HT Access (401) question

Hi all! I recently discovered a website was frequently visiting one of my directories, in fact they posted a link to it on a website. So I thought I would passpword protect it. I used the Dreamhost set-up for a htaccess and it works great…HOWEVER, when I go back to the site that linked the http…they could still get in. What gives?? Can someone explain this to me. What go is putting a password protect on a directory if someone can still access it. Any help would be great—Many thanks in advance!

Are you sure it wasn’t just you being logged in to the directory already?

DOH!!! I figured it out----might help if I type in the directory name EXACTLY!!! Geeze… Hey, this is a really cool little option…now that I have it figured out…(blush).
