Where 9112 fits
Why 9112 is special
It is what remains of HTTP/1.1 once the semantics were factored out: the framing, the line endings and the parsing rules that request smuggling exploits.
Not just a mathematical number
9112is also used in ways where ordinary arithmetic doesn't apply — each listed below with what genuinely does and doesn't follow from it.
- Mathematical number
A genuine quantity — its mathematical properties (prime, square, factors, and so on) are real facts about it.
A genuine quantity that ordinary arithmetic applies to — it can be prime, even, a perfect square, added to another number meaningfully, and so on.
- Code
Also used as a code — HTTP status codes.
An assigned identifier from a fixed registry or standard — its digits don't represent an amount, and arithmetic on it is meaningless (HTTP status 404 + 1 is not a 'better' status; it's a different, unrelated code).

HTTP/1.1's framing rules are what request smuggling exploits, which is why they were separated and tightened.
HTTP/1.1 message parsing is what remains once semantics are removed, and its framing ambiguity is what request smuggling exploits.

Technology & computing
RFC 9112 specifies HTTP/1.1 message parsing and connection management. Ambiguity between Content-Length and Transfer-Encoding framing is the basis of request smuggling.
