Response.Cookies("UserName") = "joe"

correct me if i am wrong but it looks like "joe" is being set to the cookie "UserName"..
I am looking at the windows\cookies\ folder and I dont see any cookies with those values or names.


Then I put this in another asp page.

Response.Write Request("UserName")

Every time i go to that page, "joe" is being displayed.. Is there a way that i can code it so "joe" will ONLY be displayed upto 15 mintues it was set?
