.SH DESCRIPTION
.sp
Determine if an upstream response is cacheable according to the current Traffic Server configuration and
state. All of the arguments must have be obtained via other API calls prior to calling this
function.
.sp
The \fIrequest\fP and \fIresponse\fP arguments must refer to HTTP header objects. These are
treated as the request and response for a transaction respectively. Based on the transaction state
from \fItxnp\fP and the contents of the request and response, this returns \fBTS_SUCCESS\fP if the
response is cacheable, \fBTS_ERROR\fP otherwise.
