# [Chi](https://github.com/go-chi/chi) proxy middleware
|
||||
|
||||
Forwarded headers middleware to use if application is run behind reverse proxy.
|
||||
|
||||
[](https://pkg.go.dev/github.com/chi-middleware/proxy)
|
||||
[](https://codecov.io/gh/chi-middleware/proxy)
|
||||
[](https://goreportcard.com/report/github.com/chi-middleware/proxy)
|
||||
[](https://cloud.drone.io/chi-middleware/proxy)
|
||||
|
||||
## 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),
|
||||
},
|
||||
}))
|
||||
```
