mod_rewrite condition and rule - apache

Question

I've searched for this and Im probably just sitting to close but I cant seem to get this rewrite to work. I have a file on a directory that I want to redirect to a vhost domain on the same server. Below is my condition, rule, and vhost
RewriteCond %{HTTP_HOST} ^/main$ [NC]
RewriteRule ^(.*)$ http://domain.com/$1 [R,l]
<VirtualHost *:80>
ServerName www.domain.com
ServerAlias domain.com
DocumentRoot /data/live/main
</VirtualHost>

If you want to redirect the olddomain folder main to the newdomain then you can use:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.olddomain\.com$ [OR,NC]
RewriteCond %{HTTP_HOST} ^olddomain\.com$ [NC]
RewriteRule ^main/(.*)$ http://newdomain.com/$1 [R=301,L]
If you want to redirect all the content of the olddomain to the newdomain then you can use:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.olddomain\.com$ [OR,NC]
RewriteCond %{HTTP_HOST} ^olddomain\.com$ [NC]
RewriteRule ^(.*)$ http://newdomain.com/$1 [R=301,L]
And if you want to remove the www from your newdomain:
RewriteCond %{HTTP_HOST} ^www\.newdomain\.com$ [NC]
RewriteRule ^(.*)$ http://newdomain.com/$1 [R=301,L]
Or you can do it directly on the virtualhost like this:
<VirtualHost *:80>
ServerName newdomain.com
Redirect permanent / http://www.newdomain.com
DocumentRoot /data/live/main
</VirtualHost>
