(Note: a MIC is good for detecting accidental modification of the entity-body in transit, but is not proof against malicious attacks.) .. versionadded:: 0.9 HTTP_REFERERzThe Referer[sic] request-header field allows the client to specify, for the server's benefit, the address (URI) of the resource from which the Request-URI was obtained (the "referrer", although the header field is misspelled).Z HTTP_DATENThe Date general-header field represents the date and time at which the message was originated, having the same semantics as orig-date in RFC 822.ZHTTP_MAX_FORWARDSzThe Max-Forwards request-header field provides a mechanism with the TRACE and OPTIONS methods to limit the number of proxies or gateways that can forward the request to the next inbound server.cCs&t|dst|jdd|_dSdS)N_parsed_content_typer)hasattrrrgetr#rrrr_parse_content_type_s   z1CommonRequestDescriptorsMixin._parse_content_typecCs||jdS)zLike :attr:`content_type`, but without parameters (eg, without charset, type etc.) and always lowercase.

Age values are non-negative decimal integers, representing time in seconds.r?rzContent-LengthaThe Content-Length entity-header field indicates the size of the entity-body, in decimal number of OCTETs, sent to the recipient or, in the case of the HEAD method, the size of the entity-body that would have been sent had the request been a GET.zContent-LocationzThe Content-Location entity-header field MAY be used to supply the resource location for the entity enclosed in the message when that entity is accessible from a location separate from the requested resource's URI.zContent-EncodingabThe Content-Encoding entity-header field is used as a modifier to the media-type.
