Everything you need to know about HTTP

Just came here to ask the same thing.

It feels like a low-quality article to me - a lot of things are repeated and just feels like it's a copy-paste collection of snippets from various sources without the author understanding what it really talks about.

I hadn't thought of that, but maybe. There's some weird inaccuracies.

The paragraphs on HTTP/1.0 makes it sound like images weren't sent before HTTP/1.0, but NCSA Mosaic was doing exactly that before HTTP/1.0.

The whole bit about HTTP/2 server push neglects to mention that it's been effectively deprecated, which seems kind of like an important point.

Likewise, for request prioritization, it leaves out that HTTP/2's method is frequently worse than nothing (without a LOT of careful work, measurement, and tuning), and that HTTP/3 vastly simplified it.

There's a lot of repeated stuff for no reason. The congestion control and loss recovery sections are a struggle to read.

Ctrl-f "uses a combination of congestion control and loss recovery to recover from packet loss" or "This is similar to"

Various errors about the place too, e.g. the “HTTP is TCP” thing near the start (twice), and the HTTP/1.0 request sample includes a Host header (that came later), and has a User-Agent value suggesting a 2017 browser.

Yeah, the entire website looks like a content farm

Are you talking about https://www.stackscale.com/blog/http3/ or something else?
