How To Modify MachineKey For Session State Server

Jul 20, 2010

I'm trying to implement a SessionState server to allow multiple web servers to share the same state. At first this will be the different dev machines, and later it'll be the different web servers in the web farm.

So far, I'm making good progress I think, but one of the requirements has me confused. In order to implement this, I need to make sure that all web servers are using the same machine key.

This is a sample MachineKey taken from my local dev machine:

[Code]....

If we have a Session State Server deployed locally, do I need to ensure that all other machines using this service (specifically, the other devs working on the same project, and then when we deploy to the web farm) have the exact same entry in their Machine.Config files?

Or do I have to somehow generate a new machine key that can apply to all the machines?

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.

State Management :: Session Mode State Server - Sending Asynchronous Request

Nov 5, 2010

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);

State Management :: Recreate State Session Database In SQL Server 2008?

Apr 5, 2010

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...

State Management :: Session Variable Worked On One Prod Server But Not On Another Server?

Nov 3, 2010

We recently migrated a web app from one Prod server (Prod 1) to another server (Prod 2). There is a session varialbe checked inside the page load event of the default master page. I have enabled session state both in web.config as well inside the pagedirective. The compilation went through without any issue. The web app is also running just fine on the server but the log file keeps logging a warning message. There is no run time error.

"System.Web.HttpException: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also 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."Any idea why this is happening on one server vs other?

Can Use SQL Server Session State With Sessions That Contain DataTables

Feb 2, 2011

I have inherited an ASP.NET 3.5 application that relies heavily on sessions and storing DataTables within them (I know - bad, bad, bad). The application pool on the remote shared hosting service indicated that memory is at full capacity and as a result customers are losing their shopping carts because of dropped sessions.

Ultimately the goal is to rewrite this code, but for the time being I would like to stabilize the site the best I can. The host has recommended I use SQL Server Session State instead of in-proc. I have no experience with this, so I'm hoping it's as simple as running the .sql against the database to configure SQL Server and updating the web.config.

Change Session Mode To State Server

Mar 23, 2010

My website session was expired within seconds. I tried every possible solution but problem was same. Now i changed my session mode to stateserver, but when i logout from website its giving error. 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. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: Unable to serialize the session state.

C# - Share Session Between Two Web Sites Using .net And State Server?

Aug 9, 2010

I have two exactly the same web sites hosted in two different machines under IIS 7.5.
ASP.NET state service is running on my machine and the web.config is updated in both sites with the following code:

<sessionState mode="StateServer" stateConnectionString="tcpip=192.168.1.77:42424" cookieless="false" timeout="120"/>

The allow remote connection is set to 1 in registry in order for the second web site to access the state server.Both web sites have the same machine key:

<machineKey validationKey="7CB8DF6872FB6B35DECD3A8F55582350FEE1FAB9BE6B930216056C1B5BA69A4C5777B3125A42C4AECB4419D43EC12F168FD1BB887469798093C3CAA2427B2B89"[code]....

Additionally both sites are configured in IIS to have the same Identifier.What I want to do is that both these sites share the same session data for example being able to do the following:

// At web site 1:
Session["key"] = "value"[code]....

The problem is that I can't manage to accomplish this test and really can't understand what I am doing wrong.

Unable To Serialize Session State - Server Errors

Oct 14, 2010

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.

IIS Session State Server Stops Working After 30-60 Minutes?

Feb 25, 2011

So we have three 2008 R2 Servers where two are configured to be web servers (IIS 7.5), and the third a session state server. I have set the SessionState and MachineKey settings in the applications web.config. After I restart the two web servers I can log into one server, then change the IP address to the other server, and I am still logged in. Success.

I can typically log in/out with any user account I want, change the ip address back and forth, and all is well until some random time between 30-60 minutes when I log in to one server, change the IP address, and the new server asks for credentials.

This is the sessionState setting in both web.configs:

<sessionState mode="StateServer" stateConnectionString="tcpip=xxx.xxx.xxx.xxx:42424" cookieless="false" timeout="30"/>

The application resides under the default web site, and uses the default application pool. I am using forms authentication with a timeout of 20 minutes. I am not receiving any error events on any of the three servers when this happens, and restarting the two web servers fixes the problem for a while. The two web servers are not clustered per-se, but will be served round-robin via a network device.

Is The Session Timeout Handled When Set SQL Server As State Handler

Apr 4, 2011

How, or maybe where, is the session timeout handled when you set SQL Server as state handler in an ASP.NET application?

Is it the .NET framwork who after loading session objects from the DB does a judgement on whether or not the objects are expired, or is it a job on the SQL Server itself that takes care of this? The reason I suspect (or even concidered) the latter possibility, is that the script that created the ASPState mentioned something about a ASPState_Job_DeleteExpiredSessions-element.

If it is so that it is an SQL Server job that cleans up, how often does this job trigger and how does it align with the timeout parameter in web.config?

State Management :: Session Expires Very Quick On Hosting Server?

I have this setting in web config for session.

[Code]....

On localhost works well. On the hosting server expires very quickly. Sometimes after a minute, and sometimes after a few minutes.

I tried mode="StateServer" and mode="SQLServer", but first works the same, other doesn't work. The next problem is that End_Session in global.asax doesn't executes if mode is not InProc. And I need this.

How could I achive that session expires only when browser is closed or other url is typed. Just setting timeout doesn't work.

Both are using tables from the MSSQL, the only difference resides in the App_Data folder, which is not in the MSSQL server, as the roles and membership are managed by the LocalSqlServer.
