Synopsis

#include <ts/ts.h>

TSReturnCode TSHttpTxnIsCacheable(TSHttpTxn txnp, TSMBuffer request, TSMBuffer response)

Description

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.

The request and response 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 txnp and the contents of the request and response, this returns TS_SUCCESS if the response is cacheable, TS_ERROR otherwise.
