As with all multipart MIME types, each part has an optional "Content-Type" header that defaults to "text/plain". User agents should supply the "Content-Type" header, accompanied by a "charset" parameter.
All Document Modes (All Versions)
The Content-Type header is omitted except when an INPUT
element has type = file
. For INPUT
elements of type = file
, the Content-Type
is provided, but charset is omitted and a default of UTF-8
encoding is used.
