'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.
