Two ways to keep session data:

• URL Stuffing: place a key in the URL
• But, you lose data when the browser is shut down.
• Use with a sign-in.
• Cookies: write a key on the user's computer
• Recognize the user immediately when the browser is opened.
• Use with sign-in to keep data among different computers.
• But... Cookies are highly misunderstood.  Can only write text.
• Many people turn off cookies.
• Why keep session data, anyway?
