Response HeaderContent-Language
Beispiel:
Content-Language: de, en
Original Beschreibung (engl.):
The Content-Language entity-header field describes the natural
language(s) of the intended audience for the enclosed entity. Note
that this might not be equivalent to all the languages used within
the entity-body.
Content-Language = "Content-Language" ":" 1#language-tag
Language tags are defined in section 3.10. The primary purpose of
Content-Language is to allow a user to identify and differentiate
entities according to the user's own preferred language. Thus, if the
body content is intended only for a Danish-literate audience, the
appropriate field is
Content-Language: da
If no Content-Language is specified, the default is that the content
is intended for all language audiences. This might mean that the
sender does not consider it to be specific to any natural language,
or that the sender does not know for which language it is intended.
Multiple languages MAY be listed for content that is intended for
multiple audiences. For example, a rendition of the "Treaty of
Waitangi," presented simultaneously in the original Maori and English
versions, would call for
Content-Language: mi, en
However, just because multiple languages are present within an entity
does not mean that it is intended for multiple linguistic audiences.
An example would be a beginner's language primer, such as "A First
Lesson in Latin," which is clearly intended to be used by an
English-literate audience. In this case, the Content-Language would
properly only include "en".
Content-Language MAY be applied to any media type -- it is not
limited to textual documents.
