301 redirect for a subdomain

Hi,
I have site and  i have subdomian in that site too.. i have  4 subdomains but the subdomains in the same one- www.(dot)subdomain(dot)domain(dot)com
how to redirect in a proper way..please help me

To redirect a given domain/subdomain to another domain, add the following to your .htaccess file:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^subdomain.domain.com
ReWriteRule ^/?(.*)$ http://targetdomain.com/$1 [L,QSA,R=301]

This will redirect subdomain.domain.com/some/path to targetdomain.com/some/path

Look up the docs for RewriteRule if you want to do anything more complicated. You can repeat the RewriteCond/RewriteRule pairing (with appropriate domain names) for each domain you want redirecting.

anthonyw give you a very good suggestions. I think this is the way you can redirect in a proper way.   

use htaccess and write a redirect rule
