In order to redirect your domain to another one,
Create .htaccess in the root of the domain you want redirect and put in it:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^developers-heaven.net$ [OR]
RewriteCond %{HTTP_HOST} ^www.developers-heaven.net$
Rewriterule ^(.*)$ http://developers-heaven.com/$1 [r=301,nc]
This means developers-heaven.net will redirect you to developers-heaven.com
