http重定向https
redirect tmp / https://www.a.com/
redirct permanent https://www.a.com/
解决产生循环跳转的问题
RewriteEngine on
RewriteRule ^(/.*)$ https://%{HTTP_HOST}$1 [redirect=302]
两次请求不安全，要用到下面的技术解决
HSTS
HSTS:http strict transport security
客户端第一次访问httpd服务器，服务器会返回给客户端 HSTS信息，如 “hsts 302 https://www.a.com”,客户端会缓存信息"http https://,再加上缓存时间",第二次访问就直接访问缓存中的路径
Header always set Strict-Transport-Security "max-age=31536000" --以秒为单位，缓存一年时间
