Cookies assignment, read, delete set expiration time

Set Expiration Time
Response.Cookies ("Visiter"). Expires=dateadd ("H", 8,now ()) ' means Cookies kept for 8 hours
Response.Cookies ("user_name"). Expires=date 1 ' Specify Cookie save time
Keep cookies for one hours
Response.Cookies ("MyCookie"). Expires= (now () 1/24)
Response.Cookies ("MyCookie"). Expires = DATEADD ("h", 1, Now ())

Response.Cookies ("CookieName"). Expires=dateadd ("M", 60,now ())
Set expires after 60 months
Response.Cookies ("User"). Expires=second () 7
The time defined after expires can be replaced with a time function
For example: Date () 7 means adding 7 days to today's time, and second () 7 is 7 seconds.
Response.Cookies ("field name"). expires= time function N, for example:
Response.Cookies ("Name2"). Expires=date 1, which means that Cookies are kept for 1 days, and then for example:
Response.Cookies ("Name2"). Expires=hour 8, which means Cookies are kept for 8 hours.
I have not tested this method (in 2003server,iis6.0), regardless of the second after the addition (), access to a 500 error (or the page can not be displayed?) Forgotten).

The time added here is to use the DATEADD function, for example, if we add an hour, we use:
Response.Cookies ("Baidooglecom"). Expires = DATEADD ("h", 1, Now ())
30 minutes:
Response.Cookies ("CookieName"). Expires=dateadd ("n", 30,now ())
DATEADD ("S", 30,now ()) Get seconds

Response.Cookies ("visiter") = "AAA"
A=request.cookies ("Visiter")
Response.Cookies ("Letwego") ("visiter") = "AAA"
A=request.cookies ("Letwego") ("Visiter")

Response.Cookies ("Letwego") ("visiter") = "84WW" ' Assignment
Response.Cookies ("Letwego"). Expires= (now () 7) ' Set Expiration Time (7 days)
Username=request.cookies ("Letwego") ("Visiter") ' Take Cookies
Response.Cookies ("Letwego"). Expires= (Now ()-1) ' Delete cookies, set expiration time (-1 days)
' DateAdd ("n", 30,now ()) Get minutes
' DateAdd ("S", 30,now ()) Get seconds
