# Stopping a redirect in .htaccess

This is a real novice question regarding .htaccess files. I have read up on it but I really have no clue.

We have a site called originalsite.com.au that is redirecting to www.examplesite.org.au (see below). When I take the comment out, it redirects fine, when I put the comment back in it goes to a blank page and not back to the originalsite homepage.

I want originalsite.com to point the original home page now. I know the originalsite homepage is there because when I use the IP address instead of the URL it goes to originalsite home page.

I obviously don't understand how .htaccess works. Any help would be appreciated.

RewriteCond %{REQUEST_FILENAME} !-f
