为什么我的子域名重定向到我的主要领域？我的、重定向、领域、域名
因此，基本上，我有一个子域， m.mydomain.com.au 虽然我每次访问它，我重定向到 WWW。 mydomain.com.au/m 。
例如，如果我试图去 m.mydomain.com.au/contact.php ，我是自动重定向到 WWW。 mydomain.com.au/m/contact.php
我从来没有尝试之前修改我的的.htaccess 文件，但我相信这是目前造成问题的原因。
所有帮助和建议，大大AP preciated。
下面是我的全的.htaccess 文件：

的RewriteCond％{} REQUEST_FILENAME！-f
的RewriteCond％{} REQUEST_FILENAME！-d
重写规则。*的index.php [L]
解决方案
假设这两个子域和主域名具有相同的文档根目录（因此使用相同htaccess文件），这是造成重定向规则：
的RewriteCond％{HTTP_HOST}！^ WWW .mydomain .COM .AU
重写规则^（。*）$ http://www.mydomain.com.au/$1 [R =永久，L]
这基本上是说，如果访问的不可以 www.mydomain.com.au ，重定向到 HTTP ：//www.mydomain.com.au/
您需要添加额外的检查，以便它不重定向你的子域名：
的RewriteCond％{HTTP_HOST}！^ WWW .mydomain .COM .AU $ [NC]
的RewriteCond％{HTTP_HOST}！^ M .mydomain .COM .AU $ [NC]
重写规则^（。*）$ http://www.mydomain.com.au/$1 [R =永久，L]
或者只是重定向没有 WWW的域名：
的RewriteCond％{HTTP_HOST} ^ MYDOMAIN .COM .AU $ [NC]
重写规则^（。*）$ http://www.mydomain.com.au/$1 [R =永久，L]
So basically, I have a subdomain, m.mydomain.com.au although every time I visit it, I am redirected to www.mydomain.com.au/m.
For example, if I attempt to go to m.mydomain.com.au/contact.php, I am automatically redirected to www.mydomain.com.au/m/contact.php
I have never attempted to modify my .htaccess file before, but I believe it is causing the problem at the moment.
All help and suggestions is greatly appreciated.

解决方案
Assuming that both your subdomain and main domain have the same document root (and thus use the same htaccess file), this is the rule that's causing the redirect:
RewriteCond %{HTTP_HOST} !^www.mydomain.com.au
RewriteRule ^(.*)$ http://www.mydomain.com.au/$1 [R=permanent,L]
This essentially says, if the domain is not www.mydomain.com.au, redirect it to http://www.mydomain.com.au/.
You need to add an additional check so that it doesn't redirect your subdomain:
RewriteCond %{HTTP_HOST} !^www.mydomain.com.au$ [NC]
RewriteCond %{HTTP_HOST} !^m.mydomain.com.au$ [NC]
RewriteRule ^(.*)$ http://www.mydomain.com.au/$1 [R=permanent,L]
Or only redirect the domain without the www.:
RewriteCond %{HTTP_HOST} ^mydomain.com.au$ [NC]
RewriteRule ^(.*)$ http://www.mydomain.com.au/$1 [R=permanent,L]
