I want to send a binary file to the user and have some HTML display in the browser. I am using a CGI-BIN script with apache2. I found this example on page 4 . The link also shows detailed information about the multi-page / sibling type of content. Here is what I have tried so far:
Content-Type: Multipart / Related; boundary = "boundary-content"; start = ""; type = \ "text / plain \" "
--boundary-content
Content-Disposition: inline
Content Type: text / plain
Content-ID: <abc>
hi
--boundary-content
Content Type: application / octet-stream
Content-Disposition: attachment; filename = myfile
Content-ID: 2
...
--boundary-content
Content-Type . hi myfile ...?
