Cache busting

clear cache, busted

Busted! was the first to do it, but it is now abandoned. For more information, check out WordPress Cache Busting Techniques Done Right and Busted: A WordPress Plugin to Force Cache Busting.

reBusted! is an improved version of the original Busted!, although both are messy in terms of object-oriented programming bloat, and both use four hooks: wp_enqueue_scripts, admin_enqueue_scripts, stylesheet_uri, and locale_stylesheet_uri.

Cachebuster and Cache Buster are functionally identical previous plugins, with both being very clean and utilizing only two hooks: style_loader_src and script_loader_src.

Super Light Cache Buster plugin from the Mwalek/super-light-cache-buster repository ensures that CSS & JS assets have random version numbers to combat browser and page caching, and I like it due to its feature allowing manual cache clearing by changing the “version name”. Refer to the provided screenshot for guidance on how to use the features:

Prevent Browser Caching

nginx setting for browser caching of static assets

# Cache static content
# Note: webpagetest.org needs a week for A grade
#
location ~* \.(?:css|js|jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp4|ogg|ogv|webm|htc)$ {
    expires 1w;
    access_log off;
    add_header Cache-Control "public";
}

Very simple explanation of browser caching headers.

Ultimativno browser caching je da cache nikada ne expire, a da nako modifikacije menjamo ime asset-a odnsono radimo cache-busting (aka fingerprinting) dodavanjem nekog query stringa. Ovakav proces je objašnjen u članku Your Cache Headers Could Probably be More Aggressive

Cache Buddy by Mark Jaquith offers a unique approach to WordPress plugins. To delve deeper into its features, refer to the article Introducing Cache Buddy: a companion for your WordPress page caching solution by Mark on WordPress.

Purge Server-side cache

cache purge, cache clear

The Cache Purger this plugin attempts to purge all server-side caching methods i meni izgleda vrlo dobro.

Probaj ovaj plugin da napraviš:

A ovde je purge Hummingbird cache: https://plugins.svn.wordpress.org/wp-hummingbird-purger/trunk/wp-hummingbird-purge.php

Ako server ne kešira ništa što ima neki query string, alternativa je da menjam ime. Kao što to radi vite.js i ostali build toolovi. Ali to je baš problem. Mogu nekako na nivou plugina, da pravim folder u uploads a zatim u identičnim kao plugin da pravim istu strukturu. Sranje je što moram da iskopiram bukvalno sve assete u istoj strukturi ako se promeni samo jedan asset, što je nebuloza.

Borlabs ima opciju “Clear Third-Party Cache” pa proveri kako je to implementirano, ali definitivno na radi za Raidboxes
