Hi, Brian, Thank you very mcuh for your replying.
I think I don't need to maintain the seesion state. the client send a request to report servlet, the servet will generate a sessionID being save in a hastable, and send ID back to the client. then Every 15 seconds, the client will send a request with this ID to query the status of report (like how many the percentage is done). Could you tell me I need to care about fails over for this case? If there are 2 nodes, How to set up my every 15 seconds request will stick on the the first request node?
