更新 WebUI 后面板内容未更新

[Larch-C]

前提：

之前使用时注意到，面板更新内容后，如果通过域名访问面板，那么面板显示的是旧的内容，但是从 IP+端口 访问就是新的内容。

后面排查是 Nginx 配置上的问题。
例如一般可能的反向代理配置是：

    location / {
        proxy_pass http://127.0.0.1:6185;
        proxy_set_header Host 127.0.0.1:$server_port;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header REMOTE-HOST $remote_addr;
        add_header X-Cache $upstream_cache_status;
        proxy_set_header X-Host $host:$server_port;
        proxy_set_header X-Scheme $scheme;
        proxy_connect_timeout 30s;
        proxy_read_timeout 86400s;
        proxy_send_timeout 30s;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }

可以由此解决问题：

    location = /index.html {
        proxy_pass http://127.0.0.1:6185;
        proxy_set_header Host $host;
        add_header Cache-Control "no-store, no-cache, must-revalidate" always;
        add_header Surrogate-Control "no-store" always;
        add_header Pragma "no-cache" always;
        add_header Expires "0" always;
        proxy_no_cache 1;
        proxy_cache_bypass 1;
    }
    
    location /assets/ {
        proxy_pass http://127.0.0.1:6185;
        proxy_set_header Host $host;
        expires 1y;
        add_header Cache-Control "public, max-age=31536000, immutable" always;
    }
    
    location / {
        proxy_pass http://127.0.0.1:6185;
        proxy_set_header Host $host;
        add_header Cache-Control "no-store, no-cache, must-revalidate" always;
        add_header Surrogate-Control "no-store" always;
        add_header Pragma "no-cache" always;
        add_header Expires "0" always;
        proxy_no_cache 1;
        proxy_cache_bypass 1;
    }

更新配置后，等待几分钟刷新页面（可以强制刷新： Ctrl + F5 ）就好了
