Reverse proxying with Caddy and the Via header

1. The problem I’m having:

I want to measure the trade offs of proxying http requests and I’m using Caddy to conduct the experiment: GitHub - kaihendry/turtles

2. Error messages and/or full log output:

git clone
cd turtles
go run . -n 5
❯ curl -i localhost:8081
HTTP/1.1 200 OK
Content-Length: 27
Content-Type: text/plain; charset=utf-8

Server: Caddy
Server: Caddy
Server: Caddy
Server: Caddy
Server: Caddy

Hello, you've requested: /

You can see Server: Caddy was appended five times, though shouldn’t Via: be utilised?

I don’t understand. There’s lots of details missing here, and you deleted most of the help topic template. Please completely fill it out, as per the forum rules.
