title: forcing a file to download
body: <p>I have a php page with information, and links to files, such as pdf files. The file types can be anything, as they can be uploaded by a user.</p>
  
  <p>I would like to know how to force a download for any type of file, without forcing a download of links to other pages linked from the site. I know it's possible to do this with headers, but I don't want to break the rest of my site.</p>
  
  <p>All the links to other pages are done via Javascript, and the actual link is to #, so maybe this would be OK?</p>
  
  <p>Should I just set </p>
  
  <pre><code>header('Content-Disposition: attachment;)
  </code></pre>
  
  <p>for the entire page?</p>
