Distribution Instructions

DocuRights PDF files can be accessed on as many computers as have been pre-authorized. However, since the document is protected, you can distribute the file to any number of users in whatever manner you consider appropriate:
  • For Email Distribution... Attach the file to an email message, and send the email to as many people as you wish. An electronic reprint "use" will only be counted when the document is actually opened by the recipient.
  • For CD-ROM Distribution... Copy the file onto the CD-ROM, and send the disc to as many people as you wish. An electronic reprint "use" will only be counted when the document is actually opened.
  • For Web Site Distribution... Host the PDF file on your Web server, and allow users to download it. An electronic reprint "use" will only be counted when the document is actually opened.

To ensure the best user experience when providing a download facility from your Web server, please follow these instructions:

  1. Files must be named with the .FDF file extension to avoid automatic opening within a browser window (browser memory management is sometimes unstable when opening PDFs within the browser, and causes browser or system crashes).
  2. The PDF file must be sent to the user by a CGI, Active Server Page script, or some other means that has complete control of the HTTP headers that are sent to the client's browser. Simply putting a direct link to the PDF will more than likely cause the PDF to be opened in the Acrobat Reader plugin for that browser even when the file extension is .FDF.
  3. Use the following combinations of HTTP headers to force all web browsers to download the FDF file and save to disk instead of opening the FDF inside the web browser window. In the following, %s = filename; %u = length in bytes:

    1. For Netscape of any version on any platform use:
         Content-Type: application/octet-stream; name="%s.FDF"
         Content-Disposition: attachment; filename="%s.FDF"
    2. For Internet Explorer of any version on any platform EXCEPT MSIE 4.0 Win32 use:
         Content-Type: application/vnd.fdf; name="%s.FDF"
         Content-Disposition: attachment; filename="%s.FDF"
    3. For MSIE 4.0 Win32 explicitly use the following (note there are no quotes because MSIE 4.0 experiences difficulty with quotes in the Content-Type):
         Content-Type: application/octet-stream; name=%s.FDF
         Content-Disposition: attachment; filename=%s.FDF
    4. These HTTP headers must also be used when sending FDFs:
         Content-Transfer-Encoding: binary
         Content-Length: %u
