WireShark Analysis of Cookie Forms

Analyzed one of the pages at leslienate.tech with wireshark
To isolate the packets sent to/from leslienate.tech We Used the filter for host name, which is contained in the header of http request
Contained in these packets is a lot of things, the ones we're familiar with are the TCP protocol and the HTTP protocol
The TCP protocol contains the port numbers sent and received from, acknowledgement flags [ACK, SYN, FIN, etc.], a sequence number with a randomly generated starting point and a payload among a few other things
The HTTP Protocol contains the host name, the method (POST, GET, PUT, PATCH, DELETE), content-type and cookies among a few other things.
It was interesting to see the cookies change as it lagged one behind each form submission and persisted between refreshes
The form data being submitted was also visible in the HTML Form URL encoded at the bottom.
