Questions tagged [content-disposition]

The Content-Disposition response header field is used in HTTP web responses to convey additional information about how to process a response payload. It can also be used to attach additional metadata such as a filename to the response.

The Content-Disposition response header field is used in HTTP web responses to convey additional information about how to process a response payload. It can also be used to attach additional metadata such as a filename to the response. The full definition of the content-disposition header is outlined in RFC 6266.

The content-disposition header is added to a HTTP response when further descriptive information is desired to aid the receiver in interpreting the payload. Usage follows the following grammar:

content-disposition = "Content-Disposition" ":" disposition-type *( ";" disposition-parm )

disposition-type = "inline" | "attachment" | disp-ext-type ; case-insensitive disp-ext-type = token

disposition-parm = filename-parm | disp-ext-parm

filename-parm = "filename" "=" value | "filename*" "=" ext-value

disp-ext-parm = token "=" value | ext-token "=" ext-value ext-token =

Questions related to this tag should be concerned with describing the payload of a HTTP Response. An example question may be - "Save a PDF that's been streamed to the browser"
