From small scope to big:

  • page
A single page.
Processing a request from client side. It can cross pages.
  • desktop
All pages serving the same URL, for one browser tab.
  • session
From user visit the web to user leave or timeout. All following pages are related to same session.
  • application
From the application service start to stop. It is cross session, cross users.

Note that, if you press "F5" to refresh the web page, it's a different desktop, but the same session.
