Question

HttpContext.Current.Session is null which inturn causing issues in my web application

Harsha Vardhan Medaboyina 0

I set up web application in my laptop and configure sessionstate as InProc but fail to create new HttpSessionStateWrapper(HttpContext.Current.Session) which is throwing HttpContext.Current.Session can not be null when I debug in Visual Studio 2019.

 public JarSessionWrapper SessionWrapper
        {
            get
            {
                if (_sessionWrapper == null && HttpContext.Current != null)
                {
                    _sessionWrapper = new 	JarSessionWrapper(new HttpSessionStateWrapper(HttpContext.Current?.Session));
                }

                return _sessionWrapper;
            }
        }

  public JarSessionWrapper(HttpSessionStateBase session)
        {
            this.session = session;
        }

        public JarSessionWrapper()
        {
            session = new HttpSessionStateWrapper(HttpContext.Current.Session);
        }

i was getting null in the values

HttpContext.Current.Session

thats pReventing to pass the login check . same thing used by others working it s an issue only in my system

We implemented this session wrapper for personalization rule in Sitecore and the weird thing is on my laptop it has issues and my colleague's laptop it is working fine. Do I miss any .NET packages or misconfigured IIS settings?

Hi @Harsha Vardhan Medaboyina,

In which project did you use the code above? Can you elaborate on the steps you developed and provide a configuration file.

You can check to see if you meet the following conditions.

If you have disabled the SessionState http module, disabling sessions altogether

If your code runs before the HttpApplication.AcquireRequestState event.

Your code runs in an IHttpHandler, that does not specify either the IRequiresSessionState or IReadOnlySessionState interface.

If you call a static method referencing the session via HttpContext.Current.Session.

Can you explain the use case for this design?

In my opinion, it is confusing to wrap Session in an instance object. Session's lifetime is the HTTP request. This design allows the wrapper class to be instantiated outside the Session's lifetime and cause a null exception.

As Viorel asked, can you show us where this code is called? Is the code called within an HTTP request?

If this is a standard API for your dev shop, perhaps asks the others to review your code.

Hi @Harsha Vardhan Medaboyina,

We implemented this session wrapper for personalization rule in Sitecore

Have you tried getting HttpContext.Current.Session outside of Sitecore?

If this is an issue in Sitecore and you need to speak to a professional, you can head over to the Sitecore forums for help.
