       Traffic Server provides a number of routines for fetching resources asynchronously.  These API are useful
       to support a number of use cases that may involve sideways calls, while handling the client request. Some
       typical  examples include centralized rate limiting framework, database lookups for login/authentication,
       refreshing configs in the background asynchronously, ESI etc.
