我在同一台服务器上托管了两个laravel应用程序。
例如。dev.example.com和staging.example.com这两个站点都提供vuejs站点devfh.example.com和stagingfh.example.com可以访问的API。这两个站点都工作得很好，但是，偶尔/随机地，我们在dev site中获得staging数据，在staging site中获得dev数据。
我们使用以下技术：
apache 3.2.2.2版
php 7.3.12版
aws rds for mssql（两个db dev和staging在同一个示例上）
用于存储会话缓存的redis（我们尝试禁用dev站点的redis缓存，但问题仍然存在）。
我觉得这可能是apache、redis或mssql端的缓存问题，或者php操作码缓存不确定。
我们不确定如何进一步调试这个问题。
