## Usage

Import using:

```go
import "github.com/chi-middleware/proxy"
```

Use middleware with default options (trusted from proxy `127.0.0.1` and trusts only last IP address provided in header):

```go
    r := chi.NewRouter()
    r.Use(proxy.ForwardedHeaders())
```

Extend default options:

```go
    r := chi.NewRouter()
    r.Use(proxy.ForwardedHeaders(
        proxy.NewForwardedHeadersOptions().
            WithForwardLimit(2).
            ClearTrustedProxies().AddTrustedProxy("10.0.0.1"),
    ))
```

Provide custom options:

```go
    r := chi.NewRouter()
    r.Use(proxy.ForwardedHeaders(&ForwardedHeadersOptions{
        ForwardLimit: 1,
        TrustedProxies: []net.IP{
            net.IPv4(10, 0, 0, 1),
        },
    }))
```
