Create a main.go file and copy-paste the following code snippets:

package main

import (


func main() {
    app := iris.New()

	// Configure sessions manager as we used to.
	sess := sessions.New(sessions.Config{Cookie: "mysession_cookie_name"})

    visitApp := mvc.New(app)



  • The VisitController.Session is automatically binded to the current sessions.Session.

  • The VisitController.StartTime is statically set to the server's start time with .Register(time.Now()) above.

type VisitController struct {
	Session *sessions.Session

	StartTime time.Time

func (c *VisitController) Get() string {
	// it increments a "visits" value of integer by one,
    // if the entry with key 'visits' doesn't exist
    // it will create it for you.
	visits := c.Session.Increment("visits", 1)
	// write the current, updated visits.
	since := time.Now().Sub(c.StartTime).Seconds()
	return fmt.Sprintf("%d visit(s) from my current session in %0.1f seconds of server's up-time",
		visits, since)


Open a terminal session and execute:

$ go run main.go
  1. Prepare a client, e.g. your browser

  2. navigate to http://localhost:8080

  3. refresh the page some times

  4. close the browser

  5. re-open the browser (if it wasn't in private mode) and re-play 2.
