Where 300 fits
Why 300 is special
300 is the redirect nobody uses. It was designed for content negotiation, offering a client alternative formats or languages to choose between, but in practice servers decide for you and answer with the chosen representation directly. It survives in the specification more as a design record than as working infrastructure.
Same number, different meanings

- History
Thermopylae is remembered as 300 Spartans, and roughly 7,000 Greeks held the pass for the first two days. About 1,100 Thespians and Thebans stayed for the final stand alongside the Spartans. The figure 300 is accurate about one contingent and misleading about the battle.
- Sport
Twelve consecutive strikes score 300 in ten-pin bowling — twelve rather than ten because the final frame grants two extra deliveries. It is the maximum possible score, and unlike most perfect performances it is common enough that leagues record hundreds each year.
