* by RFC7230#3.3.3 :
*
* The length of a message body is determined by one of the following
* (in order of precedence):
*
* 1. Any response to a HEAD request and any response with a 1xx
* (Informational), 204 (No Content), or 304 (Not Modified) status
* code is always terminated by the first empty line after the
* header fields, regardless of the header fields present in the
* message, and thus cannot contain a message body.
*
* 2. Any 2xx (Successful) response to a CONNECT request implies that
* the connection will become a tunnel immediately after the empty
* line that concludes the header fields. A client MUST ignore any
* Content-Length or Transfer-Encoding header fields received in
* such a message.
*
* 3. If a Transfer-Encoding header field is present and the chunked
* transfer coding (Section 4.1) is the final encoding, the message
* body length is determined by reading and decoding the chunked
* data until the transfer coding indicates the data is complete.
*
* If a Transfer-Encoding header field is present in a response and
* the chunked transfer coding is not the final encoding, the
* message body length is determined by reading the connection until
* it is closed by the server. If a Transfer-Encoding header field
* is present in a request and the chunked transfer coding is not
* the final encoding, the message body length cannot be determined
* reliably; the server MUST respond with the 400 (Bad Request)
* status code and then close the connection.
*
* If a message is received with both a Transfer-Encoding and a
* Content-Length header field, the Transfer-Encoding overrides the
* Content-Length. Such a message might indicate an attempt to
* perform request smuggling (Section 9.5) or response splitting
* (Section 9.4) and ought to be handled as an error. A sender MUST
* remove the received Content-Length field prior to forwarding such
* a message downstream.
*
* 4. If a message is received without Transfer-Encoding and with
* either multiple Content-Length header fields having differing
* field-values or a single Content-Length header field having an
* invalid value, then the message framing is invalid and the
* recipient MUST treat it as an unrecoverable error. If this is a
* request message, the server MUST respond with a 400 (Bad Request)
* status code and then close the connection. If this is a response
* message received by a proxy, the proxy MUST close the connection
* to the server, discard the received response, and send a 502 (Bad
* Gateway) response to the client. If this is a response message
* received by a user agent, the user agent MUST close the
* connection to the server and discard the received response.
*
* 5. If a valid Content-Length header field is present without
* Transfer-Encoding, its decimal value defines the expected message
* body length in octets. If the sender closes the connection or
* the recipient times out before the indicated number of octets are
* received, the recipient MUST consider the message to be
* incomplete and close the connection.
*
* 6. If this is a request message and none of the above are true, then
* the message body length is zero (no message body is present).
*
* 7. Otherwise, this is a response message without a declared message
* body length, so the message body length is determined by the
* number of octets received prior to the server closing the
* connection.

*
* The length of a message body is determined by one of the following
* (in order of precedence):
*
* 1. Any response to a HEAD request and any response with a 1xx
* (Informational), 204 (No Content), or 304 (Not Modified) status
* code is always terminated by the first empty line after the
* header fields, regardless of the header fields present in the
* message, and thus cannot contain a message body.
*
* 2. Any 2xx (Successful) response to a CONNECT request implies that
* the connection will become a tunnel immediately after the empty
* line that concludes the header fields. A client MUST ignore any
* Content-Length or Transfer-Encoding header fields received in
* such a message.
*
* 3. If a Transfer-Encoding header field is present and the chunked
* transfer coding (Section 4.1) is the final encoding, the message
* body length is determined by reading and decoding the chunked
* data until the transfer coding indicates the data is complete.
*
* If a Transfer-Encoding header field is present in a response and
* the chunked transfer coding is not the final encoding, the
* message body length is determined by reading the connection until
* it is closed by the server. If a Transfer-Encoding header field
* is present in a request and the chunked transfer coding is not
* the final encoding, the message body length cannot be determined
* reliably; the server MUST respond with the 400 (Bad Request)
* status code and then close the connection.
*
* If a message is received with both a Transfer-Encoding and a
* Content-Length header field, the Transfer-Encoding overrides the
* Content-Length. Such a message might indicate an attempt to
* perform request smuggling (Section 9.5) or response splitting
* (Section 9.4) and ought to be handled as an error. A sender MUST
* remove the received Content-Length field prior to forwarding such
* a message downstream.
*
* 4. If a message is received without Transfer-Encoding and with
* either multiple Content-Length header fields having differing
* field-values or a single Content-Length header field having an
* invalid value, then the message framing is invalid and the
* recipient MUST treat it as an unrecoverable error. If this is a
* request message, the server MUST respond with a 400 (Bad Request)
* status code and then close the connection. If this is a response
* message received by a proxy, the proxy MUST close the connection
* to the server, discard the received response, and send a 502 (Bad
* Gateway) response to the client. If this is a response message
* received by a user agent, the user agent MUST close the
* connection to the server and discard the received response.
*
* 5. If a valid Content-Length header field is present without
* Transfer-Encoding, its decimal value defines the expected message
* body length in octets. If the sender closes the connection or
* the recipient times out before the indicated number of octets are
* received, the recipient MUST consider the message to be
* incomplete and close the connection.
*
* 6. If this is a request message and none of the above are true, then
* the message body length is zero (no message body is present).
*
* 7. Otherwise, this is a response message without a declared message
* body length, so the message body length is determined by the
* number of octets received prior to the server closing the
* connection.

