Response

After the fourth packet, the server acknowledges the client's request to get to the web server's root directory. The server starts transmitting the resource that the client requested.

The sixth packet in the list pane is what the client received, a status code followed by a short message, including the content of the resource requested. Refer to the following screenshot illustrating the HTTP response:

HTTP response

As a part of TCP communication, the client will acknowledge every packet sent by the server, as seen in the seventh packet.

Let's dissect the response elements for packet number six: The first line consists of three arguments sent in response. They denote the HTTP

protocol version in use, the status code (304 in our case, which specifies

that the requested resource did not change since the time mentioned in

the Date parameter), and finally, a brief description of the status code (not modified in our case).

In the third line, the Server parameter mentions the name and version of

the web server. We can see that Apache/2.2.22 is the server that

is located at 172.16.136.129.

The fourth and fifth lines state that the server wishes to keep the connection alive. The duration for which the server wishes to do so is also mentioned in the next line of the parameters.
