title: "name" web pdf for better default save filename in Acrobat?
body: <p>My app generates PDFs for user consumption.  The "Content-Disposition" http header is set as mentioned <a href="https://stackoverflow.com/questions/74019/specifying-filename-for-dynamic-pdf-in-aspnet">here</a>.  This is set to "inline; filename=foo.pdf", which should be enough for Acrobat to give "foo.pdf" as the filename when saving the pdf.</p>
  
  <p>However, upon clicking the "Save" button in the browser-embedded Acrobat, the default name to save is not that filename but instead the URL with slashes changed to underscores.  Huge and ugly.  Is there a way to affect this default filename in Adobe?</p>
  
  <p>There IS a query string in the URLs, and this is non-negotiable.  This may be significant, but adding a "&amp;foo=/title.pdf" to the end of the URL doesn't affect the default filename.</p>
  
  <p>Update 2: I've tried both</p>
  
  <pre><code>content-disposition  inline; filename=foo.pdf
  Content-Type         application/pdf; filename=foo.pdf
  </code></pre>
  
  <p>and</p>
  
  <pre><code>content-disposition  inline; filename=foo.pdf
  Content-Type         application/pdf; name=foo.pdf
  </code></pre>
  
  <p>(as verified through Firebug) Sadly, neither worked.</p>
  
  <p>A sample url is</p>
  
  <pre>/bar/sessions/958d8a22-0/views/1493881172/export?format=application/pdf&no-attachment=true</pre>
  
  <p>which translates to a default Acrobat save as filename of</p>
  
  <pre>http___localhost_bar_sessions_958d8a22-0_views_1493881172_export_format=application_pdf&no-attachment=true.pdf</pre>

  This seems to be broken in FF (<a href="https://bugzilla.mozilla.org/show_bug.cgi?id=433613" rel="nofollow noreferrer">https://bugzilla.mozilla.org/show_bug.cgi?id=433613</a>) and IE but work in Opera, Safari, and Chrome. <a href="http://greenbytes.de/tech/tc2231/#inlwithasciifilenamepdf" rel="nofollow noreferrer">http://greenbytes.de/tech/tc2231/#inlwithasciifilenamepdf</a></p>
