Question
You 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.
Solution
Here are the steps to retrieve the document using the HTTP protocol and examine the HTTP Response headers:
-
Modify the socket1.py program:
- Open the socket1.py program in a Python editor.
- Look for the line where the URL is defined. It might look something like this:
mysock.connect(('data.pr4e.org', 80)) - Replace the existing URL with the new one:
mysock.connect(('http://data.pr4e.org/intro-short.txt', 80)) - Run the program. The headers and data will be printed in the console.
-
Use a web browser with a developer console or FireBug:
- Open your web browser and navigate to the URL: http://data.pr4e.org/intro-short.txt
- Open the developer console. In most browsers, you can do this by right-clicking on the page and selecting "Inspect" or "Inspect Element."
- Click on the "Network" tab in the developer console.
- 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.
-
Use a command-line tool like curl:
- Open a command-line interface.
- Type the following command and press Enter:
curl -I http://data.pr4e.org/intro-short.txt - The headers will be printed in the console.
Remember, the values in the headers will be different for each URL, so make sure to use the correct URL for the document you want to retrieve.
