I am embarrassed to ask this. If I set a cookie for 30 days, and the
visitor comes back 25 days later but I do nothing to re-set the
cookie, will his cookie expire in 5 days, or does his browser
automatically reset it to another 30 days?
That depends on if you reset the cookie when they come back or not. If
your routines set the cookie only if the cookie does not already exist,
then it would not reset the cookie at 25 days, so it would indeed expire
5 days after that.
If you check to see if the cookie exists first, and then reset the
expiration date at that time, then the cookie would last for another 30
days...
