Exploring the HyperText Transport ProtocolYou are to retrieve the following document using the HTTP protocol in a way that you can examine the HTTP Response headers.http://data.pr4e.org/intro-short.txtThere are three ways that you might retrieve this web page and look at the response headers:Preferred: Modify the socket1.py program to retrieve the above URL and print out the headers and data. Make sure to change the code to retrieve the above URL - the values are different for each URL.Open the URL in a web browser with a developer console or FireBug and manually examine the headers that are returned.Enter the header values in each of the fields below and press "Submit".

Here are the steps to retrieve the document and examine the HTTP Response headers:

1. Modify the socket1.py program:

   • First, you need to have Python installed on your computer. If you don't have it, download and install it from the official Python website.

   • Open your Python IDE or text editor and create a new Python file named "socket1.py".

   • In this file, you will need to import the socket module, which provides the low-level networking functionality.

   • Then, create a socket object, connect to the server at "data.pr4e.org" on port 80, and send a GET request for "/intro-short.txt".

   • Finally, receive the response from the server and print it out. The first part of the response will be the headers, followed by the data.

Here is a sample code:

import socket

mysock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
mysock.connect(('data.pr4e.org', 80))
cmd = 'GET http://data.pr4e.org/intro-short.txt HTTP/1.0\r\n\r\n'.encode()
mysock.send(cmd)

while True:
    data = mysock.recv(512)
    if len(data) < 1:
        break
    print(data.decode(),end='')

mysock.close()

2. Open the URL in a web browser with a developer console or FireBug:

   • Open your web browser and navigate to the URL.

   • Open the developer console (usually by pressing F12 on your keyboard).

   • Go to the Network tab and refresh the page. You should see a list of all the network requests made by the page.

   • Click on the request for "intro-short.txt". The headers will be displayed in a panel on the right.

3. Enter the header values in each of the fields below and press "Submit":

   • This part of the question seems to be referring to a specific form or interface that isn't included in the question. You would need to enter the header values into the appropriate fields in this form or interface and then press the "Submit" button.
