Description of Indigo Link Guard :
This script is not like like many others. This script does not require constant editing or any admin console to add files. Just put the files in the protected folder and place a link to them on your site and Indigo Link Guard does the rest. Unlimited domain support! Folder masking! All that in just 1 simple script. Instructions are inside the single script to make it easier to know what 2 lines of code to edit. This is the simplest link guard script available.
