二级域名配置:最简单的php二级域名配置
配置二级域名首先是重定向的问题
在apache打开对.htaccess的支持后，在网站目录下的.htaccess文件中加入
rewritecond %{HTTP_HOST} xx\.domain\.com$
rewriterule (.*)$ /xx/$1
然后在域名提供商那里加入一条DNS A记录就可以完成工作了。
这样访问xx.domain.com，就定位到网站目录xx下。
重定向完毕后，还有session和cookie共享的问题
在php.ini里面找到session.cookie_domain
改为session.cookie_domain =domain.com即可
