Question

Does HTTP response follow the same path as HTTP request to serve?

Answer 1

By path, I assume you been the routing path between nodes in your network.

The response of an HTTP request is sent back to the client via an open TCP connection on the server, typically the same one used to send the request. Whether it takes the same path depends on the configuration of your network. In most cases it would take the same path within your network behind the load balancer. However, this isn't universally guaranteed.
