目前，我使用htaccess的有一个网址系统是这样的：

Currently, I'm having an url system like this by using the htaccess:

- www.domain.com/member/username
- www.domain.com/member/username/contact
- www.domain.com/member/user/album/title-of-the-album/albumID

......这样的事情

.. something like that

下面是我的htaccess的，它完美地工作。

Here is my htaccess, and it worked perfectly.

RewriteRule ^member/([a-zA-Z0-9_-]+)$   member.php?username=$1
RewriteRule ^member/([a-zA-Z0-9_-]+)/contact$   contact.php?username=$1
RewriteRule ^member/([a-zA-Z0-9_-]+)/album/([a-zA-Z0-9_-]+)/([0-9]+)$   album.php?username=$1&title=$2&album_id=$3

现在我想建立一个动态的子域名系统的用户，喜欢username.domain.com 所以我决定用下面的htaccess的：

Now I want to setup a dynamic subdomain system for the user, likes "username.domain.com" So I decided to used the below htaccess:

RewriteCond %{HTTP_HOST} !^www.domain.com
RewriteCond %{HTTP_HOST} ([^.]+).domain.com [NC]
RewriteRule ^(.*)$ www.domain.com/member/%1 [L]

但是，这将用户重定向，而不​​是www.domain.com/member/username他们的旧域www.domain.com/member/username 我想保持username.domain.com（没有URL在地址栏的变化）的用户服务。

But this redirect the user to their old domain "www.domain.com/member/username" instead of "www.domain.com/member/username" I want to keep the user stay in "username.domain.com" (no url change in the address bar).

如果可能的话，是否有任何机会，以保持相同的结构等新的URL，当我输入，如：

If possible, is there any chance to keep the same structure for other new url, such as when I type:

在username.domain.com/contact将载入www.domain.com/member/username/contact（在地址栏中没有URL变化）内容 在username.domain.com/album/title-of-the-album/albumID将载入www.domain.com/member/username/album/title-of-the-album/albumID的内容（在地址栏中没有URL变化）

请帮助！

推荐答案

尝试：

RewriteCond %{HTTP_HOST} !^www.domain.com
RewriteCond %{HTTP_HOST} ([^.]+).domain.com [NC]
RewriteRule ^/?$ /member.php?username=%1 [L]

RewriteCond %{HTTP_HOST} !^www.domain.com
RewriteCond %{HTTP_HOST} ([^.]+).domain.com [NC]
RewriteRule ^/?contact$ /contact.php?username=%1 [L]

RewriteCond %{HTTP_HOST} !^www.domain.com
RewriteCond %{HTTP_HOST} ([^.]+).domain.com [NC]
RewriteRule ^/?album/([a-zA-Z0-9_-]+)/([0-9]+)$ /album.php?username=%1&title=$1&album_id=$2 [L]
