This script will provide a very simple cookie-based single-password login without usernames.
The password is defined in this file, so you need to make sure that nobody will see the source.
Edit the variables to suite your needs. This is a very simple solution and should only be used for
private websites and such. Do NOT use this if you need to store sensitive data, as this is really,
really (!) not a secure way to do it !!! This login will only keep regular visitors from the stuff
you don't want them to see.
Cheerio!
