i've got a pointed domain keepyourlinks.com on my small cpanel of piscolabis.info, if you visit piscolabis.info/keepyourlinks.com/ you acces it and i'm not going that, i am trying:

RewriteCond %{HTTP_HOST} ^piscolabis.info/keepyourlinks.com/ [NC]
RewriteRule ^(.*)$ http://keepyourlinks.com/$1 [L,R=301]

However it does not work... :S

This will work:

RewriteCond %{HTTP_HOST} ^piscolabis.info$
RewriteCond %{REQUEST_URI} ^/keepyourlinks.com [NC]
RewriteRule ^(.*)$ http://keepyourlinks.com/$1 [L,R=301]
