I set a session at login and I lose it after about 3 button clicks. I don't know why. The following is what I have in my webconfig:
<sessionState
timeout="52000"></sessionState>.
My web application was in .NET framework 1.1 initially. It has a few ASP server grids and some third party controls (Infragistics). I had it migrated to .NET framework 3.0.
Now I've added a few ASP server grids('GridView'). The thing is when the session('InProc') ends after 20 mins, the rows of the newly added grids disappear. However, this is not happening with the grids that were present already pre-migration. I am not using any session variables to initialise or bind the new grids.
This is happening only if the controls are added in the web forms that were involved in the framework migration process. If the control is added in the new web form, then this issue's not occuring.
Also I am not allowed to change the session state to any other. It has to remain 'InProc'. Continuing the session indefinitely is also not an option.
I have written custom code for login and logout...When use clicks on logout button the current session is closed and user is redirected to a login.aspx page...The problem is that when a user click a back button on internet explorer it the previous page he was navigating is shown to him...(altough he cant perform any operation as session is null and their is condition in page load that if session is null user should be redirected to login page)May i have to clear cache of client ??
View 3 Repliesknow much about session management. I used only sessions variables in SignupForm, Forget Password. I dnt know how to code or login and logout via session. What is inproc and outproc.
View 1 Repliesi have a query regarding Sessions in ASP.Net. The scenario is:
My web application is for Mobile Phone. The default session timeout is 20 minutes. There is an option of "Remember Me", on checking which, the application also stores the permanent cookie whenever user signs in.
Now the requirement is that if the user has logged in with the "Remember Me" option checked and the session has expired due to inactivity for more than 20 minutes and then he tries to do some activity, the user should not be redirected to the login page.
In the sense, the process of authentication should be skipped. It should be taken care of by the application and the user should directly continue with his work. But also if the user signs out, then he should be redirected to the login page for authentication.
Now, the scenarios I can think of are:
1). A check can be made that if user has checked "Remember Me" the authentication process should be skipped so whenever session expires and user do some activity, the authentication part can be done automatically and he will continue with his work. But in that case, once a user has signed in with "Remember Me" option checked, he would never be able to Sign-out unless he deletes his cookies.
2). Refresh(reset) session as soon as it comes to expire. But then its against the requirement.
3). Use of some kind of flag which can be set to some value that states that there was a session time-out. This is the closest option according to me if I get to know how can this flag be used in the application. As if I make it as an Application Variable then it will change with every user's activity and be same for all users. Same is the case with static variable.Is there any other option available?
i create a web site using frame and child when session i s out i require Login page open in browser not opend in frmaehow to set Session out open login page
View 1 RepliesBy default when the Session ends then the End-User should be directs to the login page and logs in again. Is there any way to open the login page in a new page rather than opening it in the same page(upon Session time out)?

View 4 Repliesi have 2 page,
1.login.aspx --- 2.welcome.aspx
in my login.aspx im storing username into sesssion as below:
Session["usernm"] = txtUsername.Text;
in my welcome.aspx page
in page_load event
if (Session["usernm"]==null)
{
Response.Redirect("Login.aspx");
}
here if i manulally paste the url ( http://localhost:4125/Loginado/welcome.aspx) it should go to login.aspx for user credentials
but its going directly to welcome.aspx page.
I have an issue of keeping the authentication and session state on a downloaded page, on the same website.
I have 2 pages, page 1 will download page 2, using the following code:
Page 1 code:
System.Net.WebClient webClient = new System.Net.WebClient();
byte[] buffer = webClient.DownloadData("http://www.mywebsite.co.uk/page2.aspx");
return Encoding.UTF8.GetString(buffer);
but the authentication is lost, so i needed to re-login in page 2 by writing auto login code myself.
But then the session is lost, so the session variables set in page 1 cannot be share to page 2, and vice versa.
I have one website in which there is one page along with one ascx as registered into it. In the ascx where user can add some order details and click on "Make Payment" button, then there are following 2 cases...Case I: If user was not logged in, then a modal popup will open which has login ascx with 2 buttons Register & Login. In this case user either Login or Register and continue with "Make Payment".

View 11 RepliesI am working on a site in which some pages are to be run on secured server(ie https) & some on non-secured(ie http) eg Login, User Information, etc. will be run under https & View cart, etc. are to be run on http. Now, when user chooses some products in his cart, he is prompted to enter login details. After he fills in his login detail(ie in https), he is redirected to Checkout. But here the Session doesn't picks the value and it shows Session[UserID] value null. So, rather then redirecting to Checkout it shows MyAccount page. Does anyone know how to pass Session Value from https to http.

