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).

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.

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.
