Content-Disposition:

How MIME contents should be disposed

RFC2183

The MIME Content-Disposition: header specifies how a MIME attached file should be handled. The form of the Content-Disposition: header looks like this:

Content-Disposition: parameter=value ...

Here, the value for this header is a sequence of one or more equates, each separated from the others by one or more space or tab characters. The legal parameters are shown in Table 25-12.

Table 25-12. Content-Disposition: parameters
Parameter	Description of value
`filename`	The name of the file into which to save the contents. This can be a full path specification. In general, automatically honoring this equate represents a risk.
`creation-date`	The original time and date the content was created.
`modification-date`	The time and date the content was last modified.
`read-date`	The time and date the content was last read.
`size`	The size in bytes of the content.

In general, the Content-Disposition: header should be advisory.
