yo, i struggled with this too lol. env vars *can* work, but i prefer setting the proxy directly in code—more predictable.
for golang how to use forward http proxy, this is what i use:
```go
transport := &http.Transport{Proxy: http.ProxyURL(yourProxyURL)}
client := &http.Client{Transport: transport}
```
if auth's a problem, check out `golang.org/x/net/proxy` for SOCKS support. also, *always* handle errors properly—proxies love to fail silently.
