----------------------------

how about this ?

int TSRespIsCacheable(TSHttpTxn txnp)
{
   sdk_assert(sdk_sanity_check_txn(txnp) == TS_SUCCESS);
 
   HttpSM *sm = (HttpSM *) txnp;
   HTTPHdr *req_hdr = &(sm->t_state.hdr_info.client_request);
   HTTPHdr *resp_hdr = &(sm->t_state.hdr_info.server_response);

   return HttpTransact::is_response_cacheable(&sm->t_state, req_hdr, resp_hdr);
}

> It would be useful for a plugin to be able to take e.g. a response header (a Hdr object) and ask the HttpSM if this response would be cacheable or not. It should use the same logic (and configs) as the core does normally.
