今天在使用https面板时候遇到一个问题设置了301重定向，
但是https://liugang.net不会自动跳转到https://www.liugang.net
注意要先开启https，再配置跳转
已可以在配置文件中手动修改
<VirtualHost *:443>里面加入一行
IncludeOptional /www/server/panel/vhost/apache/redirect/www.liugang.net/*.conf
注意这一行不同站点是不一样的，可以在<VirtualHost *:80>里面复制即可
php应用实现webSocket更多使用workerman或swoole框架.
