NAME

       TSHttpTxnServerRespGet - TSHttpTxnServerRespGet API function

SYNOPSIS

          #include <ts/ts.h>

       TSReturnCode TSHttpTxnServerRespGet(TSHttpTxn txnp, TSMBuffer *bufp, TSMLoc *offset)

DESCRIPTION

       Get  the  response  header  sent  by  the  upstream  server. This will only be useful in a
       callback on a hook that is called after  the  upstream  responds,  and  if  there  was  an
       upstream  response.  For  instance,  if the inbound request has no remap rule and remap is
       required then there will be no server response because no outbound connection was made. In
       this case the function will return TS_ERROR.

       The  response  header is returned in bufp and offset. bufp is the heap in which the header
       resides, and offset is the location in that heap. These will be used in  subsequent  calls
       to retrieve information from the header.

          int get_response_status(TSHttpTxn txn) {
             TSMBuffer resp_heap = nullptr;
             TSMLoc resp_hdr = nullptr;
             if (TS_SUCCESS == TSHttpTxnServerRespGet(tnx, &resp_heap, &resp_hdr)) {
                return TSHttpHdrStatusGet(resp_headp, resp_hdr);
             }
             return HTTP_STATUS_NONE;
          }
