What are Sessions?

Sessions allow storing user-specific data server-side that persists across multiple page requests. They are essential for personalized web applications.

🔄 GET

GET transmits data as URL parameters. They are visible in the browser and can be bookmarked.

  • Daten in URL sichtbar
  • Für Bookmarks geeignet
  • Max. ~2000 Zeichen

📨 POST

POST sends data in the request body. They are not visible in the URL and are suitable for forms and sensitive data.

  • Daten versteckt im Body
  • Sicherer für Passwörter
  • Keine Längenbeschränkung

💾 SESSION

Session data is stored server-side and persists across page requests.

  • Daten auf Server gespeichert
  • Über Seitenaufrufe erhalten
  • Für Login, Warenkorb, etc.
