Wordpress Cache-Enabler Plugin WP Cacher Enabler Plugin by KeyCDN folks

Okay I knew of WP Cache Enabler Plugin by KeyCDN folks, but @Matt Williams says it's better than WP Super Cache. So started a new thread to discuss WP Cacher Enabler Plugin.

First things from WordPress Cache Enabler Plugin - KeyCDN Support

??

---

 

Yes testing it out on a new centmin.sh option 22 generated Wordpress + WP Super Cache set and doing manual conversions for now.



So to convert from WP Super Cache based to WP Cache Enabler based I created a new include file /usr/local/nginx/conf/wpcacheenabler_domain1.com.conf

contents of /usr/local/nginx/conf/wpcacheenabler_domain1.com.conf

Code (Text):

    # Block nginx-help log from public viewing
    location ~* /wp-content/uploads/nginx-helper/ { deny all; }

    set $cache_uri $request_uri;

    # exclude mobile devices from redis caching
    if ($cmwpcache_device = mobile) { set $cache_uri 'nullcache'; }

    # bypass cache if POST requests or URLs with a query string
    if ($request_method = POST) {
        set $cache_uri 'nullcache';
    }
    if ($query_string != "") {
        set $cache_uri 'nullcache';
    }

    # bypass cache if URLs containing the following strings
    if ($request_uri ~* "(\?add-to-cart=|/cart/|/my-account/|/checkout/|/shop/checkout/|/store/checkout/|/customer-dashboard/|/addons/|/wp-admin/|/xmlrpc.php|/wp-(app|cron|login|register|mail).php|wp-.*.php|/feed/|index.php|wp-comments-popup.php|wp-links-opml.php|wp-locations.php|sitemap(_index)?.xml|[a-z0-9_-]+-sitemap([0-9]+)?.xml)") {
        set $cache_uri 'nullcache';
    }

    # bypass cache if the cookies containing the following strings
    if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_logged_in|edd_items_in_cart|woocommerce_items_in_cart|woocommerce_cart_hash|woocommerce_recently_viewed|wc_session_cookie_HASH|wp_woocommerce_session_|wptouch_switch_toogle") {
        set $cache_uri 'nullcache';
    }

    # bypass cache for woocommerce
    if ($arg_add-to-cart != "") { 
        set $cache_uri 'nullcache';
    }

    ## bypass cache for empty woocommerce carts
    #if ($cookie_woocommerce_items_in_cart != "0") { 
    #  set $cache_uri 'nullcache';
    #}

    # custom sub directory e.g. /blog
    set $custom_subdir '';

    # default html file
    set $cache_enabler_uri '${custom_subdir}/wp-content/cache/cache-enabler/${http_host}${cache_uri}index.html';

    # webp html file
    if ($http_accept ~* "image/webp") {
        set $cache_enabler_uri '${custom_subdir}/wp-content/cache/cache-enabler/${http_host}${cache_uri}index-webp.html';
    }

then deactivate wp super cache and wp super cache purge cache addons from wp admin

then edit nginx vhosts for test domain1.com site at /usr/local/nginx/conf/conf.d/domain1.com.conf (and do same for ssl version at /usr/local/nginx/conf/conf.d/domain1.com.ssl.conf)

This is tested on Centmin Mod 123.09beta01 which has commented out php redis nginx level cache support too which is 45% faster than WP Super Cache see benchmarks of WP Super Cache vs Nginx level Redis Cache.

paying attention to web root location change for try_files too

Code (Text):

  # for wp cache enabler plugin
  try_files $cache_enabler_uri $uri $uri/ $custom_subdir/index.php?$args;

and adding new include file

Seems WP Cache Enabler is simpler to configure so far

Setup a cronjob to expiry the cache as outlined at Wordpress - WP Cacher Enabler Plugin by KeyCDN folks | Page 3 | Centmin Mod Community

Modify the path to your wp-content/cache/cache-enabler directory and edit ${DELAY} with a 3 digit number i.e. 123 which means delay run by 123 seconds. This ensures no 2 cronjobs run into each other at the same time. And edit ${vhostname} with your domain.com name.

Code (Text):

16 23 * * * echo "$vhostname cacheenabler cron"; sleep ${DELAY}s ; rm -rf /home/nginx/domains/${vhostname}/public/wp-content/cache/cache-enabler/* > /dev/null 2>&1

 

Heads up folks, I've added preliminary support for WP Cache Enabler plugin setup via centmin.sh menu option 22 for Centmin Mod 123.09 beta01 builds for testing. Actual commit add Wordpress Cache Enabler Plugin support to centmin.sh option 22 · centminmod/centminmod@a5fdbce · GitHub

If you answer yes when prompted to install WP Cache Enabler instead of WP Super Cache, you auto install WP Cache Enabler and Optimus WP Plugins + auto activate them. WP Super Cache plugin gets installed but not activated, convenient if you need to switch between them.

Also all the additional addons which @Matt Williams said he didn't need are now optional and not installed by default.

Check to see if WP Cache Enabler is working as it's auto installed and activated out of the box. Looks like it's working and less finicky than WP Super Cache

Code (Text):

curl -s http://domain2.com | grep 'Cache Enabler'
<!-- Cache Enabler by KeyCDN @ 01.12.2015 20:47:54 (html) -->

 

probably stay in 123.09beta01 for more testing and more feedback

 

ah but don't you want to test all the goodies outlined in Centmin Mod 123.09beta01 Change Log ?

 

yeah.. that's why i have stable and beta builds these additions to beta need testing first

 

KeyCDN developers of WP Cache Enabler plugin posted benchmarks at WordPress Cache Plugin: Benchmarking Cache Enabler

 

heh still needs testing as it's risky to introduce an untested setup into a stable release - the same logic that prevents you introducing 123.09beta for your clients in production sites as me introducing untested/beta code into 123.08stable

oh and faster and more 123.09beta testing and feedback, the faster it goes stable

 

i mean the centmin.sh 22 automated routine testing

 

Yeah official centminmod.com site is running 123.09beta01 too and so is the forum now Forum server switch to Centmin Mod 123.09beta01 branch | Centmin Mod Community

 

best to post the original nginx vhost conf files to double check, they should of be created

one is an include file at /usr/local/nginx/conf/wpcacheenabler_${vhostname}.conf

Code:

include /usr/local/nginx/conf/wpcacheenabler_${vhostname}.conf;
#include /usr/local/nginx/conf/wpsupercache_${vhostname}.conf;
# https://community.centminmod.com/posts/18828/
#include /usr/local/nginx/conf/rediscache_${vhostname}.conf;  

and other at centminmod/wpsetup.inc at 123.09beta01 · centminmod/centminmod · GitHub which gets auto uncommented if cache enabler is selected. But i noticed a bug in the variables were not escaped will fix that. Update: fixed at update inc/wpsetup.inc properly escape cache enable try_files · centminmod/centminmod@5bc118c · GitHub
