ASP.NET: How to access Session from handler? [duplicate]

Implement the System.Web.SessionState.IRequiresSessionState interface

public class Handler : IHttpHandler, System.Web.SessionState.IRequiresSessionState 
{   
  public void ProcessRequest(HttpContext context)  
  {      
    context.Session["StackOverflow"] = "overflowing";      
    context.Response.Redirect("~/AnotherPage.aspx");      
  }

}

Implement IRequiresSessionState

Does implementing iRequiresSessionState resolve this?

What about doing an IHttpModule instead and overriding BeginRequest?

    public void Init(HttpApplication application)
    {
        application.BeginRequest += new EventHandler(context_BeginRequest);
    }
