State Management :: Session Timout And Refresh Metatag?
Feb 10, 2011
I'd like my page to refresh through MetaTag and redirect to SessionEnd.aspx, when the user Session expires. I use this code:
[Code]....
If SessionTimout = 1 minute, this code attaches Refresh Metatag, but it refreshes after 2 minutes, not 1 minute after the Session expires. If the user browse the page, the Session doesn't expires. The session should expires 1 minute after the user stop browsing the page.Is it possible to control the real session behaviour, not just to put static value, like 2 minutes or SessionTimout + custom minutes.Can I use something like:
I have an application containing many aspx-scripts.
How can I refresh the sessionvariables before timeout on the server independent of which script is loaded in the browser? (to prevent timeout when the browser is not used so the sessionvariables is refreshed)
When I used Coldfusion, I run the application in a frame and updated the session-variables by using a hidden-frame, but this techniqes dont work in aspx.
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
I have following code which end up with posting error randomly.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Page.IsPostBack Then Session("sendmsg") = Server.UrlEncode(System.DateTime.Now.ToString())
Is there a good way to keep the session after a user clicked reload/refresh? My boss wants this functionality, and I don't really/really don't want to use a query string...
I 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 ?
*1* report views -- 4 options -- NOT in updatepanel *2* pagination views -- 2 options -- IS in updatepanel
The situation goes as follows: Refresh WORKS in default setting but when I select *2* radio button options and refresh the page renders the state that the (1) was entered in.
I am using the session variable to hold the Pagination Viewing option but during page states, I've noticed that when a 2nd option is selected of *2* radio buttons (doesn't matter of 1st or 2nd option was initially selected) that during debugging mode the step over corrects the issue but not the right table viewing. Upon entering Page_Init selection selection index of radio button list returns to 1st option.
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.
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
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?
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?
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?
The fix for this error message is to run [Code]..... I have run that uptown, downtown and in my lady's chamber and it does no good, although it never complains. Are there any other possibilities?Details: IIS Server: v5.1 running on XP. SQLServer 2005 running on a different XP box.Microsoft .NET Framework Version:2.0.50727.3615; ASP.NET Version:2.0.50727.3618 There is an ASPState database on the server, containing only two tables: [Code].... and [Code]..... I did not use [Code].... when I ran [Code].... .
I am building a web app that is limited to one database, therefore I cannot use the ASP.NET config tool. As a quick means of getting this app online, I tried to use a simple session variable. The login page verifies the user's credentials, and if they pass, it sets the session variable to a certain value. All other pages check in the page_load event whether or not the session variable is equal to that value. The problem is that once being logged in for a short while and sending and recieving some data, the session variable resets, and I'm returned to the login page to repeat the process. Here's the basic code from my webforms:
[code]....
Is there some setting I need to change in the web.config file to adjust the cookie timeout or is that only for the config tool authentication methods?
I write a simple web site in asp.net. In one page i want to delete a folder of web root. When i delete it folder, the all session in project is changed to null. I write a post in this forum. Here is the adress of it post: ([URL]) Some pepole answer me to change the session state mode to StateServer. In default the session state mode is Inproc, and i changed the session state mode to stateServer.but when i changed the session to stateserver this error is appear in application eventlog after two day and my web site dont working in iis. This error is like this:

We have a web site that implements a custom SiteMapProvider using a User Control added in the master page. I need to be able to limit the sitemap nodes added depending on the logged in user, that is, certain users should not see certain sitemap nodes. Currently, the login processing code determines if users are in the certain category or role and then sets a value in session state, for example, Session["UserInRoleXXX"] = "Yes"; I tried changing the code in the user control to check the session state, but I got the following error: NullReferenceException ... Object reference not set to an instance of an object." Can session state be accessed in a user control?
I am getting this error "The session state information is invalid and might be corrupted " as i hve checked all my session variable initialized with some default value and the existing code works fine in version 1.1 but on conversion it is giving specified error. The error comes when i simply click on a link to redirect to some other page.
I created a form where I put some radio buttons. When User select one of them depending upon the option it will start his / her time counter. StartTime and EndTime and I am couting total time he/she takes. Till here it is OK. But what I want when user clicks on Logout, then he/she will logged out (Temporary). and after the some time when he / she will again login..... here, I want to set his / her EndTiming. I don't understand how to maintain this state?
I'm not sure if this is an error or is the right work mode for sql sessions.
I'm working now with Windows 2008 R2 Web Ed. and SQL Server 2008 Web Ed.
When I close my browse and open again a new browser window I need to login again in asp.net application and a new session is created in the sessions table in sql server.
It's this normal? I remember that with Windows 2003 and SQL 2005 this doesn't happend. When I closed my browser and open inmediately a new browser window my session was retained and I could continue working without relogin.
I have upgraded our system from .NET 1.1 to .NET 4.0. I also had to update the ASP Session State database to version 2 by running the following command in the command window.
aspnet_regsql.exe -S localhostSQL2005 -d ASPState -ssadd -sstype c -E
Is there any way that I can configure the MSI setup project to check the ASP.NET Session State and install version 2 if needed?
On my development machine, the session state data is retained after a post back to the server. (XP VS 2008) (This is true if running from within VS or if running in browser with localhost.)On the deployed test server, the session state is blank in IE, but works in Firefox. (Svr 2003 IIS 6)Both machines are running the exact same code with the exact same imputs and same web.config. There is no code between the post backs that write to the session state.Newest addition to the server would be the consumption of a WCF web service. Could this be a symptom of something missing on the server(s) when trying to connect with WCF? I could not find any information other than installing the 3.0 framework. I have 3.5 SP1 installed on the test server.
