In this blog, we will learn about Golang Gorilla Sessions NewCookieStore.

HTTP (Hypertext Transfer Protocol) being a stateless protocol does not store any kind of information about the previous requests and the user on the server. Every time a client requests a web page from the server, a new connection is started. But we can make our server stateful by using sessions.

When the server uses session, client sends the session ID to the server and the server then authenticates the ID and shows the web page according to the user.

Here is a simple example of Golang Gorilla Session NewCookieStore.

Golang Session Cookie

var cookie *sessions.CookieStore This creates a cookie variable to store sessions using secure cookies.

The init function which runs before the main function, a new cookie is created using the string provided in the parameter of the sessions.NewCookieStore() function.

Golang Session Authentication

golang session loginThe /login is used for the creation of the session. golang session unauthorized The / URL i.e the Home Page uses the session and authenticates it. If the session ID and Key match the successful message page.

Golang Session Authentication
Golang Session Logout

/logout path as the name suggests logs out from the current session. This leads to the deletion of session IDs and keys.

package main

import (


var cookie *sessions.CookieStore

func init() {
	cookie = sessions.NewCookieStore([]byte("Golang-Blogs"))

func home(w http.ResponseWriter, r *http.Request) {
	session, _ := cookie.Get(r, "Golang-session")
	var authenticated interface{} = session.Values["authenticated"]
	if authenticated != nil {
		isAuthenticated := session.Values["authenticated"].(bool)
		if !isAuthenticated {
			http.Error(w, "UnAuthorized to Access this Page.", http.StatusForbidden)
		fmt.Fprintf(w, "Authenticated User's Home Page")


func login(w http.ResponseWriter, r *http.Request) {
	session, _ := cookie.Get(r, "Golang-session")
	session.Values["authenticated"] = true
	session.Save(r, w)
	fmt.Fprintf(w, "Successfully Logged In")

func logout(w http.ResponseWriter, r *http.Request) {
	session, _ := cookie.Get(r, "Golang-session")
	session.Values["authenticated"] = false
	session.Save(r, w)
	fmt.Fprintf(w, "Successfully Logged Out")

func main() {
	http.HandleFunc("/", home)
	http.HandleFunc("/login", login)
	http.HandleFunc("/logout", logout)
	err := http.ListenAndServe(":8080", nil)
	if err != nil {
		log.Fatal("Error Starting the HTTP Server : ", err)

Run http-session.go using the go run command.
