Weird problem with session cookie

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :ASP.Net
 

Hi all,

I'm having a weird problem with my web application, and I can't find the solution to it.

I'm using a Java applet to read some data from an electronic ID. This applet posts its captured data to a HttpHandler class and stores the data back in some session variables. It all works smoothly, unless in some cases.

Every time a do a new publish to the webserver or the website isn't touched for some time. There is a problem with the session.

The applet can't find a session cookie, and so it crashes.

I did some tests and indeed, the cookie ("ASP.NET_SessionId") does not exists. But it seems that other session variables (user login, etc) are working fine.

To make sure that the cookie for the session ID is readable from the applet I do the following in the global.asax:

    Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
        ' Code that runs when a new session is started
        Dim isSessionFound As Boolean = False
        If Response.Cookies.Count > 0 Then
            For Each s As String In Response.Cookies.AllKeys
                If s = "ASP.NET_SessionId" Then
                    Response.Cookies("ASP.NET_SessionId").HttpOnly = False
                    isSessionFound = True 'just for test
                End If
            Next
        End If
   End Sub

SQL Server Session state problem.

  

Hi to all,


I have some things that I want to know. I am right now using a free asp.net webhosting ("somee.com"). The problem is that when I am visiting a page, there's a tendency that values stored in my session variables are lost. Therefore, it causes an error when the requested page is loaded.

1. I am thinking of using sessionState mode="SqlServer". Will it solve my problem?

Actualy Im working on it but Im having problems when connecting to the sql database.

2.  Is that a problem in the webhost?

3. Do free webhosting sites provide allow session state in the sql server?. Because ive tried it locally into my computer and error say's i should intall the ASP.NET Session State SQL Server version 2.0 or above.

Problem with Session and PageMethod

Session State Problem

  

Hi,

 

I just for the first time into a session state problem. So I am hoping someone

here has the answer.

 

I have written an ASP.Net website and tried to implement the common poor mans online user count.
The problem I am having is the following.

On App_Start I create a variable and assign it the value of 0;

Then increase the number on session_start and decrement on session_end.

On my local IIS it works perfectly from IE8 and Opera. The value increments correctly.
As soon as I upload to my live server. The value increments on every link I click and every page refresh when I test with IE8.
This does not happen when testing with Opera.

Could someone please shed some light on the subject.

 

Thanks

i have an application that uses sessions.

i have set at the web.config: 

<forms loginUrl="Default.aspx" protection="All" timeout="30" name=".ASPXFAUTH" path="/" requireSSL="false" slidingExpiration="true" defaultUrl="Default.aspx" cookieless="UseCookies" enableCrossAppRedirects="true"/>

and at the global.asax.vb

Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
        Session.Timeout = 30

end Sub

and at default.aspx.vb

Protected Sub LoginButton_Click(ByVal sender As Object, ByVal e As EventArgs)

Weird problem in Detailsview - Dropdownlist in

  

Hi,

I'm new in this forum and I really hope you'll be able to help me.

I converted a field in the detailsview into a template field and put a dropdownlist in the <InsertItemTemplate> and it worked great. This is the code I put:

<InsertItemTemplate><asp:DropDownList runat="server" DataSourceID="sdsGenresPossible" DataTextField="Genre"  DataValueField="Index" SelectedValue='<%# Bind("Genre") %>' ></asp:DropDownList></InsertItemTemplate>


Now, I tried to do the same thing for the <EditItemTemplate> . This is the code I put there:

<EditItemTemplate><asp:DropDownList runat="server" DataSourceID="sdsGenresPossible" DataTextField="Genre" DataValueField="Index" SelectedValue='<%# Bind("Genre") %>' ></asp:DropDownList></EditItemTemplate>  

When I change the DV properties I do see that a dropdownlist was  added but when I run the program and click on "Edit" in the DV nothing happens (however when I click on "Insert" it works fine).

