title: Exactly how do I specify the location of the PDF template in a FDF file?
body: <p>I've written a PHP server script that downloads a FDF file to the user when he clicks on a button. This FDF was generated with dummy values for form fields with Acrobat Pro from the original interactive PDF template. I replace the dummy arguments in the PHP code and download the result to the user.</p>
  
  <p>My problem is that Acrobat starts up but cannot find the corresponding PDF. I've inserted the complete URL of the template PDF in the /F and/UF fields of the FDF, but it doesn't seem to work. The template URL has the same path as the FDF (except for the actual filename extension). What might I be doing wrong?</p>
