Catch when user login cookie has expired. How to?

Posted By:      Posted Date: September 26, 2010    Points: 0   Category :ASP.Net


I have an ASP.NET MVC application that uses the Forms Authentication. I have the following configuration block inside the Web.Config:

<authentication mode="Forms">
  <forms loginUrl="~/Login/LogOn" name=".td_gsl_login_cookie" timeout="10" slidingExpiration="true" />

So if the user does not click any link for 10 minutes it will be disconnected and redirected to the LogOn action at the next click. This works very fine in my app.

Now what is really annoying is that I have some links in my app that open up a modal popup window (using jQuery UI) who retrieves their content dinamically using ajax requests and if the user click on one of these links after his login timeout has expired the result is that the login page is showed inside the popup dialog. The effect is really bad...

I understand that developing a script to check if the user is still connected would slide the cookie expiration.

Do you have any suggestion on how to address this behaviour?

thanks for helping

Forms based users being prompted for windows authentication login for My Sites photos in user lists

Here's an issue I didn't see coming for our forms based authentication users. 

We have a web application extended to an external url to handle forms based authentication for users outside of our domain. Our setup looks like this...

Internal Users/Windows Authentication - moss.domain.com
External Users/Forms Based - mossext.domain.com
My Site for Internal Users - mysites.domain.com

When our forms based users are accessing user lists, or discussion pages that display user pictures, they are getting a windows authentication login for our internal users (mysites.domain.com) who have populated their my site with personal photo.

How do we fix this? 

Issue with Remember Me on User Login control


Hi everyone,

     I hope you can help me, I tried Google, but none of the solutions worked. Using VB.net and Membership, I have a login control in my master page with a remember me check box. When I check this box and login, some pages indicate that I am not logged in. If I go to another page, it will then indicate that I am still logged in. I have isolated one page that always indicates I am not logged in the first time I visit it, but if log in a second time and then go to it, it will finally recognize me as a user that is properly logged in. 

Some pages that this occurs on is in the top level, some pages are in a sub folder.

My MasterPage has the following Form Code:

<body bgcolor="#E0ECF9" topmargin="0" leftmargin="0">

    <form id="form1" runat="server">

My Aspx file has a troubleshooting label, several Gridviews and several DetailViews:

    <asp:Label ID="lblErRep" runat="server" Text=""></asp:Label>

My aspx.vb file has 1 line of code (Protec

Login Failed for User "XXX" when login from a ETL machine for Sql Server 2005 SP2

Hi Guys, I have a straange issue with Login Failed errors coming intermittently probabaly twice in a week: I have a  production Database on Server A and we have Two ETL servers on Server B and Server C. Sometimes when the ETL's (SSIS) run from SERVER B I do get an error stating login failed for user "XXX" this user is a sql server user. And when I run the same package from Server C it does not give any error and runs smoothly. Both the packages uses the same configuration file to connect to the same database with the same user credentials. Also this error is not a frequent error but comes along once or twice in a weeK. Can anyone shed some light on this and let me know the root cause. Both servers have the same sql client version as well. All servers mentioned above are 64 bit windows 2003 servers. Raju
