# werkzeug.CommonResponseDescriptorsMixin¶

class werkzeug.CommonResponseDescriptorsMixin[source]

A mixin for BaseResponse subclasses. Response objects that mix this class in will automatically get descriptors for a couple of HTTP headers with automatic type conversion.

## Attributes¶

 age The Age response-header field conveys the sender’s estimate of the amount of time since the response (or its revalidation) was generated at the origin server. allow The Allow entity-header field lists the set of methods supported by the resource identified by the Request-URI. content_encoding The Content-Encoding entity-header field is used as a modifier to the media-type. content_language The Content-Language entity-header field describes the natural language(s) of the intended audience for the enclosed entity. content_length The 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. content_location The 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. content_md5 The Content-MD5 entity-header field, as defined in RFC 1864, is an MD5 digest of the entity-body for the purpose of providing an end-to-end message integrity check (MIC) of the entity-body. content_type The Content-Type entity-header field indicates the media type of the entity-body sent to the recipient or, in the case of the HEAD method, the media type that would have been sent had the request been a GET. date The 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. expires The Expires entity-header field gives the date/time after which the response is considered stale. last_modified The Last-Modified entity-header field indicates the date and time at which the origin server believes the variant was last modified. location The Location response-header field is used to redirect the recipient to a location other than the Request-URI for completion of the request or identification of a new resource. mimetype The mimetype (content type without charset etc.) mimetype_params The mimetype parameters as dict. retry_after The Retry-After response-header field can be used with a 503 (Service Unavailable) response to indicate how long the service is expected to be unavailable to the requesting client. vary The Vary field value indicates the set of request-header fields that fully determines, while the response is fresh, whether a cache is permitted to use the response to reply to a subsequent request without revalidation.
