Frequently Asked Questions
Common questions about Zinn® Cache
Open Zinn Digital® → Cache → Status and press Check now. If nginx caches your pages, the screen says so and Zinn® Cache does not install its own page cache behind it. Then open the Server cache tab, choose nginx, and choose how to purge it: a purge request per page if your nginx has the ngx_cache_purge module (set "Send purges to" to http://127.0.0.1 when a CDN is in front); delete the cache files if WordPress can read the folder in your proxy_cache_path or fastcgi_cache_path line (copy the folder, the levels= value and your cache key); or write the addresses to a folder your host's purger reads. Save, then purge one address from the Status tab and check that its next visit says MISS. If nginx does not cache your pages at all, choose None and Zinn® Cache's own page cache does the job.
Varnish: choose Varnish, give its address and port, and allow PURGE (or BAN) from this server in your VCL. Apache: put mod_cache in a reverse-proxy virtual host in front of WordPress — inside the same server as WordPress's own rewrite rules, Apache stores every address as /index.php and can serve one page for all of them; the status screen warns when it sees that. Cloudflare: switch on Cloudflare purge and paste a zone ID and a token limited to Cache Purge.
Because emptying it sends every visitor and every crawler to WordPress in the same minute, and on a large site that can take the server down. Updates, plugin activations, theme and menu changes start a paced refresh: every page is refreshed, a batch a minute, newest first, until the whole site is done, and the refresh pauses while the server is busy. Empty all now on the settings screen empties everything at once when you want that.
On purpose. Combining files was a workaround for HTTP/1.1; on HTTP/2 and HTTP/3 it makes pages slower to start and breaks caching of shared files, which is why other cache plugins have been retiring it. Minifying saves a few percent once files are compressed (gzip or Brotli) and is the most common cause of a broken layout after installing a cache plugin. A separate mobile cache doubles every cached page and every server-cache key for themes that are responsive anyway; Zinn® Cache Pro's warm-up can warm a mobile pass for the few sites that do serve phones a different page.
Full-page caching requires a LiteSpeed web server (or the third-party LiteSpeed Cache plugin). On any other server nothing reads the cache headers, so pages are not cached — and the settings screen says so plainly rather than looking as if it works. Everything else (object cache, exclusions, and the signed purge endpoint) still works.
No. If the LiteSpeed Cache plugin is active, Zinn® Cache defers page caching to it and routes purges through its public actions.
The object cache is optional. If the phpredis extension is missing the toggle is disabled with a notice; if Redis becomes unreachable at runtime, the drop-in serves from a per-request in-memory cache so the site never breaks.
With WP-CLI: wp zinn-cache purge all empties every cached page, wp zinn-cache purge url https://example.com/pricing/ (or just /pricing/) empties those pages, and wp zinn-cache purge post 42 empties a post's page and the lists it appears on. Each prints how many stored pages it removed. On a LiteSpeed server the purge is sent to the server with the next request, which the command makes itself.
