## Adicione headers customizados

Há certas situações em que é bastante útil poder adicionar headers customizados no HTTP error. Exemplo disso seria adicionar headers customizados para tipos de segurança.

Você provavelmente não precisará utilizar esses headers diretamente no seu código.

- *If total drives has many common divisors the algorithm chooses the minimum amounts of erasure sets possible for a erasure set size of any N*.  In the example with 1024 drives - 4, 8, 16 are GCD factors. With 16 drives we get a total of 64 possible sets, with 8 drives we get a total of 128 possible sets, with 4 drives we get a total of 256 possible sets. So algorithm automatically chooses 64 sets, which is *16* 64 = 1024* drives in total.
