我有一个门户网站 http://www.mysite.com/ ，客户报名参加，他们让网站运行我的应用程序自身的子域的版本。 我已经成立了通配符子域DNS /虚拟主机等，并得到它的工作。

I have a portal site http://www.mysite.com/ where customers sign up and they get their own subdomain version of the site to run my app. I've set up the wildcard subdomain DNS/VirtualHost etc and got it working.

我试图建立是我的htaccess文件传递通配符子域作为参数传递给应用程序，像这样的：

What I am trying to set up is my htaccess file to pass the wildcard subdomain as a parameter to the app, like this:

http://wildcardsubdomain.mysite.com/ -> http://www.mysite.com/app/?dj=wildcardsubdomain
http://wildcardsubdomain.mysite.com/?l=genres -> http://www.mysite.com/app/?dj=wildcardsubdomain&l=genres

我在 http://www.mysite.com/

RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.mysite.com
RewriteCond %{HTTP_HOST} ^(.+).mysite.com
RewriteRule ^([^/]*)$ http://www.mysite.com/app/dj/%1 [P,L]

不过，我需要重定向admin用户的网址如下，我已经得到了坚持与htaccess的code到/ app目录内使用。 我需要的是：

But I need to redirect the admin user URLs as follows and I've gotten stuck with the htaccess code to use inside the /app directory. What I need is:

http://wildcardsubdomain.mysite.com/admin/?l=genres -> http://www.mysite.com/app/admin.php?dj=wildcardsubdomain&l=genres
http://wildcardsubdomain.mysite.com/admin/?l=users -> http://www.mysite.com/app/admin.php?dj=wildcardsubdomain&l=users

（第l参数各不相同，我只是用用户和流派在这里作为一个例子）

(the l parameter varies, I've just used users and genres here as an example)

我已经试过这里面/app/.htaccess，但它未果然奏效：

I've tried this inside /app/.htaccess but it hasnt really worked:

RewriteRule ^dj/([^/]+)/?$ $2?dj=$1 [QSA,L]
RewriteRule ^admin/([^/]+)/?$ admin.php$2?dj=$1 [QSA,L]

任何人都可以提出一个更好的重写规则？ 提前非常感谢

Can anyone suggest a better rewrite rule? Many thanks in advance

推荐答案

你错过了一个 QSA 标记，因为 L =类型丢失，否则。你的其他规则之前，你只需要一个管理员的规则：

You're missing a QSA flag, as the l=genres gets lost otherwise. You just need an "admin" rule before your other rule:

RewriteEngine on

RewriteCond %{HTTP_HOST} !^www.mysite.com
RewriteCond %{HTTP_HOST} ^(.+).mysite.com
RewriteRule ^admin/?$ http://www.mysite.com/app/admin.php?dj=%1 [P,L,QSA]

RewriteCond %{HTTP_HOST} !^www.mysite.com
RewriteCond %{HTTP_HOST} ^(.+).mysite.com
RewriteRule ^([^/]*)$ http://www.mysite.com/app/dj=%1 [P,L,QSA]
