only the first 2 parameters are required, the cookie name, the cookie

number you pass in the Set_Cookie function call the number of days (by default) the cookie
lasts, if you want it to be minutes pass 'mins', hours pass 'hrs' etc.
Valid units are 'mins', 'hrs', 'days', 'wks', 'yrs'
Anything else will default back to days.

Generally you don't need to worry about domain, path or secure for most applications
so unless you need that, leave those parameters blank in the function call.
