I created HttpHandler class in ASP.NET and configured a website to handle any request with the *.test path.
public class GameHandler : IHttpHandler, IRequiresSessionState
{
public bool IsReusable
{

return false;

I suspect the problem is that ASP.NET doesn't know these requests sent from javascript belong to the same session and that's why the Session values are lost.
I have a ASP.NET website which uses forms authentication. The timeout is twenty minutes.
I have noticed that if a user half completes a form, and is then timed out, they are redirected to the login page, fill it in, and are redirected back to the form but with EMPTY controls.
I had prevously assumed that ASP.NET would use some skulduggery to repopulate the form controls when this happens.
I have this code in the end of link button click:
Response.ContentType = "application/zip";
Response.AppendHeader("content-disposition", "attachment; filename=download.zip");
Response.TransmitFile(Server.MapPath("download.zip"));
Response.End();
Response.Flush();
to download a zip file from an aspx page.In the previous page i set a session variable, after going to this download page and download the file, then press back i find the session=null "this happen after downloading more than 1 time", and the application_end in global.ascx called. Do you know why this may happen??Note: this is happening on all browsers, on IIS7 both local and on my server.
I am creating a presentation on basis of some selected values and maitaning the selected values in a session variable named Session("userPref") in collection form.
Now I am opening a TablePreview.aspx page by javascript window.open() function.
On Page_Load of TablePreview.aspx I am reading some values of Session("userPref") and doing some operatons.
For saving the presentation I have created a page wizardsave.aspx.
Now I am opening the wizardsave.aspx from TablePreview.aspx by window.open() function for saving presentation, but on Page_Load of wizardsave.aspx. I found that some value from collection stored in Session("userPref") have lost.
An ASP.NET application (actually with Silverlight but it doesn't matter) is hosted in Outlook as folder home page. In this application there's a link to open popup window, which opens a separate IE window, not in Outlook.
The problem is that in this case it seems that ASP.NET session is lost. A call to ASP.NET service has nothing in Session and Session._id is different. I suspect that Outlook has different cookies than IE.
How do I preserve session when opening IE popup from Outlook? Maybe pass session id via URL somehow, or configure this in web.config?
I have a web form with a whole bunch of drop down lists (mainly) that works perfectly well and has been for some time. However, we've found a scenario that seems to corrupt the viewstate of this form in someway, or cause it to lose it's viewstate. The problem occurs when the user has this form displayed, then clicks on a link that opens up another window. A few more steps to open up a second and third window, followed by a write to the database. Then the user closes these windows down, leaving this original window open. At this point, the user selects something from one of the dropdowns. And the app crashes because the dropdowns have lost all of their values (and so a bit of code that is trying to work with one of the ddl's selectedvalues fails).
When the user selects this dropdown, the page_init event fires, followed by the page_load with postback = true. The dropdowns themselves are defined in the aspx page markup, but the values of them are generated and added in page_load (where postback = false). I've relocated the code to populate these controls to the page_init code and now the app doesn't fall over, because the values are re-populated. However, all of the selectedindexes are being reset, so the original values are lost and the screen redraws after this postback with all of the dropdowns reset.
I am using c# and jQuery.
I have below code where I am setting the Session Variable using C# code.
if (!string.IsNullOrEmpty(results))
{
string[] array = results.Split(',');
string firstName = array[0];
string lastName = array[1];
string activeCardNo = array[2];
string memberShipTier = array[3];
string accessToken = array[4];
Session["skyFirstName"] = firstName.ToString();
Session["skyLastName"] = lastName.ToString();
Session["skyActiveCardNo"] = activeCardNo.ToString();
Session["skyMemberShipTier"] = memberShipTier.ToString();
Session["boolSignOn"] = "true";
Response.Redirect(fromPage);
Response.End();
}
Now I want to read these values (Session["skyFirstName"]) using jQuery so that I can set in my elements.
I need to make my asp.net session cookie as secure but whenever i check user authentication and after that i am trying to set cookie to true then my session lost my user information and so it always redirect login page. I am settings user to HttpContext.Current.Session["user"] and check every time, is user is valid and if valid then move ahead. but before that i make my asp.net session cookie as true.
[Code]....
but after that i observe that somehow "Session_Start" event gets called.
concatnate two session values. I need to concatnate
Session["probmgremail"].ToString();and Session["TextBox2"].ToString();
The output should be a combination of two values seperated by a semicolon(;).
The session values are email address.
We have many instances in our application where we would like to be able to access things like the currently logged in user id in our business domain and data access layer. On log we push this information to the session, so all of our front end code has access to it fairly easily of course. However, we are having huge issues getting at the data in lower layers of our application. We just can't seem to find a way to store a value in the business domain that has global scope just for the user (static classes and properties are of course shared by the application domain, which means all users in the session share just one copy of the object). We have considered passing in the session to our business classes, but then our domain is very tightly coupled to our web application. We want to keep the prospect of a winforms version of the application possible going forward.

