问题描述
限时送ChatGPT账号..我正在处理一个网页(我们称之为 example)并在 CNAME(别名)下添加了 DNS 记录:
I'm working on a webpage (let's call it example) and added the DNS record under CNAME (Alias):
Host Record Points to TTL
www example 14400
但是,当我浏览 example 时,如果我转到 www.example,则不会保留设置的会话变量
However when I navigate through example, the session variables that are set are not retained if I go to www.example
让 www.example 和 example 使用相同会话变量的最佳方法是什么?
What is the best way to make www.example AND example use the same session variables?
我使用的是 ubuntu 12.04、php5、apache2.

最好的方法是不要让两个主机名运行同一个站点.
The best way is to not have both host names running the same site.
选择其中一个作为规范,然后将所有内容从另一个重定向到规范的.
Pick one of them to be canonical, then redirect everything from the other to the canonical one.
<VirtualHost *:80>
ServerName example
Redirect 301 / http://www.example
etc
