wordpress - Varnish 4.0.1、Apache、Centos 7、Plesk 12、带有 w3 总缓存的 Wordpress - Varnish 不缓存 html

Question

前几天我在我的网站上设置了清漆，但我认为它不能正常工作，因为年龄显示为 0：

静态内容完美运行：

这就是 isvarnishworking.com 对此的看法：

Varnish appears to be responding at that url, but the Cache-Control header's "max-age" value is less than 1, which means that Varnish will never serve content from cache at this url.

这是我的 .htaccess 的副本（使用 w3 总缓存制作）：

我可以看到静态文件和 html 之间唯一不同的是 html 页面正在发送 cookie，所以我尝试修改我的 default.vcl 以取消设置 cookie，如下所示：

sub vcl_recv {
if ( !( req.url ~ ^/admin/) ) {
unset req.http.Cookie;
}
}

我现在对此完全感到困惑，所以任何帮助将不胜感激

Answer 1

根据您问题的第一部分：

Set-Cookie: iSLuxE=1; expires=Wed, 24-Feb-2016 12:57:14 GMT; Max-Age=10800

来源正在发回 cookie，而 Varnish 不会缓存这些 cookie。

所以你会想做一些类似的事情，假设 cookie 实际上并不相关：

sub vcl_backend_response {
    unset beresp.http.Set-Cookie;
}

但是，如果请求和响应 cookie 都是不必要的，那么您似乎可以将它们从应用程序中删除。如果 cookie 是静态且可缓存的（并且可能用于不同的子域），您可以暂时“移动”它们并在响应时恢复它们：

sub vcl_backend_response {
    set beresp.http.X-Set-Cookie = beresp.http.Set-Cookie;
    unset beresp.http.Set-Cookie;
}

sub vcl_deliver {
    set resp.http.Set-Cookie = resp.http.X-Set-Cookie;
    unset resp.http.X-Set-Cookie;
}

这应该允许 Varnish 在不丢失 cookie 的情况下进行正常的缓存处理。
