.htaccess Force PDF Download in Safari

I want to force a PDF to download, rather than load in-browser.

I'm using the following code in my .htaccess:

<FilesMatch "\.(?i:pdf)$">
  ForceTyp开发者_开发知识库e application/octet-stream
  Header set Content-Disposition attachment
</FilesMatch>

It works great, except in Safari.

Any ideas?

Try this in your .htaccess file

SetEnvIf Request_URI "\.pdf$" requested_pdf=pdf
Header add Content-Disposition "attachment" env=requested_pdf

It appears to work fine even with safari on my tests here
