Where 2068 fits

2068 connects to 2 worlds: technology, related numbers.

It introduced persistent connections, which stopped browsers opening a new TCP connection for every image on a page.

2068is 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).

Documented appearance

HTTP/1.1 introduced status codes including 100, 206 and 409 that HTTP/1.0 did not define.

Connection

RFC 2068 was the first HTTP/1.1 specification and was replaced by RFC 2616 two years later.

RFC 2068 defined HTTP/1.1 including keep-alive connections, chunked transfer encoding and the Host header, the last of which made name-based virtual hosting possible. It was obsoleted by RFC 2616.
