    terminal. Applications open a session against `localhost:8194` and the
    terminal context is the authorization. No token is presented over the wire.

  parameter: X-BLPAPI-ASID
  description: |-
    Server API authorization is by ASID and registered IP address.
    The application's IP must be entitled in the Bloomberg Anywhere
    permissioning system; an `AuthorizationRequest` with `ipAddress`
    validates the user's identity at that location.

  description: |-
    B-PIPE applications acquire a token via the
    `AuthorizationTokenRequest` operation, then submit the token in an
    `AuthorizationRequest` to obtain an Identity object. The Identity
    object is then attached to subsequent service requests.
