A little help with managing session timeouts

Hi everyone,

If anyone can help me with the following I would be very greatful.

In order to determine when a session has timed out I have some code in each
page that does something like:

loadSessionData (); // Populates a variable called sessionState

if(sessionState .currentUser != null){
// Carry on
}

else{
Response.Redire ct("/misc_pages/sessionExpired. aspx");
}

My problem is I often have to send out links in emails that jump right into
the secure section of the site. If a session isnt detected it should quietly
take the user to the login page and then once the user enters their details,
redirect them to the secure page they were trying to get to before. This all
sounds fine in theory but the problem is that the code above just identifies
the fact that there isn't any session information and assumes that the
situation is a session timeout - which it isnt.

So I guess my question is:

How can I easily distinguish between occasions when a user's session has
timed out and occasions when the user has just tried to jump into a secure
area of the site without logging in?

If anyone can help me I would be very greatful.

Thanks in advance everyone

Kindest Regards

Check out "Session.IsMewS ession" in the .NET docs. It sounds like what you
want.

Look into FormsAuthentica tion. It should allow you to do most of what you
would like to do.

Hi Guys,

Thanks for your help. I'm currently using forms authentication at the
moment. I can't find much information about session handling in the
documentation though.

I'll go have a look at isSessionNew just now. I'm not sure its what I need
but maybe.

Thanks for your help

Hi Brad,

I think I see where you're going with the IsNewSession property. I just want
to check something with you if thats ok.

Is the reason this works because when a user follows a link to a secure area
of the site from an email, the IsNewSession property will always be true
because it will have been made as soon as the user followed the link. A time
out won't occur like this because the IsNewSession will be false?

That seems to make sense to me. I'll try it later on today.

Thanks again for your help

Hi all, I'm currently relying on logged-in users hitting "logout" (logoff) before they leave, in order to terminate the session. With PHP the session filename is in a cookie that lasts for the current session. The problem is that the server does not know when the current session expires. (I have quite long timeouts.) Did anybody attempt a script to automatically call "logout" when the session expires? It seems quite complicate, as...

Hey. What is the best practice for dealing with session state timeouts in a web app? eg Session_OnEnd Sign them out, so they redirect to Login on the next request. Also, for lower security situations, like a home shopping site used from a secure home environment, how long should the session timeout be? Cheers Justin Dutoit

Hi, I need a quick solution to make my application behave correctly when one of these timeouts occurs. I have some logic in session_start but when the authentication cookie timeouts the user is redirected to login page and after successful login the session is not started. I'd like to have one timeout and when it occurs the user must login and then the new session is started. TIA. Regards, mircu

I use forms based authentication and I've been putting the username in Session State (Session). Then when a user posts I check that Session != null else I Session.Abandon() and Response.Redirect("logon.aspx") since that seems like a graceful way to handle timeouts, session state losses (bin directory was updated for example). This doesn't seem like a reliable way to do it though. I get weird things happening like SOMETIMES if I close...
