### Example

```go

package main

import (

	"fmt"

	"net/http"

	"github.com/acoshift/cors"

)

func handler(w http.ResponseWriter, r *http.Request) {

	fmt.Fprintf(w, "OK")

}

func main() {

	h := cors.New(cors.Config{

		AllowOrigins:     []string{"localhost:8080"},

		AllowMethods:     []string{http.MethodGet, http.MethodPost},

		AllowHeaders:     []string{"Authorization"},

		AllowCredentials: true,

	})(http.HandlerFunc(handler))

	http.ListenAndServe(":8080", h)

}

```

or use with [middleware](https://github.com/acoshift/middleware)

```go

package main

import (

	"fmt"

	"net/http"

	"github.com/acoshift/cors"

	"github.com/acoshift/middleware"

)

func handler(w http.ResponseWriter, r *http.Request) {

	fmt.Fprintf(w, "OK")

}

func main() {

	h := middleware.Chain(

		cors.New(cors.Config{

			AllowOrigins:     []string{"localhost:8080"},

			AllowMethods:     []string{http.MethodGet, http.MethodPost},

			AllowHeaders:     []string{"Authorization"},

			AllowCredentials: true,
