ReverseProxy is the Amazing Gem of the Go Std Lib
summary
Go's httputil.ReverseProxy is used to build a lightweight routing layer called Nomad that sits on aggregator hosts, uses an HTTP header with service ID to pick shards behind a feature flag, and enables rollouts pushed to the fleet in under a second so cross-aggregator windows shrink to 10–20 seconds. It also proxies traffic to a laptop for live debugging, compresses vendor payloads to 94% smaller with zlib, and tests via http/httptest and NewSingleHostReverseProxy.
