Answer 1

HttpContext.Current.Session["..."]

HttpContext.Current gets you the current ... well, Http Context; from which you can access: Session, Request, Response etc

Answer 2

If you haven't changed thread, you can use HttpContext.Current.Session, as indicated by jwwishart.

HttpContext.Current returns the context associated with the thread. Obviously this means you can't use it if you've started a new thread, for example. You may also need to consider thread agility - ASP.NET requests don't always execute on the same thread for the whole of the request. I believe that the context is propagated appropriately, but it's something to bear in mind.

On the other hand, I'm not sure whether you'll even have a session for an AJAX Page Method. You can try it, but I'd be somewhat nervous of it. Ideally you should pass all the information you need from the client instead.
