I have a node.js server which is communicating from a net socket to python socket. When the user sends an asynchronous ajax request with the data, the node server passes it to the python and gets data back to the server and from there to the client.
The problem occurs when the user sends the ajax request: he has to wait for the response and if the python process takes too much time then the ajax is already timed out.
I tried to create a socket server in node.js and a client that connects to the socket server in python with the data to process. The node server responds to the client with a loading screen. When the data is processed the python socket client connects to the node.js socket server and passes the processed data. However the client can not request the processed data because he doesn't know when it's done.
