I am trying to emulate server requests using curl command from client nodes (in this case, h3, h4) in mininet. To run the requests, I first started xterm terminals in mininet CLI to create nodes (h1, h2) as servers and (h3,h4) as hosts. I started python3 -m htt.server 80 in both h1 and h2 and tried to curl each of them using the command curl 10.0.1.1 from both h3 and h4 nodes. The 10.0.1.1 is the ip address of the pox loadbalancer controller and the servers 1 and 2 each have 10.0.0.1 and 10.0.0.2, respectively.
