I am trying to remove the folder /blog/ from the following url:

with:

http://blog.site.com/2011/05/26/article-name-test/

Answer 1

Put this code in your .htaccess file:

Options +FollowSymlinks -MultiViews
RewriteEngine on

RewriteRule ^blog/?(.*)$ /$1 [R=301,L,NE,NC]

Update: Based on your comments

Here is your suggested .htaccess:

RewriteCond %{HTTP_HOST} ^www\.site\.me$ [NC]
RewriteRule ^ http://site.me%{REQUEST_URI} [R=301,L] 

RewriteCond %{HTTP_HOST} ^holisticho\.me$ [NC]
RewriteRule ^blog/ http://blog.site.me [R=301,L,NC]
