307
307 is the HTTP status code Temporary Redirect — like 302, but the method must not change.

Where 307 fits
Why 307 is special
307 exists because 302 was implemented wrongly for years. Browsers converted a redirected POST into a GET, contrary to the specification, and by the time anyone noticed too much depended on the behaviour to fix it. 307 was added to mean what 302 was supposed to mean, with the method preserved.
Not just a mathematical number
307is 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).

1 × 256 + 0 × 128 + 0 × 64 + 1 × 32 + 1 × 16 + 0 × 8 + 0 × 4 + 1 × 2 + 1 × 1 = 307

Hexadecimal

1 × 256 + 3 × 16 + 3 × 1 = 307
Read as powers of two: 256 + 32 + 16 + 2 + 1 = 307.
In historical numeral systems
Egyptian
3 coils of rope, 7 strokes
3 × 100 + 7 × 1 = 307. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
5 vertical wedges (sixties place), 7 vertical wedges (units place)
5 × 60 + 7 = 307. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
tau, then zeta, marked as a numeral
tau-zeta + keraia
tau + zeta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
shin, then zayin
shin-zayin
shin (300) + zayin (7) = 307, written in descending order.
Maya
3 bars (upper, twenties place) over 1 bar + 2 dots (lower, units place)
15 × 20 + 7 = 307. Places stack vertically with the smallest at the bottom, so the upper group is worth twenty times the lower.
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
307 was added because browsers had already broken 302: it means the same redirect while guaranteeing the request method survives.
302 and 307 request the same redirect; only 307 guarantees the method survives it. The pair exists because browsers implemented 302 wrongly and the wrong behaviour became too widespread to correct.
View 302 →Technology & computing
Browsers historically turned a redirected POST into a GET, contrary to what 302 specified. By the time this was widely noticed, too much of the web relied on the wrong behaviour to change it — so 307 was added to mean what 302 was supposed to mean. The specification now documents both the intent and the accident.
