C# - Best Approach To Handle Session Timeouts?
Jul 22, 2010
There are various ways to handle session timeouts, like "meta refreshes" javascript on load functions etc.
I would like something neat like: 5 minutes before timeout, warn the user...
I am also contemplating keeping the session open for as long as the browser is open(still need to figure out how to do it though... probably some iframe with refreshing).
How do you handle session timeouts, and what direction do you think i should go in?

Can I still use Session_OnEnd to trap a session timeout? Is there a better way to trap a session timeout? I want to take the user to a page that tells them the session timed out, and give them an opportunity to re-enter the application in a new session if they wish. How can I accomplish this? Is there still a global.asax file in the .NET 4.0 world?

My web.config file contains:
<system.web>
<membership defaultProvider="AccessMembershipProvider"
userIsOnlineTimeWindow="30">
<providers><clear/>
<add
name="AccessMembershipProvider"
type="Samples.AccessProviders.AccessMembershipProvider, SampleAccessProviders" .... >
</providers>
<membership>
I expected this would set 30 minutes as timeout for inactive sessions, but they seem to be timing out much sooner.
Is there some other way to specify time for session timeout ?
I know I am using an unsupported AccessMembershipProvider which I was forced to do because my host service does not support SQL Server Database (so I am using an Access Database).
However, this AccessDB provider seems to work fine in all other respects. I'm suspecting that the early timeout is because of some other obscure setting.

I are building a web application which will be deployed to Windows Azure. I want user to set session timeout value which will be stored in Database. Currently I am aware of Web.Config method to set session timeout. i.e.
<sessionState
mode ="InProc"
timeout ="60"></sessionState>
Is there any method to set session timeout value according to User's Preference?

I am using nhibernate in an open session per view approach where the session opens before the action method and closes right after. Using an AsyncController makes this model break because the controller performs data operations even when it has returned from the original XXXAsync method but it finds a null session while the HttpContext.Current is null as well. Is there any way to fix this issue?

In the project I'm working on I have got a list List<Item> with objects that Is saved in a session. Session.Add("SessionName", List);
In the Controller I build a viewModel with the data from this session
[Code]....
and in my View I loop trough the list of Items and make a form for all of them to be able to remove the item.
[Code]....
When the post from the submit button is handeld the item is removed from the array and post back exactly the same viewModel (with 1 item less in the itemList).
return View("view.ascx", viewModel);
When the post is handled and the view has reloaded the value's of the html.Hidden and Html.Textbox are the value's of the removed item. The value of the html.Encode is the correct value. When i reload the page the correct values are in the fields. Both times i build the viewModel the exact same way.

I'm making an ajax call using jquery to an asp.net mvc controller action:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult GetWeek(string startDay) {
var daysOfWeek = CompanyUtility.GetWeek(User.Company.Id, startDay);
return Json(daysOfWeek);
}
When session times out, this call will fail, as the User object is stored in session. I created a custom authorize attribute in order to check if session was lost and redirect to the login page.

I have a simple ASP.NET 4 site. I am using Forms Authentication. I have Session timeout set to 20 minutes. Also when the user authenticates I set the AuthenticationTicket to expire in 20 minutes. So normally everything works fine. If there is more than 20 minutes of inactivity and the user requests a page on the site they are redirected back to the Login page as I would expect.
However, let's say that the user is on a page that contains a form. Then they wait 25 minutes. Then they go to submit the form. Instead of being redirected back to the Login page, the site attempts the postback and I immediately get errors because there is code in the postback that attempts to get information out of Session.
It seems like ASP.NET does not redirect back to Login on postback if the AuthenticationTicket and Session has expired. How can I handle this? I hope I don't have to write special code on each page.
ADDED: web.config code
<location path="ForgotLogin.aspx">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>
<system.web>
<authentication mode="Forms">
<forms loginUrl="~/Login.aspx"></forms>
</authentication>
<authorization>
<deny users="?" />
</authorization>
</system.web>

I am having an aspx page page1.aspx with a button button1. On click of button1, a modal window popup is displaying using jquery.
The modal popup is displaying another page page2.aspx . I have appended the following line in the load event of all aspx pages to handle the session expiration.So that on expiration of session, it will automaticaly redirect to sessionexpired.aspx page.
Response.AppendHeader(
"Refresh",
Convert.ToString((Session.Timeout * 60) + 10) +
";URL=SessionExpired.aspx");

I have a web service that sends up to 5000 emails to our customers.
It is called asynchronously from a web application and then chuggs away sending the emails. Generally it works okay. Yesterday, it kept stopping - sometimes after sending a small number (33 first time) and then it might send another couple of hundred - then 50 or so etc. This went on all day as I kept manually calling the web service.
The data (subject, body, fromaddress, replytoaddress etc) is all kept in the database - as are the recipients.
Here's the code that gets the data from the database.
// Create Instance of Connection and Command Object
SqlConnection myConnection = new SqlConnection(ConnectionString);
SqlCommand myCommand = new SqlCommand("CPEmailsToSend_List", myConnection);
// Mark the Command as a SPROC
myCommand.CommandType = CommandType.StoredProcedure;
myCommand.CommandTimeout = 1000;
[Code]....
So I have a dataset containing 3 sets of data - the subject, body etc., a list of attachments and a list of recipients. I then use the .net smtpClient like this:
Code:
//about to start sending emails - update the MessageSendStatus to inprogress
myCommand.CommandText = "CPEmailSendStatus_Update";
myCommand.Parameters.Clear();
myCommand.Parameters.Add("@CPEmailID", SqlDbType.Int).Value = CPEmailID;
myCommand.Parameters.Add("@SendStatus", SqlDbType.TinyInt).Value = 1;
[Code] ....
When the web service stopped (it kept stopping yesterday) - no errors were raised. I have a function on the page that checks the email address is valid before I try to send the email as I know the smtpClient does not like invalid email addresses. Normally, invalid email addresses are trapped and the loop continues and sends the next one etc. But, yesterday, it just stopped sending. No error messages - nothing.
So, I began to wonder if the Command object is timing out. With a lot of email addresses to send to (up to 5000) and half a dozen attachments - the web service can take a long time (hours) to send all the emails. So, is the fact that I am reusing the command object over and over again for different stored procedures the issue? (I do this a lot and have never had a problem before - I read somewhere that the CommandTimeout only counts the time network access is used).
I've been sending test emails all morning (but I can only send small batches as I have a limited number of email addresses I can send test emails to) and they have all worked okay ... but, yesterday, trying to send about 5000 emails took about 30 attempts.

