Question

我们公司在内部使用一个应用程序，为所有经过身份验证的用户提供或多或少的静态内容。构建应用程序使其所有资源（js，css，图像，html页面）都经过身份验证。可悲的是，我似乎无法让Varnish为缓存经过身份验证的资源而工作。如果我使资源未经身份验证并使用以下VCL配置，则可以正常工作：

backend default {
  .host = "****";
  .port = "****";
}

sub vcl_recv {
    if (req.url ~ "^/js" || req.url ~ "^/css" || req.url ~ "^/images") {
            unset req.http.cookie;
    }    
}
sub vcl_fetch {
    if (req.url ~ "^/js" || req.url ~ "^/css" || req.url ~ "^/images") {
            unset beresp.http.set-cookie;
    }
}

但是，我正在寻找缓存，尽管资源经过身份验证，我理解这不是Varnish的默认行为。尝试

if (req.http.Authorization) {
        return(lookup);
}

vcl_recv中的

没有帮助。取消设置授权标头也无济于事（应用程序的身份验证搞砸了）。

我得到以下清漆日志（b-后端调用仍然发生）：

14 TxURL        b /_search
14 TxHeader     b Content-Type: application/x-www-form-urlencoded
15 RxURL        c /_search
15 RxHeader     c Content-Type: application/x-www-form-urlencoded
14 TxURL        b /admin
14 TxHeader     b Content-Type: application/x-www-form-urlencoded
17 RxURL        c /admin

17 RxURL        c /js/all.js?_=1385100392830

添加HTTP请求和响应标头：

请求标题：

有人可以提供一个可以提供帮助的VCL配置代码段吗？
