WebAPI 2 attribute routing enable session state

Question

We figured out how to enable session state with webapi Sample here

Now we have WebApi 2 attribute routing, so we no longer have route object to inject custom handler

Answer 1

You can use the SessionStateUtility class to get the session state. Just call:

var session = SessionStateUtility.GetHttpSessionStateFromContext(HttpContext.Current)

Api controllers are designed for restful services and should generally be stateless. Not loading the session every time is one of the things that makes them lighter weight.

Answer 2

You need to add this to global.asax

protected void Application_PostAuthorizeRequest() 
{
    System.Web.HttpContext.Current.SetSessionStateBehavior(System.Web.SessionState.SessionStateBehavior.Required);
}

Then you could access the session through:

HttpContext.Current.Session

Answer 3

in the global.asax

Private Sub WebApiApplication_PostAuthorizeRequest(sender As Object, e As EventArgs) Handles Me.PostAuthorizeRequest
     System.Web.HttpContext.Current.SetSessionStateBehavior(System.Web.SessionState.SessionStateBehavior.Required)
End Sub
