Under what circumstances can a value passed by an asp to the next page persist on the next page?

Cookies can be passed to the page, cookies are written, and the cookie expires when left on the page, but if there is no condition that the value is invalid, the value can be passed by url.

If you use post or get to pass it as long as it is not closed, if you use session to pass it to see the default expiration time of the session set is 20 minutes, if you use apliction to send the server as long as it does not restart, and all users are the same, if you use cookies as long as the cookie does not expire it will not disappear.

For example: **

dim id

id = 1

Question mark passes. **》dim id

id = trim("id"))
