State Management :: Session Gets Lost When Set Session Response.cookie
Jan 25, 2011
I need to make my asp.net session cookie as secure but whenever i check user authentication and after that i am trying to set cookie to true then my session lost my user information and so it always redirect login page. I am settings user to HttpContext.Current.Session["user"] and check every time, is user is valid and if valid then move ahead. but before that i make my asp.net session cookie as true.
[Code]....
but after that i observe that somehow "Session_Start" event gets called.

We have a local homepage, which connect to our production security environment. When I need to test my site in test environment, I need to get fresh cookie (not the one that was sent to me via production security service, when I opened IE with local homepage).
I am getting fresh cookie fine in Mozilla; but in IE I always have production cookie, and this disables my testing. What I should fix here?

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'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 would like to change ASP.NET session cookie name "ASP.NET_Sessionid" to some other name. I specified <sessionState cookieName="MyCookieName" />. When I use fiddler to view response header, I can see "MyCookieName" with random generated number under cookie section, however, ASP.NET_SessionId also exist there.

I am working on an asp.net website using C#. The site deals with orders and therefore order lines. I would like to store the order in memory whilst it is being populated (with order lines) and once it gets submitted write it to a database.
The above logic has been implemented, but sometimes when accessing session state or storing a variable in it information gets lost. Take note that the web server is running a dual-core processor. I am also using the in proc session state server.
I tried changing over to using the out proc session state server (asp.net state service), but it requires serialization. Since the order and orderlines are actually linq to sql classes, the entitysets and entityref's fail to serialize.
Does anyone know the reason why session state loses information occasionally and possibly how to eliminate the problem?

Existing applications works fine with IE 6 and 7, the problem occurs only with IE 8. A new session is created everytime a window.open is used to open a new asp page. This does not happen in IE 6 or 7.

I have a website for a simple game. When people sign in their Player ID is stored in a Session variable. I have integrated SMS payments so that my players can buy credits to use to play. This is where the problems start:
To buy credits, players are presented with an .aspx page that holds an IFRAME of the SMS payment proviers form. A code is entered, and the IFRAME POSTS to a URL on the providers server. It is then redirected back to an URL on my server(www.XXX.com/process.aspx), where I handle the results (i.e adds credits to th players account if the payment was successfull).
However, the session dies on return.
I tried with cookies, and saves the player ID in a cookie, but when upon return to www.XXX.com/process.aspx I cannot read the cookie? I'm checking for if (cookie == null) and it evaluates to TRUE, so the player is redirected to an error page.
How come the cookie cant be read? Is it because the POST is coming from an outside URL? And, what about when I do it with a session variable? Same thing there?

If I have two "webroles" (azure), that are NOT using a shared custom state provider, is the "Session.SessionID" be the same in both?It would make sense ,considering that both get the same cookie (because are in the same domain) and have the same machineKey, but I'm not sure

We have a web app running .net 1.1 that users must login to access (uses FormsAuthentication). At one point, the user submits a form that is handled by a separate web app on the same website but in a different directory (running .net 2.0 and not requiring authentication). When the user submits the form and is redirected to this other page they have some options including returning to the previous web app.
We need our users to stay logged in to the first web app so they do not have to log in again when returning. This works fine on 3 out of four computers, but the fourth computer is asked to log in when they hit the return button (by reviewing the active cookies we see that when it returns to the original web app, the FormsAuthentication cookie is missing)
why this cookie would disappear on one machine but not the others? I am going through IE settings now but the machine has the problem in IE and Chrome (not sure if this would be a shared setting) If it is an IE setting is there a way to make this work without requiring the user to change their settings and without switching to cookieless sessions?
Here is the authentication part of web.config
[Code]....
And if it makes a difference, the redirect and form action property use a the full path, would using a relative path likely change anything?

I have a problem with a couple of web sites where my session state gets lost prematurely.
I use the Inproc session provider and Asp.net 2.0. Which of these are true:
The antivirus software disturbs the session. IIS recycles the app pool every 2 hours and it does not retain the sessions during a recycle. Index server disturbs the session. Anything else that can have disturbed the session?

I am creating a presentation on basis of some selected values and maitaning the selected values in a session variable named Session("userPref") in collection form.
Now I am opening a TablePreview.aspx page by javascript window.open() function.
On Page_Load of TablePreview.aspx I am reading some values of Session("userPref") and doing some operatons.
For saving the presentation I have created a page wizardsave.aspx.
Now I am opening the wizardsave.aspx from TablePreview.aspx by window.open() function for saving presentation, but on Page_Load of wizardsave.aspx. I found that some value from collection stored in Session("userPref") have lost.

