.aspx sessions being called in .ashx handler

I have an Handler.ashx file and on .aspx page load it calles the .ashx file for image reading. I am attempting to pass a session from the .aspx file to the .ashx file in order to make my query of grabing the image secure. The problem is that everytime I call a session: HttpContext.Current.Session["ID"], the value is returning null or errors saying the o so commong "Object reference not set to an instance of the object". I have tried a couple ways of grabing the session:

1.) context.Session["ID"]

2.) HttpContext.Session["ID"]

3.) HttpContext.Current.Cache["ID"]

none of them are giving me the ID session set in the .aspx page. should i be using Server.Transfer instead? is there a way to grab a session variable set in a .aspx page and called in a .ashx page?

Any suggestions would be appreciated,