This is the Select command for the data source I used:

<asp:SqlDataSource runat="server"
          

weird problem of using multithread to querying sql server

  
Hi,   I'm working on a project which needs query the sql server many times to pull the statistics info. the whole process is very slow. so, I'm trying to use the multithread to do the work. However, I noticed one weird thing:   In the program, I need pull, say 10000 documents from the sql to local PC, then can do some analysis. Each document size is different. If I used 1 thread, say for document A whose size is 5MB, it will take about 20 seconds for the SELECT query returns the result. Now, if I used 10 threads, I found that it will take much longer time for SQL to return the SELECT query for document A, say maybe 90 seconds. I got the run time for the SELECT from the sql profiler.   Overall, the performance of multithread is very similar to single thread even I use 50 threads. I used the same code for another project, the only difference is that that project scrapes data from website and this project gets data from sql. The other project works very well when using multithread. so, I'm kind of believe that the multithread part code works fine.    Could this because some settings on sql server? some bandwidth limitation? any clues?   any help/suggestion will be appreciated.   thanks reader      

Best way to connect a Cookie to a session?

  
I usually like to do it the hard way, just to get a feel of what you can do! In ASP.net there is probably a really simple way Forms authentication etc. but this is what I have. I know from previous experience that you should never save a Cookie that contains a password, so how to connect a session to a cookie when the user accesses the website, with saved cookies information. I though about using a Guid, in the cookie, and then check the database to see if that guid is available, but this could be a sort of password like effect. Here is my code. Private Sub Login1_LoggingIn(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.LoginCancelEventArgs) Handles Login1.LoggingIn Dim mDbase As New SQL("<Server>", "<Database>", "", "", True) mDbase.Open() Dim mUserItem As UserItem = mDbase.Record.Item("SELECT TOP 1 Username, First, Surname, AccessLevel, LastVisited FROM TBLUsers WHERE Username='" & Me.Login1.UserName & "' AND Password='" & Me.Login1.Password & "'", GetType(UserItem)) If mUserItem IsNot Nothing Then If Me.Login1.RememberMeSet = True Then 'Dim mGuid As Guid = System.Guid.NewGuid 'mGuid.ToString() 'Create cookie data End If If Session("User") Is Nothin

ASP.NET Cookie Problem : Credential Cookie

  
Hello everybody. I am trying to create a cookie for storing Username and Password.This is so far I am :protected void Page_Load (object sender , EventArgs e) { if (!IsPostBack) { HttpCookie cookie = Request.Cookies["CredentialCookie"]; if (cookie != null) { string username = cookie.Values["Username"].ToString(); string password = cookie.Values["Password"].ToString(); TextBox Username = (TextBox) MasterLoginView.FindControl("UsernameTextBox"); TextBox Password = (TextBox) MasterLoginView.FindControl("PasswordTextBox"); CheckBox RememberMe = (CheckBox) MasterLoginView.FindControl("RemMeCheckBox"); CheckBox RemMyCred = (CheckBox) MasterLoginView.FindControl("RemMyCredentialCheckBox"); if (username != null) { Username.Text = username; } if (password != null) { Password.Text = password; } RememberMe.Checked = true; RemMyCred.Checked = true; } } } protected void LoginButton_Click (object sender , EventArgs e) { TextBox Username = (TextBox) MasterLoginView.FindControl("UsernameTextBox"); TextBox Password = (TextBox) MasterLoginView.FindControl("PasswordTextBox"); CheckBox RememberMe = (CheckBox) MasterLoginView.FindControl("RemMeCheckBox"); Label ErrorMsg = (Label) MasterLoginView.FindControl("ErrorM

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?

Weird memory problem

  
Hi all.   I am quite new to c#, I have the following code segments and both of them cause the program to throw System.ComponentModel.Win32Exception indicating that memory is not enough. Both of the code segments is in a form.   while(true) { System.Drawing.Graphics g = this CreateGraphics(); System.Drawing.BufferedGraphicsContext c = System.Drawing.BufferedGraphicsManager.Current; System.Drawing.BufferedGraphics b = c.Allocate( g, new System.Drawing.Rectangle(0,0,3000, 3000) ); } while(true) { this.Controls.Clear(); this.Controls.Add( new Label() ); }   My question is shouldn't the resource created handled automatically by garbage collector ?   Thanks a lot.

Weird query plan problem where total is over 100%

  
Hi All, I am looking at the query plan for a stored procedure and I am seeing things like 1400% on the execution plan, the stored procedure I believe is called within a loop quite a lot of times, but I don’t quite understand why the percentages will be over 100 for one section of the execution plan. Any explanation for this ? Thanks in advance.
