HTTP Streaming

The HTTP Streaming technique keeps a connection open indefinitely. It never closes, even after the server pushes data to the client.

In the case of HTTP streaming, the application sends a single request and receives responses as they come, reusing the same connection forever. This technique significantly reduces the network latency because the client and the server don't need to open and close the connection.

The basic life cycle of an application using HTTP-streaming is:

request --> suspend --> data available --> write response --> data available --> write response

The client makes an initial request and then suspends the request, meaning that it waits for a response. Whenever data is available, the server writes it to the response.
