> Downloads can be "forced" already with Content-Disposition: attachment. It's just harder to do, and unfortunately that doesn't stop webmasters from trying. Popular PHP snippets for forcing download are among the most disgusting cargo-cult code I've ever seen — they're collection of self-contradictory and nonsensical HTTP headers, break caching and resuming, and often have security vulnerabilities.

Indeed; I've used those code samples, and since the entire area is
basically voodoo to me, I still have no idea which headers I sent did
anything and which are useless or even harmful cruft.  In general,
even well-educated authors have no clue what they're doing here.
