Dear HttpClient Users, I am using an Apache HttpClient5 to make CONNECT requests through an HTTP tunneling forward proxy. I would like to measure the backend latency after the tunnel connection is established between the proxy and the target server.
Specifically, is there a way to determine the duration between: 1. The proxy client establishing the tunnel connection with the target server, and 2. The client receiving the first byte of the response from the target server? Thank you for your assistance. Best regards, Sneha
