Steve,

Application vars are great for controlling attributes that occasionally
change (or frequently for that matter) that you want to affect the whole
application.  Say you wanted to have bgcolor across your entire site change
according to the time of day.  You can code your application.cfm or a
header.cfm script to <CFSET Application.BGColor = "whatevercoloryouwant">
based on the time of day.  Then, instead of coding this in the top of each
script,  you can simply call the #Application.BGColor# variable in each
script, and it will automatically be what you want it to be for everyone
calling your application.
