Communicating Presentation Information in
Internet Messages:
The Content-Disposition Header Field
Status of this Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.
Abstract
This memo provides a mechanism whereby messages conforming to the
MIME specifications [RFC 2045, RFC 2046, RFC 2047, RFC 2048, RFC
2049] can convey presentational information. It specifies the
"Content-Disposition" header field, which is optional and valid for
any MIME entity ("message" or "body part"). Two values for this
header field are described in this memo; one for the ordinary linear
presentation of the body part, and another to facilitate the use of
mail to transfer files. It is expected that more values will be
defined in the future, and procedures are defined for extending this
set of values.
This document is intended as an extension to MIME. As such, the
reader is assumed to be familiar with the MIME specifications, and
[RFC 822]. The information presented herein supplements but does not
replace that found in those documents.
This document is a revision to the Experimental protocol defined in
RFC 1806. As compared to RFC 1806, this document contains minor
editorial updates, adds new parameters needed to support the File
Transfer Body Part, and references a separate specification for the
handling of non-ASCII and/or very long parameter values.
