HTTP has a new method: QUERY. Tl;dr: GET with a body.

The HTTP QUERY Method
This specification defines the QUERY method for HTTP. A QUERY requests that the request target process the enclosed content in a safe and idempotent manner and then respond with the result of that processing. This is similar to POST requests but can be automatically repeated or restarted without concern for partial state changes.

The #python library #aiohttp uses #yarl for URLs internally, and yarl normalizes URLs by default. It silently decodes some %-encoded characters in the query string that do not strictly need to be encoded.
Sounds harmless, but it isn't. Changing the URL breaks any protocol that signs important […]

The beauty of #foss: If the situation is bad enough for long enough, someone will come up with a solution. I try to be that someone from time to time.

I propose replacing calories with watt-hours.

- more intuitive for people who use electricity

I really like the zip-bomb idea to waste AI crawler resources and tweaked it a bit.
My version is now also a tar pit (infinite pages, rate-limited) and not only expands to ~8GB of HTML, but also lots of DOM nodes that are extra taxing on the layout engine of headless browsers.
