httpgzip-1's Introduction

httpgzip

httpgzip is a Go package that provides an http.Handle wrapper that transparently compresses the response payload with gzip if the Accept-Encoding: gzip request header is provided. It sets the Vary: Accept-Encoding and Content-Encoding: gzip response headers.

API

mux := http.NewServeMux()
mux.Handle("/", IndexHandler)
mux.Handle("/login", LoginHandler)

http.ListenAndServe(":8000", httpgzip.Handler(mux))

That's it. But it's also on godoc.

Without gzip:

$ curl -v http://localhost:8080/

> GET / HTTP/1.1
> User-Agent: curl/7.30.0
> Host: localhost:8000
> Accept: */*
>
< HTTP/1.1 200 OK
