RE: [WEB400] Pushing a PDF file with CGIDEV2

["Bob Cozzi" <cozzi@xxxxxxxxx>]

To simplify things...
Write the PDF on your IFS, then rather than read it and send it to the
browser, redirect the end-user to the PDF file using the Location: header.
You send that instead of the Content-type: header, something like this:

Location: http://www.mydomain.com//reports/293254.pdf\n\n

Where \n are linefeed characters.

Subject: [WEB400] Pushing a PDF file with CGIDEV2

Can I push a PDF file out to a web browser?

 

I wrote the following RPG program thinking it would work but I get garbage.
We are wanting to dynamically produce the PDF and then push to the user.
The main reason I wanted to push it out was so that I could delete the PDF
as soon as they are done.  Am I going about this the wrong way?
