HTTP/HTTPS

  • HTTP: Hypertext Transfer Protocol, HTTPS: Hypertext Transfer Protocol Secure

  • Base-nya berjalan di TCP supaya reliable

  • Contoh flow:

 
Client: TCP handshake with server

Client: “GET /index.html HTTP/1.1”

Server: “HTTP/1.1 200 OK … (HTML data)”

  • HTTPS secure karena ada TLS handshake sebelum HTTP message saling dikirim
