NAME

       TSCacheRead  -  asks  the Traffic Server cache if the object corresponding to key exists in the cache and
       can be read

SYNOPSIS

       #include <ts/ts.h>

       TSAction TSCacheRead(TSCont contp, TSCacheKey key)

DESCRIPTION

       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.
