http headers do a lot, but here’s the simplest way I can put it: they’re like the metadata of a web request. They don’t contain the actual data (that’s the body), but they tell everyone how to handle it.

For example, `User-Agent` tells the server what browser you’re using, and `Location` tells your browser where to go next (like after a login).

If you wanna dig deeper, Mozilla’s docs (https://developer.mozilla.org/en-US/docs...TP/Headers) break it down nicely without being too technical.
