What Exactly Do HTTP Headers Do and Why Should You Care? or Can Someone Explain What HTTP Headers Do

12 Replies, 681 Views

Headers are the unsung heroes of the web. They handle redirects, compression, even which version of a file to send (looking at you, `Accept-Encoding`).

For performance, good headers can shave seconds off load times. Bad ones? They add pointless round trips.

Try the `Header Editor` extension to fiddle with them live. Or just copy what fast sites use (check with `curl -I`).

Wow, didn’t realize http headers do so much! The caching stuff makes total sense—I’ve def seen my site reload things it shouldn’t.

Gonna try Chrome DevTools and SecurityHeaders.com first.

Quick follow-up: anyone know if there’s a "cheat sheet" for the most important headers? Like a top 5 list for noobs? Thanks again!
