php - 如何使用 WPtouch Pro 使 Varnish 位置美观

Question

我有一个使用WPTouch Pro移动版的Wordpress网站。我有一个带有 Varnish 缓存的Nginx服务器。问题是我无法让Varnish WPTouch Pro和Wordpress协同工作。 Web上有很多解决方案，但是没有任何效果。随附的default.vcl是我能够获得的最接近的。 Varnish似乎正在为两个台式机和移动网站都缓存，并且都正确显示。但是现在Wordpress无法正常工作。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。

在您的子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可以使用hash_always_miss的完整工作vcl是here，您可能会发现它很有用
