2068
RFC 2068 was the first specification of HTTP/1.1.

- Composite
Where 2068 fits
Why 2068 is special
It introduced persistent connections, which stopped browsers opening a new TCP connection for every image on a page.
Not just a mathematical number
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).

Read as powers of two: 2,048 + 16 + 4 = 2,068.
In historical numeral systems
Egyptian
2 lotuses, 6 hobbles, 8 strokes
2 × 1,000 + 6 × 10 + 8 × 1 = 2,068. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 4 vertical wedges (sixties place), 2 corner wedges + 8 vertical wedges (units place)
34 × 60 + 28 = 2068. Places are separated by a space on the tablet, with the higher place written first.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Related numbers & connections
HTTP/1.1 introduced status codes including 100, 206 and 409 that HTTP/1.0 did not define.
RFC 2068 was the first HTTP/1.1 specification and was replaced by RFC 2616 two years later.

Technology & computing
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.
