argumento subdominio .htaccess no es accesible en la cadena de consulta

Question

He escrito las siguientes reglas en .htaccess

RewriteCond %{HTTP_HOST} ^([^\.]+)\.domain\.com 
RewriteCond %1 !^www$ [NC] 
RewriteCond %{REQUEST_URI} ^/news/news-details\.php$ 
RewriteRule (.*) news.php?div=%1 

Lo que hace es transferir la solicitud al archivo news.php con el div variable igual a news/news-details.php. No necesito que el div sea así. Necesito el valor del subdominio que se ha escrito con el dominio, como si el usuario proviene del user.domain.com/news/news-details.php. Necesito la variable div en el archivo news.php para ser usuario, es decir, news.php?div=user.

EDIT: Aquí es ahora el código .htaccess Está causando un problema para las opciones de la página detalles de noticias raíz

# For Accessing News Details Page for root http://www.domain.com/news/news-details.php 
RewriteCond %{HTTP_HOST} ^www.domain\.com [NC] 
RewriteRule ^news/news-details.php$ news.php [QSA,NC,L] 


# For Accessing News Details Page http://user.domain.com/news/news-details.php 
RewriteCond %{HTTP_HOST} ^(.+)\.domain\.com [NC] 
RewriteCond %{HTTP_HOST) !^www\. 
RewriteRule ^news/news-details.php$ news.php?div=%1 [QSA,NC,L 


# For www.domain.com it should go to the index page 
RewriteCond %{HTTP_HOST} ^(www\.)?domain.com$ [NC] 
RewriteRule ^(.*)$ index.php [NC,L] 


# For Accessing Divisions Page user.domain.com should go to domain.com/divisions.php?division=user 
RewriteCond %{HTTP_HOST} !^www\.domain\.com$ 
RewriteCond %{HTTP_HOST} ^(.*)\.domain\.com$ 
RewriteRule ^$ /divisions.php?division=%1 [L] 

DE NUEVO EDIT:

Aquí estas dos reglas son conflictivos

# For www.domain.com it should go to my-index.php page 
# 
RewriteCond %{HTTP_HOST} ^(www\.)?domain\.com$ [NC] 
RewriteRule ^(.*)$ my-index.php [NC,L] 


# For Page URL http://www.domain.com/news/news-details.php 
# 
RewriteCond %{REQUEST_URI} ^/news/news\-details\.php [NC] 
RewriteCond %{HTTP_HOST} ^www\.domain\.com$ [NC] 
RewriteRule ^(.*)$ my-news.php [NC,QSA,L]

Pruebe esto:

RewriteCond %{REQUEST_URI} ^/news/news\-details.php$ 
RewriteCond %{HTTP_HOST} ^([a-z0-9]+)\.domain\.com$ [NC] 
RewriteCond %1 !^www$ [NC] 
RewriteRule ^(.*)$ news.php?div=%1 [NC,QSA,L] 

RewriteCond %{REQUEST_URI} ^/news/news\-details\.php [NC] 
RewriteCond %{HTTP_HOST} ^www\.domain\.com$ [NC] 
RewriteRule ^(.*)$ news.php [NC,QSA,L] 

RewriteCond %{HTTP_HOST} ^www\.domain\.com$ [NC] 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteRule ^(.*)$ index.php [NC,QSA,L] 

RewriteCond %{HTTP_HOST} ^([a-z0-9]+)\.domain\.com$ [NC] 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteRule ^(.*)$ divisions.php?division=%1 [NC,QSA,L]
