NAME

       TSCacheRead - TSCacheRead API function

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.
