Traffic Server asynchronous Fetch API.
TSFetchUrl(const char*, int, sockaddr const*, TSCont, TSFetchWakeUpOptions, TSFetchEvent)¶
TSFetchCreate(TSCont, const char*, const char*, const char*, struct sockaddr const*, int)¶
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.
