Redirect apache request to another domain

if you have example portal.tenerife.com portal.mazaredo.com portal.antolines.com and you want to redirect it to www.mazaredo.com in httpd.conf put this line RewriteEngine on RewriteCond %{HTTP_HOST} !^portal\.!^\.com$ [NC] RewriteRule ^(.*)$ http://www.mazaredo.com/$1 [R=301,L] As you can see the the url has 3 parts    portal, domain, com  !^portal\.!^\.com$ first part is !^portal\     you can also remove portal so any .com request going to your site will be redirected. second part is !^\ where it is like * anything. last part is .com$
