Nginx上的Varnish/Symfony3缓存-在缓存上为0

Question

我已经通过Docker在我的Symfony版本上设置了varnish，但是无法让缓存正常工作。不管我怎么尝试，年龄似乎都保持在0。

读到它可能与设置cookie或可能的expires头有关，但我无论如何也不能弄清楚发生了什么。

响应头部为：

Age:0
Cache-Control:max-age=64000, public, s-maxage=64000
Connection:keep-alive
Content-Type:text/html; charset=UTF-8

X-Powered-By:PHP/7.0.11

请求头部包括：

Accept-Encoding:gzip, deflate, sdch
Accept-Language:en-US,en;q=0.8

当前VCL文件：

vcl 4.0;

backend default {
    .host = "192.168.99.100";
    .port = "8080";
}

sub vcl_recv {
    unset req.http.Forwarded;

    if (req.http.X-Forwarded-Proto == "https" ) {
        set req.http.X-Forwarded-Port = "443";
    } else {
        set req.http.X-Forwarded-Port = "80";
    }

    // Remove all cookies except the session ID.
    if (req.http.Cookie) {
        set req.http.Cookie = ";" + req.http.Cookie;
        set req.http.Cookie = regsuball(req.http.Cookie, "; +", ";");
        set req.http.Cookie = regsuball(req.http.Cookie, ";(PHPSESSID)=", "; \1=");
        set req.http.Cookie = regsuball(req.http.Cookie, ";[^ ][^;]*", "");
        set req.http.Cookie = regsuball(req.http.Cookie, "^[; ]+|[; ]+$", "");

        if (req.http.Cookie == "") {
            // If there are no more cookies, remove the header to get page cached.
            unset req.http.Cookie;
        }
    }
}

更改为以下值不会产生任何影响：

sub vcl_recv {
    unset req.http.Forwarded;
    unset req.http.Cookie;
}

我猜它会是简单的东西，但不能让它工作。感谢您的任何帮助

Varnish不缓存设置Cookie的页面，并且在您提供的响应头中有一个Set-Cookie。

要解决此问题，您可以遵循以下两种方法：

• 继续使用Set-Cookie;
• Remove Set-Cookie从要缓存的页面中避免缓存那些页面；
• 或将所有操作与要缓存并通过AJAX调用的页面分开。<代码>H212<代码>F213
