1. Install  gopkg.in/boj/redistore.v1 and github.com/gorilla/sessions using the go get command, as follows:

$ go get gopkg.in/boj/redistore.v1
$ go get github.com/gorilla/sessions

2. Create http-session-redis.go, where we will create a RedisStore to store and retrieve session variables, as follows:

package main
import 
(
  "fmt"
  "log"
  "net/http"
  "github.com/gorilla/sessions"
  redisStore "gopkg.in/boj/redistore.v1"
)
const 
(
  CONN_HOST = "localhost"
  CONN_PORT = "8080"
)
var store *redisStore.RediStore
var err error
func init() 
{
  store, err = redisStore.NewRediStore(10, "tcp", ":6379", "",
  []byte("secret-key"))
  if err != nil 
  {
    log.Fatal("error getting redis store : ", err)
  }
}
func home(w http.ResponseWriter, r *http.Request) 
{
  session, _ := store.Get(r, "session-name")
  var authenticated interface{} = session.Values["authenticated"]
  if authenticated != nil 
  {
    isAuthenticated := session.Values["authenticated"].(bool)
    if !isAuthenticated 
    {
      http.Error(w, "You are unauthorized to view the page",
      http.StatusForbidden)
      return
    }
    fmt.Fprintln(w, "Home Page")
  } 
  else 
  {
    http.Error(w, "You are unauthorized to view the page",
    http.StatusForbidden)
    return
  }
}
func login(w http.ResponseWriter, r *http.Request) 
{
  session, _ := store.Get(r, "session-name")
  session.Values["authenticated"] = true
  if err = sessions.Save(r, w); err != nil 
  {
    log.Fatalf("Error saving session: %v", err)
  }
  fmt.Fprintln(w, "You have successfully logged in.")
}
func logout(w http.ResponseWriter, r *http.Request) 
{
  session, _ := store.Get(r, "session-name")
  session.Values["authenticated"] = false
  session.Save(r, w)
  fmt.Fprintln(w, "You have successfully logged out.")
}
func main() 
{
  http.HandleFunc("/home", home)
  http.HandleFunc("/login", login)
  http.HandleFunc("/logout", logout)
  err := http.ListenAndServe(CONN_HOST+":"+CONN_PORT, nil)
  defer store.Close()
  if err != nil 
  {
    log.Fatal("error starting http server : ", err)
    return
  }
}

3. Run the program with the following command:

$ go run http-session-redis.go
