Ajax timeout redirect to login again

Posted By:      Posted Date: October 12, 2010    Points: 0   Category :ASP.Net


I have some problems whereby sometimes my application redirects to the login page if the users sessions timesout.

What I'm finding though is that pages that are ajaxified with update panels etc don't appear to redirect to the login correctly.

Meaning that my users come back and click a button and a horrible 'object not set to an instance of an object' error appears.

I was wondering if anyone has a fix for this - or if they recommend some javascript on the page to return the user to login (and therefore load session stuff).

session timeout redirect in ajax calls


If a normal session timeout occurs we could handle the session timeout.

But say we are using a lot of ajax calls, webhandlers etc. How would we catch session timeout here and redirect to error/login page.


I thought this would be simple... Trying to create a login does an ajax check before submit


I have the standard .net login control that is working.  (Still learning .net after 15yrs of classic)

What I want to do is OnButtonClick run a javascript function (to do an ajax call to the db to check if login is valid or not) and if it returns true, then submit the form normally, else don't submit. The piece that I can't figure out, is how to correctly override the default click even to hit my JS routine and then submit the form properly afterwards.

Thanks ahead of time

Ajax Session timeout problem

Hi,  I have some problems when using AJAX with updatepanels. I have an ASP.NET webapplication with a login that uses form authentication with the timeout set to 5 min. After 5 min of idle the site should be redirected to the login.aspx page. My problem is that after using the site for 5 minutes when clicking on contents inside an updatepanel I get a messagebox with the following error: A Runtime Error has occurred.Do you wish to Debug? Line: 4723Error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12031  I think that it has something to do with the ajax updatepanel since when I remove the updatpanels this problem does not appear. Instead the site is redirected to login.aspx as expected. When searching on the problem on google I see alot of people having similar problem, but I haven't found suitable solution. Any suggestions?

Authentication timeout while making AJAX call?

Hi,I tried to take advantage of jQuery AJAX call to enhance user experience but I am facing a tricky problem.When the user does nothing for a period of time, e.g. 30 minutes to reach authentication timeout, making AJAX call becomes the problem. The server side will return login page and display in my target div section. The simplest solution I can think of is to inject a dummy tag in login page, and when detecting such dummy tag then use javascript to redirect to login page. But this means that I have to do that every time I make AJAX call. Is there any more decent way to do that? Regards,Charlie

Session time out alert box and redirect login page


Dear all,

Now I am using Form authentication for my website. 

It is something like that below. But if I left the website without using it for quite some time and when I used it back, it is redirected to the login page. 

The one I want to know is that it is because of session expire or cookies expire. And if it is session expired, I want to show the alert box and redirect to the login page. And one more thing is that if the user keeps on using the website, I want to extend the session expire time. If you do not mind, I want to have some references for this scenario. Thank you so much.

Can I only create session on login and redirect to login from other apps if not using custom provide


I have created custom a MembershipProvider, SessionIDManager, and SessionStateStore since I need to use custom legacy sessions and logins.. When the Application is ran, it runs the GetSessionID in the SessionIDManager(which is correct)..

The problem then is if there is no session meaning the GetSessionID method returns null, it tries to create a new session using CreateSessionID.. I want it to redirect to the login application(another application)..

We only create and store session information for logged in users and the "session id numbers" come from a file that is pre-populated with "session id numbers"(I didnt design this and its out of my control).. So its not feasable to give everyone who visits the site one of the "session id" numbers..

I also need for users with an "invalid" session(when checked through Validate()) to be redirected to the login page..


Any help here would be great..

After Login , Redirect To Previous Page Instead Of Destination URL set


Hi .

I have developed an asp.net project with asp.net membership for login.

I have login control in a page and for that I have set the property destination URL to a particular page say defaultlogin.aspx.

It is also working fine, when I use to login from home page.

But if i navigate to different pages of my website say first to home page, contact us page, about us page etc. Then after that when I click on login page and key up the login information in the login control.

I use to redirect to the last page which I have visited the last. It is not redirecting to the destination page which I have set in the login control.

What's the problem here?

Plz help me with the above issue.

Thanx in advance.

Redirect User After Timeout?


How can I redirect the user to the first page when they've been idle for more than 20 minutes or so?

Here's my session timeout time in my web config file:

<sessionState timeout="20"/>



hyperlink in Excel and login redirect


The user has a .xlsx with links pointing to a portal page witch require user logon.

First time (clicking on a link) the login.aspx?ReturnUrl=... is displayed, as expected. User logs in.

Second time, login.aspx?ReturnUrl=... displayed again, wrongly, bec user is already loged on.

It's seems, Excel calls the original link directly, server redirects (bec, excel is not loged in), than excel lunch the browser with new redirected url.

I can't simply redirect the user automatically, bec login.aspx is displayed also when the user has no permmissons.

What can I do?


Login redirect to different pages



I'm new to this forum (was always a reader, not a poster). And I'll hope to learn alot here.

I have to admit, I'm a total newbie to the ASP programming language.

Now onto my problem: I want to make a login, which redirects to different pages bound to the username after the login

I already tried solutions offered on : http://forums.asp.net/t/1079990.aspx?PageIndex=1

So basically what I want is for example this:

I have 2 users: Timon & Bob

Timon logs in, Timon gets redirected to the page Timon.aspx

Bob logs in, Bob gets redirected to the page Bob.aspx

My loginform ID is called Login1, and its on the Default.aspx page, since I want users to login before viewing any content.

At the moment, I just login and it works (if I type wrong info it gives error etc), but when I login I just get redirected to Default.aspx again.

The code in my Default.aspx.cs at the moment is:

protected void Login1_LoggedIn(object sender, EventArgs e)
    if (Roles.IsUserInRole("Bob"))
    else if (Roles.IsUserInRole("Timon"))
