.ini,
/etc/centminmod/php.d/igbinary.ini,
/etc/centminmod/php.d/imagick.ini,
/etc/centminmod/php.d/memcache.ini,
/etc/centminmod/php.d/memcached.ini
    Edit apc.ini and add

    Code:
    apc.filters = "-/home/nginx/domains/newdomain.com/public/.*"
    restart PHP-FPM service

    Code:
    service php-fpm restart
    or

    Code:
    fpmrestart

    Oh, you mis understood, I'm not using apc or xcache :) (I am using centminmod with nothing but praise and love for it) I was saying that the specific plugin had support built in for those but not for zend opcache. Thank you, I'll look into the options above!

    Just another question @eva2000
    As read in this thread: Wordpress - Revisiting Wordpress Cache Enabler + Autoptimize Plugins For Page Load Speed Optimization

    <!--
    Centmin Mod centmin.sh menu option 22 auto installes Wordpress with Cache Enabler's advanced cache configuration when selecting option 1 above so header responses for php would have X-Cache-Handler: wp meaning caching bypasses PHP (php-fpm) for best performance as opposed to seeing X-Cache-Handler: php which means cache goes through PHP which isn't optimal.--!>

    My website was setup with cache enabler (option 1).
    Pages are showing x-cache handler WP
    how would I go about turning that into x-cache handler php ?

    that is best performance what you're asking is to lower performance/slow down your site by using x-cache handler php