Customer were getting "View State Validation Error" due to worker process recycling at our production webserver and to fix that i applied machinekey and then move my Session state Mode from In Proc to State Server to retain session data and not kick out the customer to relogin. I had serialization issue with one object which has to be stored in session but when i moved it out of session i could able to resolve the issue.
But doing all these i was partly successfull in keeping the user in their session when Worker Process recycle event occurs.I was able to refresh the page or make a post back by clicking the refresh button and also able to retain the session values. But the Problem occurs when sending asynchronous request to server which we do periodically every 15 minutes from the moment the user logs in.The web page doesnot update data on website when sending asynchronous request.By Debugging I found at this particular code point it fails to make a postback which is required.
<%=GetHintFromServer%> (When there is no Worker Process recycle i t gets replaced by
WebForm_DoCallback('__Page',message,ShowHint,null,null,false) on postback) Everything works fine when there is no Worker Process Recyling but when it happens looks like sending request asynchronously using javascript fails .Remember When I make a post back by manually clicking submit button everything works fine.
SendRequest(Asynchronous)
function SendRequest(msg, isBusy, chartMsg, vesselMsg)
{
try
{
//confirm("msg"+msg+"isBusy"+isBusy+"chartMsg"+chartMsg+"VesselMsg"+vesselMsg);
_busy = isBusy;
if(chartMsg != null)
{
//confirm("chartMsg"+chartMsg);
_element.SetMessage(true, chartMsg);
}
if(vesselMsg != null)
{
confirm("chartMsg"+vesselMsg);
_element.ShowVesselLoading(true, vesselMsg);
}
_stuckWatchdog = setTimeout( "ClearPendingRequest();", 60000);
var message = msg;
var context = '';
<%=GetHintFromServer%>
}
catch(e)
{
alert( "Exception error on SendRequest(): " + e);
}
}
I am new to .net 4.0 and am using EF Model and SessionState Mode=SqlServer and I am getting this error below:
Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.
I checked the stack trace and its complaining about
[assembly: global::System.Data.Objects.DataClasses.EdmSchemaAttribute()]
[assembly: global::System.Data.Objects.DataClasses.EdmRelationshipAttribute("PoplarGroveModel", "tblMenuRole", "tblMenu", global::System.Data.Metadata.Edm.RelationshipMultiplicity.Many, typeof(PoplarGroveDataModel.Menu), "tblRole",
[Code].....
I marked it as serializable but then it complains about System.Data.Objects.ObjectContext is not marked as serializable and hence throws the same error.
Our ASP.NET App uses ASP State Session Management and has been rebuilt about 2 years ago [With .NET Framework 2.0]. We are currently in .NET framework 3.5 and have moved to SQL Server 2008 - but continue to use the same ASPState database. The State database has been upgraded to SQL Server 2008. Since then we have are seeing timouts/locks on ASPStateTempSessions table. I am wondering if we have to rebuild this database from scratch with some newer scripts?
View 2 RepliesI'm using the following line of code to display the number of users currently logged on:
lblNoOfUsers.Text = Membership.GetNumberOfUsersOnline().ToString()
I'm still debugging my application so it's on the local server. As I debug and stop then debug again, eventually lblNoOfUsers.text turns to "0" instead of "1", even as I'm navigating my application. It only turns to "1" again if I log out and sign back in. It's almost as though Membership.GetNumberOfUsersOnline my login are referencing two different session states. How is this possible? Does asp.net create a new session state cookie each time I start debugging?
I am trying to set a session variable in the global.asax file and keep running into the problem that the Session is null.
I am running my application in VS2008 and using asp.net 3.51.
Here is my code:
1. In my web.config file I have enabled the session state and added the following line;
<sessionState
cookieless="false"
mode="InProc"
timeout="60"
></sessionState>
2. In the Session_Start procedure in the Global.asax file I set the session variable to a default value.
[Code]....
My problem seems to be that when the Application_Error procedure is executed the session state is lost.
Does anyone know why the session state isn't available in the Global.asax file.
All we have a global ships position tracking website which runs smoothly until IIS application pool recycles.When there is workerprocess recycling looks like session state expires as a result i loose all session data and when customer clicks refresh button he is redirected to login page.
In web.config Session state mode is set to InProc so i changed it to State Server but to my luck i have MAP object which is not serialiazable which is causing the maps from not appearing on the website.I tried adding serializable attribute to the object class but still not succesfull.Our website is accessed by our customers whose count is more than 1000.
Changing the session state mode from InProc to StateServer can really slow down the response time so
Is it good to go further fix the serailizable issues and move to state server?.
Is there any way I can retain my session data when application pool recyles?..
Stopping Application pool from recycling may not be a good idea considering health factor of web server.
I have a clear button and a textbox in an aspx page. I set the session variable in this page as
String str = Textbox1.Text;
Session["TypeIds"] = str;
and I clear the sessions in a clear button event as
Session["TypeIds"]=null;.
Then when the user types some value in the textbox ,on Response.Redirect on another aspx page, the session variable returns null values.It does not retain its session state. The session state has to be maintained in the next page. Is it because this clear button event and setting explicitly to null creates this problem?
