Answer 1

In your IHttpHandler (.ashx handler) handler make it implement the IReadOnlySessionState or IRequiresSessionState (if it needs to set anything) interfaces, like this:

public class MyHandler : IHttpHandler, IReadOnlySessionState
{
  public void ProcessRequest(HttpContext context) 
  {
    //You can use session here
  }
  public bool IsReusable { get { return true; } } //this may vary for you
}
