music on my phone. One feature I like is the personalized playlist recommendations on the home screen. Behind the scenes, my device likely sends an HTTP GET request to Spotify’s servers asking for recommended tracks based on my listening history. The server processes this request, runs algorithms to select songs I might like, and sends back an HTTP response containing the playlist data in JSON format. My app then parses that response and displays the recommended songs for me to play instantly. question 2. Yes, this lab made me realize that every app or website I use is constantly sending and receiving HTTP requests in the background. Even simple actions, like loading a playlist or checking the weather, involve multiple requests and responses I never notice. It makes me appreciate how much coordination happens behind the scenes to make technology feel instant and seamless.

## Checkpoint 1
|
|
Read the request and response shown on lines 1-32 of the lab. Choose

five lines from the request and/or the response. For each, make an inference
|
|
about the meaning of the line, and some situation in which it might be useful.

You are welcome to research the meanings of these headers, but it's also
|
|
fine to speculate for now.