I have a webservice, that when called, calls many other web services based on the information that was sent. I have always left the timeout as the default, or a better way to describe it, I have never changed anything.
How (and where) do I change the timeouts for each service individually. Since I have quite a few now, I want the original transaction to never take more than 30 seconds. That said. I want to go in and change the timeouts for the services I have to ping in that 30 seconds to be 5 to 10 seconds based on which one.

I'm using visual studio 2008 and sql server 2005 and everything is working just fine under normal use. However if a user is on a page for a while several minutes with no activity then clicks a button on occassion the site throws the following exception ...
Procedure or Function "sp_name" parameter '@SomeParameterName', which was not supplied
I'm also encountering this error in Visual Studio while debugging the application, in otherwords run the site from visual studio then make some change to the html in VS save the changes and refresh the page.
The error is not consistent nor is the time the page has to stay idle in order for it to occur....
The current sql command object timeout is 30 secs and the website timeout is 30 minutes.

I've converted an ASP.Net website over to an Azure version and I've got it up and running. However the vast majority of the time I experience timeouts when I'm trying to debug the application.This seems to happen on any page at any time. I start debugging from VS2010 and sometimes the home page will come up sometimes it hangs. When it does come up if I select an item from a drop down list sometimes it works somtimes it times out. I have breakpoints set and they don't even fire I just eventually get the time out.
If I hit refresh that sometimes seems to fix it but it eventually starts happening again. This is making the completion of the conversion VERY difficult and I'm starting to creep up to a deadline.Does anyone have any idea what might be happening? If there is a better location I can post this question to would someone be kind enough to point me in the right direction?Thanks in advance for any help and in addition my email is
mgorgone@pictureu.com as our Windows Live account email is diff.

On an administrative page with a long running process we're setting the following:
protected void Page_Load(object sender, EventArgs e)
{
this.Server.ScriptTimeout = 300;
//other code
}
Is this enough that should prevent that page from timing out as it does what it needs to? I have no control over the process and how long it runs but we've found that 5 minutes is more than enough time, yet we're still getting intermittent errors of:
System.Web.HttpException: Request timed out.
We've tried upping the value to 600 with really no difference and in any testing we've done we can never get the actual process to run for that long. Is there elsewhere that we need to be setting timeout values that won't affect the entire application and only the specific page we need the longer timeout value on?

I have code in an ASP.NET form that needs to, depending on user entry create messages in the database. We are speaking of potentially thousands of db entries. How do I protect against deadlocks, I mean apart from using Transactions and setting IsolationLevel to Serializable, as well as using WITH(NOLOCK) statement on my select statements since I don't mind a dirty read.

I have an asp.net page that will be doing some processing that may take a very long time to complete. I cannot just set the page timeout value since this is going to be in a hosted environment and the timeout values that I set in my web.config are overridden by the server host. What I'm doing is taking a file from a FileUpload control and doing some web requests to a 3rd party service for each line in the file, all of which may take a very long time to process a large file. I'm talking on the order of, say, 30 minutes, and there's just no way to optimize this any further to cut down on the processing time. Is it possible to even do such a lengthy page request in asp.net? Can someone give me a pointer in the right direction here to make this happen? Is my only hope to create an async page? It seems that doing an async page is the way to go if I have a potential for a lot of lengthy requests, but really this massive of a request is going to happen VERY rarely so this is not an issue of running out of thread pool since most of the time this particular request will be completed relatively quickly, but on occasion it may receive a very large file it will need to process and will take a very long time. So what is the best way to handle that case?I'd also like to update the client with the processing status as the processing is going on. I'm familiar with doing client ajax calls via jQuery to a page webmethod so if there is some clean way to update the client as this long processing

What is the best approach to one to many relationships?
This is my scenario:
I have a simple one to many relation:
Customer
CustomerID
Name
tel
CustomerNotes
Id
Note
customerID
I want to have a DETAIL view of customers and CREATE view for CustomerNotes all in the same page.
I create CustomerController and the different views and its respective actions for edit, create, delete, etc.
I also create a CustomerNotesController and the views and actions like before, but I made the views PARTIALS
I put a RENDERPARTIAL for the CustomerNotes create view in the Details view from Customer.
When I run the app, the page is render as expected: It shows the detail info of the customer and bellow the create form for the notes. However, when I click SAVE, nothing happens. I put a breakpoint in the notes controller and never get hit.
I also try with RenderAction and don't work at all.
