Description¶

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.