User hits webapp and is shown Introduction.aspx
User continues using webapp for a few minutes (ASP.NET_SessionId: ublbhu45ji31e055ywqu0555)
User falls idle (doesn't perform any postbacks) for a few minutes
User performs postback
User is shown Introduction.aspx
Second inspection of user's ASP.NET_SessionId cookie still shows ublbhu45ji31e055ywqu0555
Why is the user shown Introduction.apsx the second time inside the same ASP.NET Session? I'm familiar w/ the risk in setting session variables just before a redirect in the same postback, but that doesn't apply here, right?

Now in login page after firsttime login i set some session data... like
protected void Login_LoggedIn(object sender, EventArgs e)
{
//.....
Session["EMPLOYEELOGGEDIN"] = "Y";
//.....
}
Now say i close the browser... and next time when i open the site it takes me directly to the default page [Login_LoggedIn is not called accordingly]... because i'm already logged in for 30 mins acc. to configuration. but as my session id gets changed i can't access Session["EMPLOYEELOGGEDIN"] from any page in this time. It always returns null. But how do i get back the previous session for that person?
I'm evaluating using Ajax in a new project and so I've developed a simple web page to test a few things, however even the simplest task seems to cause my session to be cleared. I am using VS2008 with .Net 3.5 SP1 and the page is in my existing solution which has several custom handlers and modules in the web.config. Below is the code I'm using, it's a simple test which puts a variable into the session then on the buttons postback tries to get the same variable, however it always fails as the session is blank.
The Default.aspx code snippet
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" /> [code]....
I have an asp.net login page, which when initialized sets some session variables. When the user clicks login, an AJAX request is made which validates the user and sets additional session variables and returns a result to the client. The client is then redirected based on the login result. In the redirected page, I can access the session variables set when the login page was initialized (i.e. before the login) but none are present for those set during the login validation (part of an ajax call).
is this expected behaviour? Why would an ajax call generate a new session and thus cause the data to be lost?
I am setting a Session variable in an HttpHandler, and then getting its value in the Page_load event of an ASPX page. I'm setting it using
public void ProcessRequest(HttpContext context)
{
HttpPostedFile file = context.Request.Files["Filedata"];
context.Session["WorkingImage"] = file.FileName;
}
(And before someone suggests that I check the validity of file.FileName, this same problem occurs if I hard-code a test string in there.) It's working just fine in IE, but in Firefox the Session Variable is not found, getting the "Object reference not set to an instance of an object" error in the following code:
protected void Page_Load(object sender, EventArgs e)
{
string loc = Session["WorkingImage"].ToString();
}
Has anyone encountered this problem - and hopefully come up with a means for passing the session variable?
I've got an ASP.NET MVC app running under IIS7. It's using the default in-proc session management, which, according to all that I read, should lose the users' session after an app pool recycle.It doesn't seem to be losing it though. Even an IIS reset doesn't lose the session.Has something changed in IIS7 that keeps the session alive?
View 1 RepliesI am developing an application using Visual Studio 2010 and SQLServer 2008. My application has two pages and the first page contains a GridView with all the records "User Administration" and when user click on any Username (template field ->linkbutton) I read the USERID like this.
Session["UserID"] = e.commandArgument;
Response.Redirect("UserOperations.aspx");
which takes it to the Data Entry page where user updates the information and save the data.
The problem i am facing is that when I hit the browser REFRESH button couple of times the session variables looses the value which is trouble for me as I am using Session Variables for different purposes.
