Demonstrating HTTP Traffic Analysis using Wireshark.
Identify requests (from client) and response packets.
Find HTTP version, response code/phrase, requested file (including size).
Observe single small file (e.g., simple html file) request/response behaviour and the request/response behaviour for a file that has already been received.
Observe how a larger file is sent in multiple segments
Observe multi-file (e.g., web page with image) request/response behaviour.
Observe request/response behaviour for a page that needs authentication.
