title: "Network failure" to download PDF generated with with PHP FPDF/FPDF2File class in Google Chrome
body: <p>I have reports generated in <strong>PHP</strong> / <a href="http://www.fpdf.org/" rel="nofollow noreferrer"><strong>FPDF</strong></a> / <a href="http://www.fpdf.org/en/script/script76.php" rel="nofollow noreferrer"><strong>FPDF2File</strong></a> that are usually displayed in the browser window.</p>
  
  <p>Notice:</p>
  
  <ul>
  <li>The parameters are passed to the PHP that generates report POST.</li>
  <li>The file is being accessed exclusively via HTTPS with a valid certificate.</li>
  <li>The web server is able to log all errors and errors are being properly recorded in the log, but no error related to that FPDF/PHP is being recorded. (Ie I clean the error log, run the report and no error appears in the log ... forcing a mistake on purpose and it is registered). Thus, it seems that there is no syntax error.</li>
  <li>The Content-type used is: header ( 'Content-type: application / pdf');
  The problem occurs in Windows computers with Google Chrome (tested on multiple machines).</li>
  <li>All buttons of the PDF rendering plug-in browsers (save, print, rotate, zoom, etc.) work normally. Except the save button in Google Chrome (in other browsers work normal).</li>
  </ul>
  
  <p>When trying to save the PDF already opened and displayed on Google Chrome, the following error occurs:</p>
  
  <blockquote>
    <p>Failure - Network error</p>
  </blockquote>
  
  <p>Therefore, you can not save the PDF, unless you go to print and print in PDF, or print the PDF PDF, which does not make much sense.</p>
  
  <p><strong>Could someone tell how to solve this error?</strong></p>
  
  <p>Thanks a lot!</p>
