http_header:http_parse_header

Translate Value in a meaningful Prolog term. Field denotes the HTTP request field for which we do the translation. Supported fields are:

content_length: Converted into an integer
status: Converted into an integer
cookie: Converted into a list with Name=Value by cookies//1.
set_cookie: Converted into a term set_cookie(Name, Value, Options). Options is a list consisting of Name=Value or a single atom (e.g., secure)
host: Converted to HostName:Port if applicable.
range: Converted into bytes(From, To), where From is an integer and To is either an integer or the atom end.
accept: Parsed to a list of media descriptions. Each media is a term media(Type, TypeParams, Quality, AcceptExts). The list is sorted according to preference.
content_disposition: Parsed into disposition(Name, Attributes), where Attributes is a list of Name=Value pairs.
content_type: Parsed into media(Type/SubType, Attributes), where Attributes is a list of Name=Value pairs.
expires: Parsed into a time stamp using http_timestamp/2.

As some fields are already parsed in the Request, this predicate is a no-op when called on an already parsed field.

Arguments:

Value

- is either an atom, a list of codes or an already parsed header value.
