NAME¶
TSCacheRead -
SYNOPSIS¶
#include <ts/ts.h>
- TSAction TSCacheRead(TSCont contp,
TSCacheKey key)
DESCRIPTION¶
Asks the Traffic Server cache if the object corresponding to
key exists
in the cache and can be read.
If the object can be read, the Traffic Server cache calls the continuation
contp back with the event
TS_EVENT_CACHE_OPEN_READ. In this
case, the cache also passes
contp a cache vconnection and
contp
can then initiate a read operation on that vconnection using
TSVConnRead.
If the object cannot be read, the cache calls
contp back with the event
TS_EVENT_CACHE_OPEN_READ_FAILED. The user (
contp) has the option
to cancel the action returned by
TSCacheRead. Note that reentrant calls
are possible, i.e. the cache can call back the user (
contp) in the
same call.
