  • Evolving the Web: Discovering the History of HTTP Versions
    HTTP/1.1 was such a game changer for the Internet that it works so well that even through two revisions, RFC 2616 published in June 1999 and RFC 7230– RFC 7235 published in June 2014, HTTP/1.1 was extremely stable until the release of HTTP/2.0 in 2014 — Nearly 18 years later. Before continuing to the next section about HTTP/2.0, let us revisit what journey HTTP/1.1 has been through. - Source: dev.to / 11 months ago
  • Poll: Are client web requests sent to upstream servers or downstream servers?
    On the one hand, it just seems natural that "upstream" refers to the inbound request being sent from one system to another.

  • Show HN: Micro HTTP server in 22 lines of C
    It's neat, but I don't believe it is a compliant implementation of HTTP/1.1 (or 1.0). For example, it does not handle percent-encoded characters in the request URI.[1][2] [1]: https://datatracker.ietf.org/doc/html/rfc7230#section-3.1.1 [2]: https://www.w3.org/Protocols/HTTP/1.0/spec.html#Request-URI. - Source: Hacker News / almost 3 years ago
