-- The HTTP `Host` header must always be present and must specify the vault hostname. Example: `Host: contoso.vault.azure.net`. Note that most client technologies populate the `Host` header from the URI. For instance, `GET https://contoso.vault.azure.net/secrets/mysecret{...}` will set the `Host` as `contoso.vault.azure.net`. This means that if you access Key Vault using raw IP address like `GET https://10.0.0.23/secrets/mysecret{...}`, the automatic value of `Host` header will be wrong and you will have to manually insure that the `Host` header contains the vault hostname.
