Web Forms :: 3.5 Error: Unable To Make The Session State Request To The Session State Server?
Dec 7, 2010
Have not run the ASP.NET Development Server for a while. Today I copied a production website to my workstation and ran it with VS 2008. The following error message popped up. What is the problem with the ASP.NET development Server on my workstation? The website on the Production server still ran okay.Unable to make the session state request to the session state server. Please ensure that the ASP.NET State service is started and that the client and server ports are the same. If the server is on a remote machine, please ensure that it accepts remote requests by checking the value of KEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesaspnet_stateParametersAllowRemoteConnection.
If the server is on the local machine, and if the before mentioned registry value does not exist or is set to 0, then the state server connection string must use either 'localhost' or '127.0.0.1' as the server name.

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.

We have been receiving reports of the following server error periodically from users.
[OutOfMemoryException: Exception of type System.OutOfMemoryException was thrown.]
[HttpException (0x80004005): Unable to serialize the session state.]
Please note that non-serializable objects or MarshalByRef objects are not permitted when session state mode is "StateServer" or "SQLServer".
Once in a state where this error appears, it appears to be hit or miss whether the errors are reproducible locally. If they are, then we can usually reproduce them for a couple minutes, but not on every page hit. This usually tapers off on its own and usually has resolved itself by the time we get back in contact with the users. The Web Service has around 90-100 active connections during business hours. The only other site on this server is the staging version of this site, which gets hit very infrequently. The Session State is stored on the same SQLServer instance as the application database which is housed on a fairly large cluster of virtual machines.
Neither the Web Server or the SQLServer seemed to be taxed (either processor or memory-wise) while this is going on. The distribution of which pages are erroring seems to be comparable to the normal distribution for each page. There doesn't appear to be any pattern in terms of times of occurrence. We do have less errors on average on weekends (which correlates to normal site load), but even this appears to not be consistent. There also doesn't appear to be a correlation between the errors logged and any kind of logged performance monitor events. This includes an array of perfmon counters including:

The only pattern I can see in the logs doesn't correlate to the occurrence of these errors, but is the only pattern I can see. Looking at the perfmon logs we are seeing a pattern where the "Total # of IL Bytes Jitted", "IL Bytes Jitted / sec", "% Time in Jit", "# of Methods Jitted", and "# of IL Bytes Jitted" counters for the staging site (which shouldn't be getting any traffic) doesn't pull data for a 20-50 minute period after which there is an immediate spike in "IL Bytes Jitted / sec" and a jump in "% Time in Jit" for 2-20 minute of up to 99% for the main site.

In my web application, I set the mode of session state as State Server and point to another server. After run some days, I always meet following exception:
The state server has closed an expired TCP/IP connection. The IP address of the client is 192.168.80.157. The expired Read operation began at 08/25/2010 14:18:03.

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 use some session variables to get the job done(shopping cart, etc) but it is not stable..manytimes I get no items in session object and other times(refreshing the page) I get missing data...I downloaded the entire site code to my local pc and debugged it and run it succesfully without any session data missing...When I run it in the server, I get bad session again: no products in shopping cart or products with missing quantities...
The same website runs smoothly in our production server too....The problem is with our development server...

just been trying to recieve the session value from multiple jquery ajax requests on the same domain name. i think i understand that each request is kind of a virtual browser request so the session is mutally exclusive to each request, but there must be a way some how, has anyone solved this. Basically this is what im trying to do:
I have tries using type: GET and POST but still no luck.

I'm writing a product management system for a website. As an administrator defines product details, those details are stored in the Session so that fields remain populated as the user navigates across multiple pages. One of these fields is a "RichTextBox" that allows the user to define a product description with rich text.
Attempting to pack the contents of this rich text box into a Session variable raises the following Server Error:
A potentially dangerous Request.Form value was detected from the client (ctl00_ContentPlaceHolder1_RichTextBox1_tbxRichContent="<b>asdf</b>").
The offending line of code is as follows:
Session["NewProductDescription"] = HttpUtility.HtmlEncode(RichTextBox1.Text);
I thought HtmlEncoding would solve the problem, but it did not.

I have a Dynamic Data application to which I have added a class for extending EDM. Everything works great, but now I am trying to set an entity property value equal to a value in session state - and its not recognizing the Session command. I'm trying to do something like this:
audit.action_by = CStr(Session("person_name"))
I think this is because I do not have the class Inheriting Page, but if I do add Inherits Page it breaks other stuff. How can I have the class include the ability to utilize sessions directly without inheriting Page?

I have noticed that when I have a session that has expired, the Session_OnStart event fires with every new request.
I suppose that this behavior is not normal, because I was expecting that the session would re-start only with the first request and not with every subsequent request.
This behavior occurs only with sessions where the timeout period has been exceded.
The current conditions under which I have experienced this problem are:
I have experienced this problem with an application that is using the .NET 2.0 framework and with a session mode configured to InProc. This problem is happening both on Windows XP SP3 and Windows 2003 Server.

I'm having trouble getting 2 identical ASP.NET MVC applications to share the same Session using a Session StateServer. The reason I'm trying to do this is we will eventually be deploying this app across 3 web servers that need to share the same state. We need to use StateServer because we are trying to minimise use of the db for non data-related storage.
The Setup: I've deployed the same code base to http://localhost/App1 and http://localhost/App2
both have identical Web.Config files with the following:
<system.web>
<sessionState mode="StateServer"
cookieless="false" [code]....
The Result:For both deployments, when the page first loads I can see that the mode is StateServer and the timestamp is getting set to the same time as the realtime value.. However, if this was working, only the first page should have the same time as the realtime value. The second page load should read from the StateServer because that timestamp value is no longer null, and display that time value. But instead, it's displaying the realtime value again.
When I refresh the page, I the timestamp stays the same and the realtime value is always updating. This indicates that the timestamp is being saved to the Session, but the time stamp value is always different for both deployments when it should be the same, so this indicates that the Session is not being shared.

We are setting session variables in the login page with all user details.And in all subsequent pages we check this session variable.This check is done in the page load of master page.As the number of users increased am getting error with these session variables.This session variable is returning me "nothing" when I check and the user is redirected to logout page.Interesting thing is that this is not happening always.

User Interface: 2 Labels; 1 Buttons
Requirements: Create a Web Page in ASPx that will do the following:
1)One label will provide a count of how many times Button 1 has been clicked in the current session.
2)One label will provide a count of how many times Button 1 has been clicked by all users of the application. The Application Code for the Button should start at 100 (set this in the Global.asax file). this is what i have so far but i cant seem to get the application state to work properly.

I've a class named baseClass.I can't access session variables from that class.This is the error i've got.
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration><system.web><httpModules> section in the application configuration.

I'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?
