Yes, there is a way to “dump” all headers on a VIO, would that not work with
the FetchSM? In e.g. background_fetch, we do
if ((data->vc = TSHttpConnect((sockaddr*)&data->client_ip)) != NULL) {
TSHttpHdrPrint(data->mbuf, data->hdr_loc, data->req_io_buf);
// We never send a body with the request. ToDo: Do we ever need to
support that ?
TSIOBufferWrite(data->req_io_buf, "\r\n", 2);
I.e. TSHttpHdrPrint( …);
