Opencart 3.0.3.8 上的 .html URL 绕过 Varnish 缓存：如何修复缓存配置？

问题描述 投票：0回答：1

我在运行 AlmaLinux 8 并安装了 Plesk 的服务器上有一个 Opencart 3.0.3.8 站点。服务器使用 PHP-FPM 和 Nginx。

我的网站大约有 7,000 个产品，使用完整的 SEO 包模块进行 SEO。单一产品页面和信息页面都有一个 .html 扩展名（这是一个非常古老的设置的遗留物，这个电子商务网站已有大约 15 年的历史）。 Varnish 对于格式为 https://www.example.com/single-product-page 的页面没有问题，但是当我在 https://www.example.com/single-product-page 上查看页面时.html，我看到 x-cache-status 绕过。我已经尝试了一切，但无法解决这个问题。有专家可以告诉我哪里可能出错吗？

标头输出如下：

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

在 Plesk 面板中，为 http 定义了以下附加指令：

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

<IfModule mod_rewrite.c>
    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]
</IfModule>
#PLESK-VARNISH-END

附加 nginx 指令部分定义如下：

#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

这是default.vcl文件的内容：

# 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

日志可能会公开有关页面未缓存原因的更多信息。

假设我们正在调试假设的 

/single-product-page.html
产品页面，日志记录命令如下：

sudo varnishlog -g request -q "ReqUrl eq '/single-product-page.html'"

请将此 

varnishlog
命令的完整输出粘贴到您的原始问题中。输出可以包含多个相关交易（请求交易和后端请求交易）。

我将帮助您分析输出并弄清楚发生了什么。请确保在 

varnishlog
运行时触发该页面。另请调整过滤模式，以确保 
/single-product-page.html
替换为实际产品页面。
