I have drupal on http://ikhnaton2.com/whisper. I created a subdomain called http://whisper.ikhnaton2.com. I need to redirect request from http://whisper.ikhnaton2.com/{path} to http://ikhnaton2.com/whisper/{path}. I add the following lines to .htaccess in /www (which is the DocumentRoot) to do the redirect:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^ikhnaton2\.com$ [OR]
RewriteCond %{HTTP_HOST} !^www\.ikhnaton2\.com$ [OR]
RewriteCond %{HTTP_HOST} !^whisper\.ikhnaton2\.com$ [OR]
RewriteCond %{HTTP_HOST} !^www.whisper.ikhnaton2\.com$ [OR]
RewriteRule ^(.*)$ http://www.ikhnaton2.com/whisper/$1 [R=301,L]

Results:
Requests for: http://ikhnaton2.com or http://www.ikhnaton2.com -> go to: http://www.ikhnaton2.com/whisper/ successfully

Requests for: http://ikhnaton2.com/{anything} or http://www.ikhnaton2.com/{anything} -> goes to: http://www.ikhnaton2.com/whisper/ successfully

Requests for: http://whisper.ikhnaton2.com/{anthing} or http://www.whisper.ikhnaton2.com/{anything} doesn't go: http://www.ikhnaton2.com/whisper/{anything}

What I'm missing here?!!! Appreciate any help coz I gave up
