  • Download the file
  • Change content of the PDF/ODT file

Hello Mozira,
Is there a public link for us to validate? Thanks.

Flags: needinfo?(

For the moment no, because on my server noone (except me) can modify PDF files.

  • Create blank page with only one link to PDF (index.html) <a href="any.pdf">Click</a>
  • Add in .htaccess header "Cache-Control: public, max-age=864000" for all PDFs
  • Put on server any.pdf
  • modify PDF on server, use Ctrl+F5 in browser and click the link (perform several times this action).

It is very easy after installation of EasyPHP on local computer (the domain can be - the bug is also present).

From comment 2, the page you hard refreshed is the page with link, not the download file.

How to "refresh" download files? Another shortcut or should be refresh (removed from cache) all domain files?

This following SUMO link is the solution to the best of my knowledge.

Thanks for reporting this.
