Use TSCacheWrite to write to a cache (see the sample Protocol plugin). Possible callback events include:

• TS_EVENT_CACHE_WRITE_READ - indicates the lookup was successful. The data passed back along with this event is a cache vconnection that can be used to initiate a cache write.

• TS_EVENT_CACHE_OPEN_WRITE_FAILED - event returned when another continuation is currently writing to this location in the cache. Data payload for this event indicates the possible reason for the write failing (TSCacheError).
