If affinity is set to use multi core, aspnet_wp would be run individually on all cores.
So sessionstate, application and cache objects would be core specific. Is this understanding correct ?
Is there a way to share state - session, cache objects?
In my website I am maintaining cookies for the login so that if I open the browser again then no need to login again.
But when I am switching browser(from ie to ff or viceversa) then the cookies are lost and the user is not identified, I want to maintain them in this scenario also.
Is it possible to share a cache between multiple ASP.NET applications? The apps may reside on different servers. How can one achieve this requirement?
View 1 RepliesI have a website A which has a link to website B which is currently opening in a different window. When clicked on a link to, the login for B is automatically taken care of as both the websites have same user login credentials.
Now a change in the system has made me embed website B into website A. ie., B will open in the same window of A.. I could achieve this using an IFrame. Now, the session from site A needs to be carried out to site B. Presently, when navigated from A to B, all the sessions on A expire. Once navigated to B the session time out of B from the webconfig is taken. I have used "InProc" as my state management option in web config. Is it possible to maintain single session for both the webistes? If not how to continue same session times for both webistes? I do not want to use "SQL server" state mode.
I would like to share the session variables between 2 applications. basically I have a website and in there I have 2 applications and want to share the session object betwen the two. Is there a way to set something in web.config to enable this?
View 2 Replieshow do i pass data between two asp.net webservice sessions ?
this is the scenario, we've windows application and web service. our windows app calls a third party web site which requires data from our applciation. this 3rd party suggested that we create a web service that they can call from the web site.
after some reading it looks like i can use "application" object to store the data so that we store data in session with a specific session key and give it to web site and web site passes this session key in all methods it uses in webservice. is this best approach to take ?
I have an asp.net solution in which there are two web application projects (client website and admin website) and also a class liabrary project in the same solution . In the live production server, the admin web app is within the client app (eg: client site= [URL] and admin site=[URL]). A class (with static variables) in class liabrary is userd to cache data. My problem is that i cannot get the changes to the static cache by one web project reflected to the other (becoz, i think, they seem to load in seperate appdomains).
View 3 RepliesAfter doing some research, I found that <sessionState> can be hosted in SQL Server allowing applications to read from the same source. Essentially my app has two sides: a WCF library and an ASP.NET MVC 3 web site, the WCF has authentication and other DB IO methods and the MVC does the display. Now, the MVC stores a value in the session and then the WCF reads it and creates another for the MVC to read later. Problem is, neither can read each others session data, they can write to the same repository but can't share.
How do I go about them sharing the same information? How can I tell <sessionState> that the session started on the MVC side is the same as the WCF side and viceversa? I've tried
i have two solutions, 1. user management and 2. travel management. i publish the user management solution to [URL] and i publish the travel management to [URL] here i face the problem. the default home page would be [URL], its a windows authentication in page load, i capture the username, pass it to procedure which will fetch me his credentials on access. i store these in a session.
in the home page i have link to navigate to travel page, when i try to access the sessions in travel page, its empty. i tried printing the session id in both user management and travel, both are same but the sessions created in user management are empty in travel. what would be problem here and how can i resolve this.
If I want to share cookies among applications, applications need to be in the same domain. In production it is no problem. But I have problem with development. If I run those applications in Visual Studio, it runs application in "localhost" and it is not same domain. I don`t see cookies among applications.
View 1 RepliesI have 2 applications App1 and App2 on same domain, both with Forms authentication, each using a different database instance for authentication.
First, I open a browser with application www.mydomain.com/App1 and log on.
After that, when I open another instance of the same browser with application www.mydomain.com/App2 and log on, first browser loses session and goes back to login page.
I need each application on same domain to have its own session so that both can stay logged on.
I have two different IIS applications within the same domain(let us say www.mydomain.com) , both of these applications use the same database instance(same connectionstring), now what I want is that both of applications can see each sessions variables , can SQL Server session state mode helps in this case? Did someone try that before? Is there any other way to share the session variables?
