Apache主机一般支持.htaccess伪静态，即可以实现绑定域名到子目录、一个空间多个站点。
应用举例：绑定htaccess.800m.net到htaccess目录
根目录下.htaccess内容
RewriteEngine On RewriteBase / # 绑定htaccess.800m.net到子目录htaccess RewriteCond %{HTTP_HOST} ^htaccess\.800m\.net$ [NC] RewriteCond %{REQUEST_URI} !^/htaccess/ RewriteRule ^(.*)$ htaccess/$1?Rewrite [L,QSA] #可以绑定多个，只需重复上三行代码并更改一下域名、目录名就行了
即使HTTP_HOST中的“.”不加反斜杠，也能够实现绑定htaccess.800m.net，因为“.”可以匹配任意一个字符。
htaccess目录下的.htaccess内容
RewriteEngine On RewriteBase / #只许绑定的域名访问，其他域名301跳转 RewriteCond %{HTTP_HOST} !^htaccess\.800m\.net$ [NC] RewriteRule (.*) $1 [L,R=301] #对绑定目录下htaccess目录的处理 RewriteCond %{REQUEST_URI} ^\/htaccess\/ [NC] RewriteCond %{QUERY_STRING} !^(.*)?Rewrite #htaccess.800m.net/htaccess实际上访问htaccess.800m.net/htaccess/htaccess RewriteRule ^(.*)$ /%{REQUEST_URI}/%{REQUEST_URI}/$1?Rewrite [L,QSA]
当然，如果对绑定子目录的要求不高的话，子目录下就不需要建立.htaccess文件了。
