Question

I just saw in my browser a cookie with the name ASP.NET_SessionId and an expiration of “When I close my browser”.

From where this expiration time coming, and how can I configure it?

Answer 1

asp.net sets a cookie which is NOT PERSISTENT – meaning you didn’t set any Expiration time.

So the expiration time is when you close the browser.

If you set expiration time – it goes from the memory area into the Hard Drive as a file !

expiration is set ? yes

in Hard Drive as a file.
this is called persistent

expiration is set ? no

this is called non-persistent as ASP.NET_SessionId cookie in memory.

expiration setting - how ?

Response.Cookies["userName"].Value = "patrick";
Response.Cookies["userName"].Expires = DateTime.Now.AddDays(1);
