如何使用 WPtouch Pro 让 Varnish Place 变得漂亮

Question

我有一个使用 WPTouch Pro for Mobile 的 Wordpress 网站。我有一个带有清漆缓存的 nginx 服务器。问题是我无法让 Varnish WPTouch Pro 和 Wordpress 一起工作。网上有很多解决方案，但都没有奏效。附加的 default.vcl 是我能找到的最接近的。 Varnish 似乎正在缓存桌面和移动站点，并且都可以正常显示。但是现在 Wordpress 不能正常工作。我无法保存帖子，无法显示预览页面和登录困难。Varnish 似乎正在缓存管理页面。我知道有一个简单的解决方案。请帮我找到它。这是vcl

Answer 1

您需要传递包含 wordpress 登录 cookie 的内容。

在你的子 vcl_recv 中

# OPTIONAL: DO NOT CACHE LOGGED IN USERS (THIS OCCURS IN FETCH TOO, EITHER
  # COMMENT OR UNCOMMENT BOTH
  # ##########################################################
  if ( req.http.cookie ~ "wordpress_logged_in" ) {
    return( pass );
  }

WordPress 使用 hash_always_miss 的完整工作 vcl 是 here，您可能会发现它很有用
