The protocol defines the format of these messages and how the client and server exchange messages. The HTTP protocol is implemented by two parts of the program: a client program and a server program. The application layer protocol of the Web is the Hypertext Transfer Protocol HTTP. By inspecting the raw data in the packet content window, do you see any headers within the data that are not displayed in the packet-listing window? If so, name one.This article briefly introduces the theoretical knowledge of the Web application layer protocol, describes in detail the meaning of each field of the HTTP request message and the response message, and selects HTTP related messages from the Wireshark capture packet for analysis. 128 bytes of content are being returnedħ.How many bytes of content are being returned to your browser?

My browser indicates that it will accept English-US and English languages from the serverģ.What languages (if any) does your browser indicate that it can accept to the server? The server is also running http version 1.1Ģ.Is your browser running HTTP version 1.0 or 1.1? What version of HTTP is the server running? Step 2: Only capture http by using the filterġ.
