subdomain rewrite problem

[burhankhan]

Hi:

 

I am using the following .htaccess code for virtual sub domain, and it is working fine:

Options +FollowSymlinks

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www [NC]
RewriteCond %{HTTP_HOST} ^([^.]+)\.st-rt\.com [NC]
RewriteRule ^$ /page/index.php?id=%1 [L] 

 

It is redirecting username.domain.com to www.domain.com/page/index.php?id=username

 

But what to do for this:

username.domain.com/mail.php?id=23

 

I want it to redirect to : www.domain.com/page/pages.php?id=23

 

What to add in .htacess?

 

Thanks
