I need to redirect a site in a sub-folder to another domain, so, inside the sub-folder I put the following .htaccess file:
Redirect 301 / http://www.newdomain.com/
Redirect directive automatically appends original path to target. Use
RedirectMatch instead in your subfolder:
RedirectMatch 301 / http://www.newdomain.com/
Make sure to clear your browser cache before testing this.
