HttpContext.Current is giving wrong user information



I have used IIdentity WinId = HttpContext.Current.User.Identity; to get user information for the logged in user, but out of 5 user one user is getting other user's details. please suggest me how to sort out this issue.

I am not storing this details nor i processed before displaying it, i simply get value through above line and displaying it in the message box. So no question of overwriting by cookies or any other processes.

HttpContext.Current.User.IsInRole() caching roles on server


I am trying to authorize my users against AD groups via HttpContext.Current.IsInRole() method. However the roles are getting cached on the server. Say support, I add myself to a group and verify against that group, I am not getting authorized. Is it possible to clear cache everytime before verification or as soon as i add myself to a group the cache should get cleared.

I do not use membership provider or any such config keys in my vs2008 project.

Creating Sites/Lists/List Items under Current User Context in SharePoint By Using SPUserToken

Usually we do this by performing the action under RunWithElevatedPrivileges method and updating the listitem using SPListItem.SystemUpdate() method (see here). but this approach has its own flaws like (RunWithElevatedPrivileges will run under system account, we cannot use SystemUpdate for SPSite,SPWeb,SPList, since it runs under system we will "CreatedBy" by as SystemAccount).

Users getting logged out because HttpContext.Current is null


We've  been trying to fix this one for a couple years, and I'm just out of ideas, so any help is really appreciated!

We've got a fairly large, complex web application that uses Forms Authentication to authenticate users.  Throughout the application we store and retrieve information about users in the Session object, and in some cases in cookies.  In a couple places we check for the existence of the context, and if it's null we send the user back to the login page to re-establish the session. 

Just a quick run-down of this web app: C#, .NET 3.5, IIS 6, ASP.NET State Service to manage session

As for the session timer, we use our own home-grown timer, which is basically a client-side timer, which is backed up by a check to the SQL database to see when their last activity was.  This seems to work well for us.  It's not perfect, but it allows us to notify the user before the session times out, and allows us to be certain we're not logging a user out before their 60 minutes of inactivity is up.

What's happening is that certain users are being logged out after just a few minutes.  We've eliminated the timer as a cause and believe what's happening is the HttpContext.Current is null, so the user is logged out.  We do not know why the HttpContext.Current is null, and I underst

Knowing the event occured in user control in current page




      My web application has user control which uses third party controls called Devexpress controls. The user control is a menu  and is part of the Master page. It is placed there because this needs to be available in all the pages. My user controls raises a even on item clicked. Now, My question is that Is there any way to know that the event has occurred in page_load of the current page in which I am in?

hi, how can i create a current user filter in sharepoint designer?

The name 'User' does not exist in the current context.


Hey guys,

I've got a literal control to display the username of the user logged into our companies intranet system, originally I had a LoginName control but couldn't get strip to remove the domain from the username (as the format is domainname\username) so I'm trying it this way.

    protected void Page_Load(object sender, System.EventArgs e)
        string[] Parts = User.Identity.Name.Split("\\");

        if (Parts.Length == 2)
            loginName.Text = Parts[1];
            loginName.Text = User.Identity.Name;


    protected void Page_Load(object sender, System.EventArgs e)
        string[] Parts = User.Identity.Name.Split("\\");

How to determine if current SQL User is admin or owner?

Get current logon user id with SPContext.Current.Web.CurrentUser.LoginName

Hi all,I've been trying to search for the method to display the currently logon user id. So far, most sites I've visited used SPContext.Current.Web.CurrentUser.LoginName.I've tried this in my SharePoint custom application page. Everything works great.I have a test account, when logged in, was displayed as xxx\testacc.For some reasons, I changed the id in AD to xxx\test and did a full import to MOSS.I logged in to the custom application with the changed id, i.e. xxx\test, BUT the value of SPContext.Current.Web.CurrentUser.LoginName still displayed as xxx\testacc!How do I get the latest id? Has anyone encountered this before?Thank you.Kelvin

HTTPContext.Current.Session losing the variable sporatically

I have noticed a strange behaviour in my ASP.net 2.0 application. I have some logic in my aspx page that accesses some Session variables fine, then accesses some app_code and most of the time the HTTPContext.Current.Session returns the variable back fine.  However, I have noticed that sometimes this Session returns null, like it has lost it's "pointer" to the current HTTPContext. Is this a known bug, has anyone seen something like this before?   Any help would be appreciated, thanks, Mark. 

HttpContext.Current is null

I have an intermittent issue where HttpContext.Current is null.  I do have aspNetCompatibilityEnabled="True".  I can duplicate it by restarting the webservice and make the request.  The first request has the HttpContext.Current set to null but subsequent requests have the proper HttpContext.  I've done some tracing and the messages are exactly the same. What else is weird is that the HttpContext is NOT null in my global.asax but by the time it hits my custom UsernamePasswordValidator, it is set to null.   Any ideas on what i'm doing wrong?

current user identity in custom security trimmer

The crux of my problem is that I want to impersonate  a user’s NTLM credentials in the context of a SharePoint custom security trimmer to execute HttpWebRequests to check user access to URLs.  When accessing WindowsIdentity.GetCurent() in the security trimmer, the System.Security.Principal.WindowsIdentity object returns the identity of the application pool running the search query service, NOT the currently logged in user.   When accessing System.Threading.Thread.CurrentPrinciple.Identity in the security trimmer, the Microsoft.IdentityModel.Claims.ClaimsIdentity object of the current logged in user is returned.  However, there is a catch.  …   If I execute the following code in a .NET web application, the cast of the ClaimsIdentity to a WindowsIdentity succeeds because the identity has the authentication type of NTLM.    WindowsIdentity winId = (WindowsIdentity)System.Threading.Thread.CurrentPrincipal.Identity; WindowsImpersonationContext wic = winId.Impersonate(); request.Credentials = CredentialCache.DefaultCredentials; //access means a response comes back when a request is made to the url using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { returnStatus = true; } wic.Undo(); However, when I execute the same code in the context of the SharePoint security trimmer (the search query service li
