ASP.NET MVC - Session is null
asp.net, asp.net-mvc-3, session
Solution
Solution 1:
Link: HttpContext.Current.Session is null when routing requests
Got it. Quite stupid, actually. It worked after I removed & added the SessionStateModule like so:
<configuration>
...
<system.webServer>
...
<modules>
<remove name="Session" />
<add name="Session" type="System.Web.SessionState.SessionStateModule"/>
...
</modules>
</system.webServer>
</configuration>
Simply adding it won't work since "Session" should have already been defined in the `machine.config`.
Now, I wonder if that is the usual thing to do. It surely doesn't seem so since it seems so crude...
Solution 2:
Link: HttpContext.Current.Session null item
sessionKey may be changing, you probably only need to do:
HttpContext.Current.Session["CurrentUser"]
Or the session may be expiring, check the timeout:

Or you may be setting the session value from somewhere else, normally i control access to Session/Context object through one property
static readonly string SESSION_CurrentUser = "CurrentUser";
public static SiteUser Create() {
SiteUser.Current = new SiteUser();
return SiteUser.Current;
}
public static SiteUser Current {
get {
if (HttpContext.Current.Session == null || HttpContext.Current.Session[SESSION_CurrentUser] == null) {
throw new SiteUserAutorizationExeption();
}
return HttpContext.Current.Session[SESSION_CurrentUser] as SiteUser;
}
set {
if (!HttpContext.Current.Session == null) {
HttpContext.Current.Session[SESSION_CurrentUser] = value;
}
}
}
Problem
I have an MVC3 application on .net4 that its session working in the dev Environment, but not in the production. In the production I logged the sessionID and the it is the same in the moment I Set and Get from the session. When I try to get the session I am getting `Null Exception`. This is how I access the session: ``` public static class HandlersHttpStorage { public static string TestSession { get { return HttpContext.Current.Session["time"];//This is null } set { HttpContext.Current.Session.Add("time", value);//DateTime.Now.ToString() } } } ``` What's makes me worried is that the behavior in the production is different than the development, even though the web.config is the same.
