I have seen "No Peeking" pages on some websites when I try to look into a directory (for example a directory of images). Rather than get a list of files that exist in the directory, a page is displayed with a message such as "No Peeking". Is this done with mod_rewrite?
I would like to implement this into a site of mind that has an extensive photo gallery system. However, I want to receive traffic from Google Image Searches, so would like to know if this would affect the Google traffic.
Thanks for any response/help.
