Major Description
TSHttpTxnErrorBodySet(...) will usually be called in the plugin to set the body of the client response when error exists, but sometimes the header "Transfer-Encoding" will be inserted into the client response(from handle_response_keep_alive_headers(...)), and we should delete this header to indicate that the body was not chunked.