* by RFC7230#3.3.3 :
*
* The length of a message body is determined by one of the following
* (in order of precedence):
*
* 1. Any 2xx (Successful) response to a CONNECT request implies that
* the connection will become a tunnel immediately after the empty
* line that concludes the header fields. A client MUST ignore
* any Content-Length or Transfer-Encoding header fields received
* in such a message. Any 101 response (Switching Protocols) is
* managed in the same manner.
*
* 2. Any response to a HEAD request and any response with a 1xx
* (Informational), 204 (No Content), or 304 (Not Modified) status
* code is always terminated by the first empty line after the
* header fields, regardless of the header fields present in the
* message, and thus cannot contain a message body.
*
* 3. If a Transfer-Encoding header field is present and the chunked
* transfer coding (Section 4.1) is the final encoding, the message
* body length is determined by reading and decoding the chunked
* data until the transfer coding indicates the data is complete.
*
* If a Transfer-Encoding header field is present in a response and
* the chunked transfer coding is not the final encoding, the
* message body length is determined by reading the connection until
* it is closed by the server. If a Transfer-Encoding header field
* is present in a request and the chunked transfer coding is not
* the final encoding, the message body length cannot be determined
* reliably; the server MUST respond with the 400 (Bad Request)
* status code and then close the connection.
*
* If a message is received with both a Transfer-Encoding and a
* Content-Length header field, the Transfer-Encoding overrides the
* Content-Length. Such a message might indicate an attempt to
* perform request smuggling (Section 9.5) or response splitting
* (Section 9.4) and ought to be handled as an error. A sender MUST
* remove the received Content-Length field prior to forwarding such
* a message downstream.
*
* 4. If a message is received without Transfer-Encoding and with
* either multiple Content-Length header fields having differing
* field-values or a single Content-Length header field having an
* invalid value, then the message framing is invalid and the
* recipient MUST treat it as an unrecoverable error. If this is a
* request message, the server MUST respond with a 400 (Bad Request)
* status code and then close the connection. If this is a response
* message received by a proxy, the proxy MUST close the connection
* to the server, discard the received response, and send a 502 (Bad
* Gateway) response to the client. If this is a response message
* received by a user agent, the user agent MUST close the
* connection to the server and discard the received response.
*
* 5. If a valid Content-Length header field is present without
* Transfer-Encoding, its decimal value defines the expected message
* body length in octets. If the sender closes the connection or
* the recipient times out before the indicated number of octets are
* received, the recipient MUST consider the message to be
* incomplete and close the connection.
*
* 6. If this is a request message and none of the above are true, then
* the message body length is zero (no message body is present).
*
* 7. Otherwise, this is a response message without a declared message
* body length, so the message body length is determined by the
* number of octets received prior to the server closing the
* connection.
*/

* by RFC7230#3.3.3 :
*
* The length of a message body is determined by one of the following
* (in order of precedence):
*
* 1. Any 2xx (Successful) response to a CONNECT request implies that
* the connection will become a tunnel immediately after the empty
* line that concludes the header fields. A client MUST ignore
* any Content-Length or Transfer-Encoding header fields received
* in such a message. Any 101 response (Switching Protocols) is
* managed in the same manner.
*
* 2. Any response to a HEAD request and any response with a 1xx
* (Informational), 204 (No Content), or 304 (Not Modified) status
* code is always terminated by the first empty line after the
* header fields, regardless of the header fields present in the
* message, and thus cannot contain a message body.
*
* 3. If a Transfer-Encoding header field is present and the chunked
* transfer coding (Section 4.1) is the final encoding, the message
* body length is determined by reading and decoding the chunked
* data until the transfer coding indicates the data is complete.
*
* If a Transfer-Encoding header field is present in a response and
* the chunked transfer coding is not the final encoding, the
* message body length is determined by reading the connection until
* it is closed by the server. If a Transfer-Encoding header field
* is present in a request and the chunked transfer coding is not
* the final encoding, the message body length cannot be determined
* reliably; the server MUST respond with the 400 (Bad Request)
* status code and then close the connection.
*
* If a message is received with both a Transfer-Encoding and a
* Content-Length header field, the Transfer-Encoding overrides the
* Content-Length. Such a message might indicate an attempt to
* perform request smuggling (Section 9.5) or response splitting
* (Section 9.4) and ought to be handled as an error. A sender MUST
* remove the received Content-Length field prior to forwarding such
* a message downstream.
*
* 4. If a message is received without Transfer-Encoding and with
* either multiple Content-Length header fields having differing
* field-values or a single Content-Length header field having an
* invalid value, then the message framing is invalid and the
* recipient MUST treat it as an unrecoverable error. If this is a
* request message, the server MUST respond with a 400 (Bad Request)
* status code and then close the connection. If this is a response
* message received by a proxy, the proxy MUST close the connection
* to the server, discard the received response, and send a 502 (Bad
* Gateway) response to the client. If this is a response message
* received by a user agent, the user agent MUST close the
* connection to the server and discard the received response.
*
* 5. If a valid Content-Length header field is present without
* Transfer-Encoding, its decimal value defines the expected message
* body length in octets. If the sender closes the connection or
* the recipient times out before the indicated number of octets are
* received, the recipient MUST consider the message to be
* incomplete and close the connection.
*
* 6. If this is a request message and none of the above are true, then
* the message body length is zero (no message body is present).
*
* 7. Otherwise, this is a response message without a declared message
* body length, so the message body length is determined by the
* number of octets received prior to the server closing the
* connection.
*/
/* Skip parsing if no content length is possible. The response flags
* remain 0 as well as the chunk_len, which may or may not mirror
