Find the HTTP GET message that was sent from your computer to the
gaia.cs.umass.edu HTTP server. (Look for an HTTP GET message in the “listing
of captured packets” portion of the Wireshark window (see Figure 3) that shows
“GET” followed by the gaia.cs.umass.edu URL that you entered. When you
select the HTTP GET message, the Ethernet frame, IP datagram, TCP segment,
and HTTP message header information will be displayed in the packet-header
window2
to the left side of the packet details window, minimize the amount of Frame,
Ethernet, Internet Protocol, and Transmission Control Protocol information
displayed. Maximize the amount information displayed about the HTTP protocol.
Your Wireshark display should now look roughly as shown in Figure 5. (Note, in
particular, the minimized amount of protocol information for all protocols except
HTTP, and the maximized amount of protocol information for HTTP in the
packet-header window).
