用Symfony 2.1.13编写的应用程序的部分用户打开非常缓慢。 我发现了一个问题。对于这些由于某种原因打开速度较慢的用户，浏览器尝试下载所有css / js文件，但无法执行此操作（403）：

对于那些工作迅速的用户，应获取应有的版本或最低版本：

xxx.xxx.xxx.xxx - user_2 [28/Feb/2019:12:42:32 +0100] "GET /css/prod/prod_css.css HTTP/1.1" 200 (...)

我想指出的是，我已经排除了浏览器，系统等，因为如果在同一台计算机和浏览器上，它以（以...身份运行）登录两个用户，则它们将是相同的（慢会很慢，正常工作会正常工作
有人知道为什么会这样吗？

它修复了两天，问题再次出现。网络分析器显示：ibb.co/Y7V3HHL是同一台计算机，但是另一个用户登录到浏览器（通过“以其他用户身份运行”选项）：ibb.co/QXhsfZP
