only the first 2 parameters are required, the cookie name, the cookie
value. Cookie time is in milliseconds, so the below expires will make the
number you pass in the Set_Cookie function call the number of days the cookie
lasts, if you want it to be hours or minutes, just get rid of 24 and 60.

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.
