robustness in case of system crashes, but reduces performance. The
default is `true`.
- `hashed-mirrors`
A list of web servers used by `builtins.fetchurl` to obtain files by
hash. The default is `http://tarballs.nixos.org/`. Given a hash type
*ht* and a base-16 hash *h*, Nix will try to download the file from
`hashed-mirror/ht/h`. This allows files to be downloaded even if
they have disappeared from their original URI. For example, given
the default mirror `http://tarballs.nixos.org/`, when building the
derivation
```nix
builtins.fetchurl {
url = "https://example.org/foo-1.2.3.tar.xz";
sha256 = "2c26b46b68ffc68ff99b453c1d30413413422d706483bfa0f98a5e886266e7ae";
}
```
Nix will attempt to download this file from
`http://tarballs.nixos.org/sha256/2c26b46b68ffc68ff99b453c1d30413413422d706483bfa0f98a5e886266e7ae`
first. If it is not available there, if will try the original URI.
- `http-connections`
The maximum number of parallel TCP connections used to fetch files
from binary caches and by other downloads. It defaults to 25. 0
