this compiles to 10kb on my machine with no golfing. it literally just supports grabbing whatever is at the url given (http 1.0)

I did a <4KB one that supports DNS+TLS (albeit insecurely) https://github.com/DavidBuchanan314/kurl/

This is of course great, and very creative, but why not use an HTTP proxy if this TLS is still unprotected?

Did I misunderstand something?

Many servers support TLS only, so implementing the client side of TLS was a matter of compatibility, not security. If external dependencies are allowed then why not just use libcurl?

Does this do anything curl can’t or are we just enthralled with the tininess?

Actually hfile has nothing new, So the basic philosophy here is a small binary.
