Request HeaderAccept-Charset
Beispiel:
Accept-Charset: iso-8859-1, unicode-1-1;q=0.8
Original Beschreibung (engl.):
The Accept-Charset request-header field can be used to indicate what
character sets are acceptable for the response. This field allows
clients capable of understanding more comprehensive or special-
purpose character sets to signal that capability to a server which is
capable of representing documents in those character sets.
Accept-Charset = "Accept-Charset" ":"
1#( ( charset | "*" )[ ";" "q" "=" qvalue ] )
Character set values are described in section 3.4. Each charset MAY
be given an associated quality value which represents the user's
preference for that charset. The default value is q=1. An example is
Accept-Charset: iso-8859-5, unicode-1-1;q=0.8
The special value "*", if present in the Accept-Charset field,
matches every character set (including ISO-8859-1) which is not
mentioned elsewhere in the Accept-Charset field. If no "*" is present
in an Accept-Charset field, then all character sets not explicitly
mentioned get a quality value of 0, except for ISO-8859-1, which gets
a quality value of 1 if not explicitly mentioned.
If no Accept-Charset header is present, the default is that any
character set is acceptable. If an Accept-Charset header is present,
and if the server cannot send a response which is acceptable
according to the Accept-Charset header, then the server SHOULD send
an error response with the 406 (not acceptable) status code, though
the sending of an unacceptable response is also allowed.
