## 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),
},
}))
```
