Detect If Session Expired Using Javascript?

Jul 22, 2010

I am creating a web application using ASP.Net. I am using session in my application.

There is one scenario where I am trying to access session variable through Javascript. It is working fine, when I m accessing it in normal state. But after session expiry, if click on any button, it throws exception and behaves abnormally, resulting in page not found.

Here is the code I am using;

var TransactionID = '<% =((Hashtable)(Session["SessionData"]))["TransactionID "] %>';
if(TransactionID !='')
{
//action
}

I am trying to achieve something like of sort in c#;

String lsStr;
if(null != lsStr)
{
//action
}

How To Detect If SessionState Has Expired

Nov 9, 2010

What would be the best way to detect if the SessionState has died in order to send the user to a "Session Expired" page? I've successfully configured the app (in Web.config) to do this when the authentication cookie is gone (there's a setting for that), but so far I haven't found an effective way to do something similar when the SessionState is gone. The app in question holds some data in the Session, and should present the user with a "Session Expired - login again" page if any of them is gone.

So far, the only option I can think of doing it in each of the places I access Session, but this is obviously a less than optimal solution.

Detecting An Expired Session From Php?

Feb 23, 2011

I'm developing an extra section to a web app that's written in asp.net, but in php - it's mostly done (the two parts don't really communicate with each other outside of a database - the integration is mostly just cosmetic.)

The only issue I have is detecting from the php part when the .net session has expired so that it logs the user out and redirects to the login page.

I believe the asp.net application is compiled, but either way I'm not allowed to alter it so I was thinking maybe the best thing to do would be to make a very small/simple aspx page that outputs true or false which I could call using curl from php (and passing the browser's cookies along.)

Would this even be possible? I'm not sure how session security works on asp.net eg whether one .net application can read another's session variables, but if it's anything like php then it'll be possible.

mypage.php --curl--> checksession.aspx --|
| |
<----------- true / false <---------------

So mypage issues a GET (with cookies from browser) to checksession using curl, checksession simply returns a true or false (or something like that) and mypage redirects to the site's login page if that's false.

The authentication for the php side is already sorted out and is separate to this issue.

So really, what I need to know is can I have just a simple .aspx file that does this check, and if so where would I go to to find out how to program such a simple page?

Session Gets Expired Using Third Party Dll's For Pdf Publishing

Mar 28, 2011

The Scenario:
I have a situation where I need to pass some session variables to an ASPX page, inside a DNN module. This page is then transferred to Winnovative's PDF publishing component's in the form of a byte array. The component returns a PDF document in the result, furthermore that PDF document is then emailed to the customer.

The Problem:
The session gets expired when the ASPX page is called (hosted as a part of DNN web project on IIS) to pass it to Winnovative. It was noticed that the session expired when ever I request the page (by any means) and a new session on that page is created.

Is there any workaround (without involving a database) that I can access those session variables (it is a dataset) from that particular ASP.NET page?

I receive the error message "Error: Your session has expired. Please refresh your browser." When I export a table in ASP to Excel. I know for a fact that the correct data to export exists.

Website Occasionally Being Redirected To Login Page Even Though Session Not Expired

Oct 27, 2011

What might cause this? Seems to be happening at random on a site I created. A user will for example be filing in a form, and when they click Save, it will flash to the login page as if the session has expired, but it will still show them logged in, and if they click back and save again it will work. It's not confined to the one page either, it just seemingly at random acts like the session has expired when it hasn't.

Security :: User.Identity.IsAuthenticated Returns True But Session Has Expired

May 24, 2010

I have a page where, when the user has successfully logged in, I store some values in the session.

I then use these values to load an application list page. This page is automatically refreshed after 20.1 minutes, with the sessionstate timeout and forms timeout in web.config set to 20 minutes (with sliding expiration). This means, if the user does not use any page for more than 20 minutes, he is timed out.

My problem is that the User.Identity.IsAuthenticated sometimes returns true, when the session has expired.

Why is this happening, and how can I fix it?

Configuration :: Session Expired Very Fast / Avoid Change Database From MS Access To SQL?

Aug 9, 2010

I am currently using the brinkster hosting (Pro Package) but recently they change my hosting to the new one and after that I got an error for sometimes and my session also expired very fast. Below is the feedback from Brinkster.

Thank you for letting us know about your recent experience with your application. From what we are able to find regarding your application problems, they appear to be related to your ms access database. Due to limitations of ms access, you may want to consider updating the database running your website to mysql. A Mysql database is available to your account at no additional charge.

MS access begins to experience issues like database locks (which is what appears to be happening to your application) when there are more than 3 or 4 concurrent connections to the database for reads. MS access is also only able to have one write connection open at any given moment. MS access databases are more susceptible to corruption and data loss than database application built for large application use and Enterprise or corporate use.

When you were hosted on the previous server, your IIS application pool was getting reset many times per day. This action was in effect unlocking your ms access database from its locked state. After we moved you to the new system and raised your memory utilization limit, your application does not receive resets more than one or two times a week. I have lowered your memory utilization from 200 to 100 in an effort to have your application reset more often, unlocking your database if it has began to cause issues.

My question is, do i have a choice to avoid change my database from MS Access to MySQL? Is MS Access database really have such problem as they mension or somethingelse happen on their server?

Trying To Detect Session State Timeout?

Apr 13, 2010

I am trying to detect a session state timeout in my asp.net application and am unable to do so. I have a base class that derives from System.Web.UI.Page as follows:-

public class BasePageSessionExpire : Page
{
override protected void OnInit(EventArgs e)
{
base.OnInit(e);
if (Context.Session != null)
{
if (Session.IsNewSession)
{
string szCookieHeader = Request.Headers["Cookie"];
if ((null != szCookieHeader) && (szCookieHeader.IndexOf("ASP.NET_SessionId") > 0))
{
Session.Abandon();
Response.Redirect("~/SessionExpired.aspx",true);
}
}
}
}
}

All the pages I need session state checking on derive from this base class instead of "System.Web.UI.Page". Also, all these pages have EnableSessionState="True". I have a blank Session_Start() method in my global.asax file if that is relevant at all.

For some reason after the first request, the "Session.IsNewSession" property is always false. It is true only for the first request and then is always false. I have my timeout set to 1 minute. The session never seems to timeout. What am I missing here ?

Also I have implemented a state server in SQL Server 2008. This is not an in-proc session state implementation.
