State Management :: Session Objects Not Cleared As Expected After Upgrading To IIS7.5?

Sep 13, 2010

I've just upgraded my development machine from XP SP3 (IIS5.1) to Win7 x64 (IIS7.5)

Since doing this, my app has started to behave differently. Within it I store users' preferences/access levels using an instance of a class that I store within the Session object. This class is shown:

[Code]....

My requirement is that on each page request (other than the login page), the application should check that the Session object exists. The page data is therefore shown based on the values within the session object (e.g. which customer account they are using etc)...Previously on IIS5.1 if I was logged into the app, but made some changes to a file within App_Code, or Web.Config for example, when I then continued to use the app, I would get kicked out to the login page straight away. This is the intended behaviour. Now however, on IIS7.5, the app continues to provide access to the pages, but debugging shows that the session value has had all of its values set to 0 (zero). Therefore, the pages continue to load but the data shown is corrupted because the app no longer displays it accurately. Here is the code I use which (on IIS5.1) caught this occurence. Can anyone offer any advice on just what's now happening

[Code]....

I have tried changing this line:

State Management :: How To Link The Objects Between Browser Session And Session Objects

May 10, 2010

Lets say I am doing a shoping cart. I authenticate the user with a session variable.For example:

If(Request.IsAuthenticated)
// Here I want to add to the shoping cart.
// Can I do the following
Session["Cart"] = "Washing Machine";
Now will this Session["Cart"] value which is washing machine here be unique to diff customers?

State Management :: Manage Custom Objects And Session State?

Oct 6, 2010

I've created a whole bunch of rather complex classes and now i'm starting to work on the ASP.net user interface. Basically the user will open 1 page which will be used to load, edit, save an object. The object has many fields and they are often other classes i've created. To create a nice interface i've used popups and used AJAX to reload parts of the page to avoid reloading the whole thing.

My plan was to create the object and save it to the session. Then each time the page is loaded copy the object values to the asp fields and do the reverse when the page has been submitted copying the asp values to the object field then updating the session object.

So the code will go something like:

onload:

if session is not null load from session otherwise create new
this.txtID.text = object.id
this.txtName.text = object.name
etc etc

on submit:

object.id = this.txtID.text
object.name = this.txtName.text
etc etc
update session.

Is this what you guys would do? or am i over thinking this, seems like a lot of code to load all the object fields each time the page is opened and submitted etc.

Just looking to bounce ideas of off other developers :D

State Management :: Objects In Session Variables Now Causing Slow-downs?

Oct 24, 2010

I've noticed that once I've instantiated 3-4 objects now, my ASPX page is running slower. The response from the server (which is my own PC) is taking longer.

With one or two objects, the performance is same. After I instantiate 3, it slows a little, and 4 just completely wears it down.

I've read this article: [URL]

that says to avoid using session variables especially storing objects into them. Well thats exactly what I'm doing. My object has about 10 methods(~30 lines of code each) and 20 fields.

My question is, if I want to persist object in memory for each user session, how else could I store them on each postback if not in the session variable>? I can't use application variable because thats shared and not thread safe.

State Management :: Application State Is Not Cleared When Restart The Browser?

Feb 23, 2011

I am very new to asp.net. I developed one application. In that I have two pages. First page contains Application.Get() in page load event, here I read this Application variable, initially it returns NULL. If it is NULL, I make some buttons invisible. Then I jump to second page, in that page contains Application.Set(). Again I jump from second page to first page, this time Application.Get() is not NULL, I make some buttons visible.This is ok, if I execute the program in .net software.

But, when I publish this same program to web server like IIS, it is not working properly. After publishing very first time the first page returns NULL after that it doesnt return NULL even I closed the browser. I dont know why. In program, I used 2.0 framework. IIS also has 2.0 framework. Please clear this issue.

State Management :: Best Practise For Caching Objects For A List Of?

Dec 7, 2010

I've created a blog for my first asp.net website. Ive got a blog class as my object. Ive created a number of methods to access my blog articles using LINQ to SQL.

Each method returns a list of objects ready to be used in the appropriate web user control.

In my head i need to cache these lists of objects that are returned, but need to know the best way of approaching this. So i have come up with two possible options

1: Make one method to retrieve all blogs in a list<Blog> and cache this list to be used for all other methods or

2: Cache only the required methods that really need it.

State Management :: SessionState Works In VWD 2010 Debug, IIS 5.1 But Not On WS2008 (IIS7.5)

Sep 8, 2010

I'm building a site using the .NET 4 framework using routing and MasterPages.

Because I'm using both routing and MasterPages, I can't see any way how to get value from control on the previous page. To solve this I've used the code behind to store the control's value in a session variable. Is there a way to retrieve a value from a control using PreviousPage or something when using Routing and MasterPages?

This works fine in VWD debug mode and in IIS 5.1, but when I try to deploy it on my Windows Server 2008 (IIS7.5) machine, it get this error:

Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. 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.

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 :: Unable To Serialize The Session State In 'StateServer' And 'SQLServer' Mode

Dec 12, 2010

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.

State Management :: Asp Create New Session State Cookie Each Time On Debugging?

Jan 21, 2011

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?

State Management :: Losing Session State In Global.asax File?

Feb 2, 2011

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.

State Management :: Session State Expiration After Application Pool Recycle?

Nov 1, 2010

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.

State Management :: Session State Returning Null Values?

Apr 29, 2010

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?

State Management :: Session Variable Authentication State Timeout?

Dec 3, 2010

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?

State Management :: Accessing Session State In A User Control?

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 ...
