Isaiah's Cookie Demo

This demonstrates how a COOKIE works.

Submit will write a COOKIE to your computer using the first and second variables you provide below.
Refresh will read the COOKIE from your computer and display contents below.
Delete will delete the COOKIE from your computer.
Additional note -- the COOKIE will automatically expire in 60 seconds. To see this happen, wait 60 seconds and Refresh

The current value of the cookie is:
