I'm not that experienced with Chrome dev tools, so there might be a better way to do this, but here is an example of how to view HTTP headers:
Here's an example of HTTP headers as shown in the video:
-H 'sec-ch-ua: "Not-A.Brand";v="99", "Chromium";v="124"' \
-H 'Referer: https://hackerdaily.io/' \
-H 'DNT: 1' \
-H 'sec-ch-ua-mobile: ?0' \
-H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/124.0.0.0 Safari/537.36' \
-H 'sec-ch-ua-platform: "macOS"'
You can paste that into Chat GPT and ask it to explain what each line means:
curl 'https://hackerdaily.io/_nuxt/59062.js'curlcommand and the URL from which data should be fetched. Here, it's trying to retrieve a JavaScript file from the websitehackerdaily.io.Headers (

It's used for analytics, logging, or security (to check if requests are coming from expected pages).DNT: 1DNTstands for "Do Not Track," which is a request header indicating the user's preference regarding tracking. A value of1means that the user does not want to be tracked.sec-ch-ua-mobile: ?0?0means it is not a mobile device.User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/124.0.0.0 Safari/537.36User-Agentstring provides detailed information about the user's browser, operating system, and device. This can influence how websites behave or appear.sec-ch-ua-platform: "macOS"Here's an example of the headers added to the HTTP tool:
