Continuations are activated when they receive an event or by
22
``TSContSchedule`` (which schedules a continuation to receive an event).
23
Continuations might receive an event because:
25
- Your plugin calls ``TSContCall``
27
- The Traffic Server HTTP state machine sends an event corresponding to
28
a particular HTTP hook
30
- A Traffic Server IO processor (such as a cache processor or net
31
processor) is letting a continuation know there is data (cache or
32
network) available to read or write. These callbacks are a result of
33
using functions such ``TSVConnRead``/``Write`` or
34
``TSCacheRead``/``Write``
