Set various cookie expiration times
The default cookie expiration time is until the browser is closed, and the cookie expires. You can also specify the cookie expiration time.
Response. Cookies ("user_name"). expires = date + 1 'specify the cookie retention time
Keep cookies for one hour
Response. Cookies ("mycookie"). expires = (now () + 1/24)
Response. Cookies ("mycookie"). expires = dateadd ("H", 1, now ())
Set expiration time after 60 months
Response. Cookies ("cookiename"). expires = dateadd ("M", 60, now ())
Response. Cookies ("user"). expires = second () + 7
The time defined after expires can be replaced by the time function.
For example, date () + 7 means that seven days are added to the current time, while second () + 7 means 7 seconds.
Response. Cookies ("field name"). expires = Time Function + N,
For example, response. Cookies ("name2"). expires = date + 1 indicates that cookies are saved for one day,
For another example, response. Cookies ("name2"). expires = hour + 8 indicates that cookies are stored for 8 hours.
I can't test this method (in 2003 Server, iis6.0), no matter whether or not the second is followed (),
A 500 error occurs during access (or cannot the webpage be displayed? Forgot ).
Zhimeng Juventus: We recommend that you use the dateadd function to accumulate the time here. For example, we need to accumulate an hour,
Use: Response. Cookies ("Your dooglecom"). expires = dateadd ("H", 1, now () 30 minutes:
Response. Cookies ("cookiename"). expires = dateadd ("N", 30, now () dateadd ("S", 30, now ())
The expiration date of the cookie specified by the second expires is obtained. To store cookies on the client disk after the session ends,
Or in many cases, we want to save cookies on the visitor's computer for a longer period of time. This date must be set.
If the setting of this attribute does not exceed the current date,
The cookie will expire after the task ends. The cookie expiration date is "January 1, January 1, 2010 ":
Response. cookies ("cookiename "). expires = # January 01,201 0 # The cookie expiration time is "Cookie creation time + 365 days": response. cookies ("cookiename "). expires = date + 365, but it is best not to write response at will. cookies ("cookiename "). expires = date,
In this way, the call time value between pages will be blank.
