Lack-Cache für .html-URLs in Opencart 3.0.3.8 umgangen: Wie kann die Caching-Konfiguration korrigiert werden?

Guest · Post by **Guest** » 31 Dec 2024, 14:54

Ich habe eine Opencart 3.0.3.8-Site auf einem Server, auf dem AlmaLinux 8 mit installiertem Plesk läuft. Der Server verwendet PHP-FPM und Nginx.
Meine Website, die etwa 7.000 Produkte umfasst, verwendet das Modul „Complete SEO Package“ für SEO. Einzelne Produktseiten und Informationsseiten haben die Erweiterung .html (ein Überbleibsel einer sehr alten Einrichtung – diese E-Commerce-Site ist etwa 15 Jahre alt). Varnish funktioniert ohne Probleme für Seiten im Format https://www.example.com/single-product-page, aber wenn ich die Seite unter https://www.example.com/single-product-page.html ansehe, Ich sehe die Umgehung des x-cache-status. Ich habe alles versucht, kann dieses Problem aber nicht lösen. Können mir Experten sagen, wo ich möglicherweise falsch liege?
Die Header-Ausgabe lautet wie folgt:

Code: Select all

content-encoding: gzip
content-type: text/html; charset=utf-8
date: Tue, 31 Dec 2024 13:26:58 GMT
permissions-policy: keyboard-map=(), attribution-reporting=(), run-ad-auction=(), private-state-token-redemption=(), private-state-token-issuance=(), join-ad-interest-group=(), idle-detection=(), compute-pressure=(), browsing-topics=()
server: nginx
vary: Accept-Encoding
x-cache-status: BYPASS
x-dns-prefetch-control: off
x-powered-by: PHP/7.3.33
x-powered-by: PleskLin

Im Plesk-Panel ist die folgende zusätzliche Direktive für http definiert:

Code: Select all

#PLESK-VARNISH-BEGIN
SetEnvIf X-Forwarded-Proto https HTTPS=on
Header set Vary "Accept-Encoding" env=!NO_VARY


RewriteEngine on
# We remove HTTPS redirection because we are behind Varnish
# RewriteCond %{HTTPS} !=on
# RewriteCond %{HTTP:X-Forwarded-Proto} !https [NC]
# RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

#PLESK-VARNISH-END

Der Abschnitt „Zusätzliche Nginx-Anweisungen“ ist wie folgt definiert:

Code: Select all

#PLESK-VARNISH-BEGIN
location ~ ^/.* {
proxy_pass http://0.0.0.0:6081;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Port $server_port;

# Edit cookie and cache headers
proxy_hide_header Set-Cookie;
proxy_ignore_headers Set-Cookie;
proxy_set_header Cookie "";

# Timeout settings
proxy_connect_timeout 300;
proxy_send_timeout 300;
proxy_read_timeout 300;
}
#PLESK-VARNISH-END

Und hier ist der Inhalt der Datei default.vcl:

# UPDATED on December 15th, 2021
#
# Configuration Notes:
# 1. Default dynamic content caching respects your backend's cache-control HTTP header.
#    If however you need to enforce a different cache-control TTL,
#    do a search for "180" and replace with the new value in seconds.
#    Stale cache is served for up to 24 hours.
# 2. Make sure you update the "backend default { ... }" section with the correct IP and port