View 3 RepliesI'm working on a pretty generic product purchase wizard that takes a user through a process to purchase items in a shopping cart. I am implementing it in MVC2 on Azure without session state. I want to do the following:
GET ShippingInfo calls ActionResult ShippingInfo()
POST ShippingInfo calls ActionResult ShippingInfo(ViewDataObject v)
In ShippingInfo action, I need to validate shipping info. If validation fails, it should redisplay the ShippingInfo view passing the ViewDataObject. If validation success, I want to display the ConfirmView using the posted ShippingInfo data in the ViewDataObject.
I have tried the following:
1) Called RedirectToAction("ConfirmView") but this requires the ConfirmView get method to read the ViewDataObject from cache or a database which I want to avoid if possible
2) Called View("ConfirmView") within the ShippingInfo action on validation success but the URL doesn't change so the back button doesn't work properly
3) Changed the form on ShippingInfo to post to the Confirm controller but then if validation fails the URL is on the Confirm page
I really want to just pass the limited form data from ShippingInfo to the ConfirmView. I then I have everything I need on the Post/Submit from the ConfirmView. Also I want the url to be /Order/Confirm when on the confirm page.
Is there a way to do this without TempData or session state?
I have multiple sites with main and subdomain. all doing one same method for the login. login is done with the multi domain cookie but there is problem with the logout. I'm using cookie and session for that state.
When ever I logout form the any domain. I should logout form the all domain.
(Like yahoo or google)
As per my method , My all domain have logout page which has code
[Code]....
and main site(www.domain.com) have
[Code]....
So what can I change in this code to do the Logout process for the all subdomains.
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 have a main domain "mydomain.com" and then a sub domain "forums.mydomain.com". If a user visits "forums.mydomain.com" without being logged in, they are redirected to "mydomain.com/login.aspx".
The two scenarios are:
If they are redirected to the login page with "mydomain.com/login.aspx?ReturnUrl=http://forums.mydomain.com", then they are succesfully logged into the forums but NOT the main site.
If they are simply redirected to the login page with "mydomain.com/login.aspx" with no returnUrl, they are correctly logged into both the main site and the forums.
when we go for client and server side state management in asp.net
View 2 RepliesIn 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.
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.

function SendRequest(msg, isBusy, chartMsg, vesselMsg)

Let me explain, describing the scenario:In a custom server control (in my case, derived from CompositeControl), in the overidden CreateChildControls method I create a complex tree of subcontrols, using information from a db.The db provides both information on which controls I need to create (the user interface's structure) and the data used to fill these controls.Than the user can interact with the control and change the data (that becomes different to what stored on db).
My custom control lives in the same page where there are other controls, obviously.And these controls can cause a postback at any time.What I need is that my custom control keeps the data entered by the user across these postback, without reverting to the original data and loose the user data entry.
Here is the first doubt:
1)I create the subcontrols dinamically in the CreateChildControls at any page refresh (both on first call than on postback).I know that the framework solves the reference between the posted data and the controls I create in the CreateChildControls in order to set properties and raise control events, but can you tell me when and how it actually does this? In which phase of page life cycle? What happens after the CreateChildControls?
A second doubt:2)If the user interface structure must change as a consequence of the data entered, I had to execute CreateChildControls twice (the first time to recreate the original interface to get the events and the second time to create the new interface)
In which phase of page/control lifecycle do I have to make the second call to CreateChildControls? I do it on Prerender now, but is it right or wrong, and why?
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.
I am having a ASP.net application it having three pages ,page 1,page 2,page 3,when the user navigating between this pages I want to maintain the view state in page level after postbacks(i.e.) .If a user visits page 3, passing some query loads some data .then he moves to page 1 doing some entries .after that he once again moves to page 3 now I want to display the data previously available at the time he moves to page 1, same
way I want to do to my three pages up to the user logging out.
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.
