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.
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: */*
>
