Gmail inbox auto update, is this AJAX? How could I do this?
In Gmail once you received a new email it will update your inbox page with the new email without you reloading the page. How is Gmail doing this? How does Gmail knows I have a new email? From what I know AJAX only works if there's an action from a user, is this correct?
Please provide a sample code / a link to a tutorial on how I could do this.
