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.
