This is a deceptively simple method of password protection. The password is the name of the file! In this case, the file that is protected is called target.htm, so the password is target (case is important on this server, but may not be on others). It works because there is no indication in the source of the file name, so unless a visitor knows the file name/password, they will not be able to get in. Simple!
Note: if your protected page is in a subdirectory, make sure that that subdirectory has an index.htm or default.htm file (depending on the type of server) in it, or visitors will be able to find out the name of the file by typing in the URL of the subdirectory and getting a list of the files.
