Hi,
I am writing a simple chatting programming built over HTTP and allows people to chat with each other.
The way i am proposing to build the chat
servlet, is that when a user logs into the servlet with a user name and password i return the user id of the person over the response object. I also put the user id of the person along with the response object into a global hashtable. When a person say user_id 1 wishes to chat with a person say user_id 2, i read the global hashtable and obtain the user id 2 response object. On the response object i send the message that user_id 1 wants to send to user_id 2.
Could anyone tell me if this method works, or would they be a better way of achieving the above task. I know off course HTTP is connectionless so how else can we send a response to a user who has not initiated a request.
Kind Regards
