服务器启动时无法访问是什么原因造成的？
我已经运行rhc tail我的应用程序来监控新日志。
这是我的日志 http://laravel.io/bin/Dez4o
当我使用启动应用程序时rhc app-start

... other assets
但加载后日志继续

(my.sever.ip.address) - - [26/Jul/2016:21:53:33 -0400] 302 "GET / HTTP/1.0" 364 "-" "-" "-"
然后我执行了rhc app-stop停止服务器
这些是执行“stop”后的日志

所描述的行为与 haproxy 的 http 健康检查相符。由于 haproxy 在健康检查之间不保留 cookie，因此会创建新会话，因此您的应用程序 (Laravel) 会将该请求视为新浏览会话的第一个请求。
您可以将健康检查网址重新配置为不使用会话的网址，以避免创建会话文件，但这意味着即使会话功能中断，健康检查也会通过。
“inter”参数设置两次连续健康检查之间的间隔（以毫秒为单位）。如果未指定，则延迟默认为 2000 毫秒。
