View 3 RepliesI'm using ASP.NET Session State to keep track of logged in users on my site. However, one problem I'm running into is that by default ASP.NET session cookies are set to expire when the browser closes. I've tried setting my own ASP.NET_SessionId cookie and modifying the cookie's expiry using something similar to the following code:
Response.Cookies["ASP.NET_SessionId"].Expires = DateTime.Now.AddMonths(1);
None of these approaches work, they all set a second cookie with the same name. Is there a way of changing the session cookie's expiry?
Using ASP.NET 2.0, with forms authentication.
Just for a test, I configured the roles cookie in web.config like this :
<roleManager enabled="true" cacheRolesInCookie="true" cookieName=".ASPXROLES" cookieTimeout="2"></roleManager>
I wanted to see what would happen when the cached role cookie expired. Using Fiddler, after 2 minutes had elapsed, I could see that the raw value of the role cookie had changed.
I was expecting that on expiry, that ASP.NET would simply re-read the roles information from the database, and repopulate the cookie with the same value. So my question is, why would the raw value of the cookie change after expiry ? The cookie value is not human-readable (base 64 encoded and/or encrypted ?), so I can't tell if the information in it is the same, although the application still seems to work fine.
EDIT :
It looks like each time the roles are encrypted and cached in the cookie, it gets a different raw value.
e.g. if you run the following code :
RolePrincipal rp = (RolePrincipal) User;
string str = rp.ToEncryptedTicket();
Label1.Text = str;
I have the a test harness detailed below. This has two labels on the page that are set within the page_load which is hit every second due to the updatepanel and timer.
Label1 is set to a datetime value that is stored in the Cache. Label2 is set to the current datetime.
The cache is set with an absolute expiry of 5 seconds from now and there is an update callback on the cache to re-set the datetime and make it valid for another 5 seconds.
The problem I have is that I'm seeing the cache update every 20 seconds, not every 5 seconds like I would expect. If I set the time to 30 seconds then it updates every 40.
This appears to indicate that the cache will only expire every 20 seconds. Does anyone know of a way of reducing this time? If I just insert into the cache with an expiry of 5 seconds and no Callback then it works as I would expect and is removed every 5 seconds.

View 2 RepliesI want to be able to log when a user ends their session on our application and record whether it was a sign out or a the session expired. I am using
cookies.Add(new HttpCookie("ASP.NET_SessionId", ""));
to set a new sessionId on sign out, but when the session expires, the sessionId is reused if the browser instance is not closed. In my web.config I have used
<sessionState mode="InProc" timeout="1" cookieName="session" regenerateExpiredSessionId="true" />
but still get sessions reused. I can't kill the cookie in Session_end() because I don't have access because there is no HttpContext or request, so I can't reset it that way. how I can force a new sessionId from the Global.asax.cs file?
