Welcome!

This simulator shows how an HTTP request travels from the PC to a server and how the answer comes back.

  1. Choose the protocol (HTTP, HTTPS or DNS) and the destination: the internal server or the public server on the Internet.
  2. Type the data to send, for example GET /index.html, Hello world or, for DNS, a name like www.example.com.
  3. Click Start simulation, then Next (or press →) to move the data one layer at a time.

You can change the IP address of the public server directly in the diagram.
