• The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Issue NGINX Cache won't cache static files

Plesk version and microupdate number
Plesk Obsidian 18.0.65
Hi folks,

I have a problem with my NGINX proxy cache.

(Plesk Obsidian on AlmaLinux 9)

My settings are as follows in Plesk for the domain:

Proxy mode: on
Intelligent processing of static files: on
Serve static files directly through nginx: off

Cache size: 512MB
Time limit: 30 days
Key: $scheme$request_method$host$request_uri

My additional instructions:

set $no_cache 0;
proxy_cache_valid 200 30d;
proxy_cache_valid 404 10m;
proxy_cache_valid 206 30d;
add_header Cache-Control “public, max-age=2592000”;

The main domain is cached and the header also contains “HIT”.
Unfortunately, however, the static files (jpg, css, js, mp4, etc.) are not cached and “MISS” is constantly displayed.

What could be the reason for this?

Here is the nginx.conf generated by Plesk: NGINX Conf - PLesk - Pastebin.com

Not that I know of.
This is the .htaccess file from WP:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteRule ^en/wp-login.php /wp-login.php [QSA,L]
RewriteRule ^de/wp-login.php /wp-login.php [QSA,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

The strange thing is that although the status of the X-Cache is MISS, the static contents are loaded from the ‘Memory Cache’ (according to the inspector).
The X-Cache header is as generated by Plesk. I have not entered any directives of my own.
If the static files are loaded from the ‘memory cache’, does this mean that the cache is active after all? Then I wonder why it always says ‘MISS’?
 
Thanks. How about in the /wp-content folder?

As far as I am aware, this is in reference to the local browser cache rather than the server cache.
