# 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 ##

```go
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](http://godoc.org/github.com/joeshaw/httpgzip).

Without gzip:

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

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