View 6 RepliesI'm using the code below in the we.config file.
<sessionState mode="InProc" cookieless="false" timeout="30"/>
There is no issue with the session expiration locally, but the same web application logouts frequently when I uploaded it to the webserver. The session no longer keep it's state for 30 minutes when the application left idle for some time.
when i run my web application in my system the session not expired during access of the pages, but when i launch application in the remote server the session expired during access of the pages
i specifiy the session time out in web.config as follows
<sessionState mode="InProc" cookieless="false" timeout="30" />
But i don't know what the problem is
I receive the error message "Error: Your session has expired. Please refresh your browser." When I export a table in ASP to Excel. I know for a fact that the correct data to export exists. Everything works fine except for this error message. I don't see how the session on a browser could run out in a matter of the one second it takes for the Excel file to pop up
View 2 RepliesMany web applications use sessions to check the logged in status of the users. Is there a better approach to check the logged in status instead of using session state?
I'm looking at a pure ReSTful approach where is no session state at all. This may make more sense in an mvc application rather than an asp.net application.
What is the function used to check a session exists or not?

View 6 RepliesI am writing a chat application, in which a chat starts in a chat room. Now, i want this room active only for a certain amount of time and not more. i.e 1 hour etc. So, to check the time constantly what and how should i write something in the background, so that when the time is over, the sessions of all the users logged in at that chat room get destroyed. And the users are again redirected to the login page. e.g The chat has been setup from 3 to 4 pm. At 3.55 everybody should be given a popup that the chat will end in 5 mins. And at 4 everybodys session should be destroyed and they should be redirected to the login page.

As we know that closing a browser will delete cookie if the cookie does not set an expired date. However, I want to set an expired date to all of my cookies and also delete them when browser closed.
View 2 RepliesI read the solutioin for this error, at the following link :http://forums.asp.net/p/1046935/1576341.aspxbut I am still not clear what exactly causes the error. I have two doubts :1. Can anyone please elaborate a bit on this issue, with any example ????2. Is there any drawback of this approach ?
View 4 RepliesI am using the following code to ensure that the web pages in my website are not cached by the browser:
this.Response.Expires = 0;
this.Response.AppendHeader("Pragma", "no-cache");
this.Response.Cache.SetNoStore();
This is working fine & the browser displays a page with the message, "Warning. This page has expired....". Is there any way I can display a custom page instead of the default page shown by the browser?
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?