I have an issue of losing an InProc session variable when I call Response.redirect. I have seen a number of posts related to this, but haven't found a solution. My code is essentially:
Session("MyVariable") = "SomeBoolean"
Response.Redirect("NewUrl.aspx", false)
When I try to read Session("MyVariable") on the NewUrl.aspx page, it doesn't exists.
What's odd is that this doesn't typically happen in my local environemnt, but hapens quite often, if not all the time, on the shared server this application resides on. I saw some info about web farms and load balancing which could cause an issue. I am fairly certain this app is not part of a web farm.
A little background, in case there is a better method than using Session State...
I have created the ability for an administrator of this applicationto log in as any other user using a "Skeleton Key" password. When the admin does this, I store a boolean in session which refers to the fact that they are logged in and "Impersonating' another user. This gives the admin additional access that the user would not normally have. Anyhow, that is why I store a sessoin variable.

is it possible to create a new Session Id using C# and without using a Response.Redirect(...Page ... ). I want to create a new session Id on page load.
Reasons for doing so:
I have a testing application that creates IFrames to act as users. the problem I have is that with Multiple Instances (or Multiple IFrames running the same application "Default.aspx") all IFrame's are using the Same Session ID. I have variables stored in the Session ID that I need to be seperated from IFrame to IFrame. Ex:
IFrame 1 gets passed a query string of a client ID "1"
IFrame 2 gets passed a query string of client ID "2"
WHen the IFrame 2 gets loaded the session state of IFrame 1 inherits the IFrame 2's session's making the Client ID in Session 1 = "2". See what I am getting at?
I want to be able to have each IFrame create its own Session State. I guess there is 2 questions to this, 1.) is it possible to create a new Session State by abandoning the original and by doing so will that abandon both session ID's and just create an ID for both IFrames being the same ID? 2.) How can I do this if it is possible :-)

This is weird. In my newly developed chat application, when I invoke Response.Redirect, I am losing my session data. What is particualrly odd is that this sometimes seems to occur after a slight delay, so I reach the page, and then the session info gets lost momentarily thereafter. Mostly though it seems to get lost immediately. I have of course googled this issue, but yet to find anything that speaks to my problem. SessionState is in InProc mode. Session state has been working fine for me until this unexpected problem, so everything is configured right. So far the only workaround I can think of is to use a link instead of a button, and use javascript to call a server-side function on onclick to do the work I need to do before the link gets invoked. Messy, and I'd rather not go that way unless there's no alternative.
Just to preempt one red herring, I do use Response.Redirect(<address>, false).
The problem occurs both on the testing and production servers. I'm running ASP.NET 3.5 on IIS7.

I have an ASP.NET 2.0 site that stores a user's ID in session to indicate that they are logged in. In some situations, the user doesn't appear to stay logged in. I've been monitoring traffic in Fiddler, and some details I've found: The problem is 100% repeatable on an older laptop of mine when running IE7 and the project manager's laptop when running IE7. The problem does not ever occur on my current laptop running IE7, or any of these laptops when running FF. The problem occurs only in production--not on development, internal staging, or client staging. Production is the only load balanced environment, but the repeatability noted above makes me question load balancing as a factor.
When the page which sets Session("ID") = 1 sends a response back to the client, I can see a "Set-Cookie" header in all cases, which is creating the ASP.Net_Session_Id cookie (and it's HttpOnly). Subsequent requests to the server will send that cookie in the header on machines which are not exhibiting the problem, but not on machines that are, so either the cookie is getting deleted or the "Set-Cookie" header is being ignored.
The way logging in works is as follows: a page on [URL] has an iframe. The source of that iframe is a page on [URL]. A variety of pages served from [URL] take the user through the login/register process. The final step of [URL] is to redirect to a page back on [URL], including the user's ID in the querystring. This page on [URL] typically stores the ID in session, and then runs some JS to redirect the top level document to a new page, thus taking the user out of the iframe. This is a process that has worked for several years, with several values of [URL]. The one thing that may be different here is that in this case, the JS is simply destroying the iframe and some containing div's.
Another difference I see between scenarios where the problem occurs and where it doesn't is in the Google Analytics cookies. There is a difference when [URL] does its redirect to [URL] inside the iframe. When the problem does not occur, the request for SaveTheID.aspx includes a variety of Google Analytics cookies (__utma, __utmz, etc). When the problem does occur, this request does not include all the GA cookies (it's missing __utma, __utmz and __utmb). Production is the only environment where [URL] runs under SSL, so I thought that may be related. But we temporarily set up our staging copy of [URL] to use SSL, and that had no effect.

I added the following code to global.asax to load up several session variable when a session starts. I'm assuming that when a page goes to use the variable that I should be
1) checking at the page level that the value is valid not 0 when its not expected to be 0, not a zero-length string when its expected to have a length
2) have code at the page level that sets the values if the values have not been set as when the Session timeout, ideally putting the code in a class derived from Page and then deriving all of my pages from the new class so that the code does not have to be repeated in every page
[Code]....
