304 responses contains "Content-length" or "Transfer-encoding" headers. rxresp action expects to get a payload in this case, even if 304 reponses must not have any payload. A workaround was added to remove these headers from the 304 responses. However, a better solution is to only get the response headers from clients using rxresphdrs action. If a payload is erroneously added in these reponses, the scripts will fail the same way. So it is safe.
