Drupal 按流5和清漆

我们当前运行的网站有：
按Flow 5.23.50
清漆2.1.4

我怀疑我遇到的一些问题是基于各种各样的文档，有些是最新的，有些不是

目前我收到这些响应标题：

清漆配置：
我们正在使用全局重定向模块，我在其中包含了我在网上找到的相应检查

我还在性能页面上将Drupal设置为“积极缓存”

是否有我遗漏的一些小东西，或者有人可以在其他事情上为我指出一个方向来尝试？

许多模块会启动会话或添加cookie，从而导致页面无法缓存。这里有许多可能性和解决方案：

关于调试哪个模块正在启动会话的一些提示

我也会看一看摇篮曲的文章：

使用多个Web服务器配置Varnish以实现高可用性

他们为drupal提供了一个完整的varnish配置，以及一个正确的varnish状态检查php脚本

$conf['reverse_proxy'] = TRUE;
$conf['reverse_proxy_addresses'] = array('127.0.0.1');
