There is some configuration in abyss to download pdf files instead of opening them???
This is not a Web server issue. But you can force downloading a PDF by outputting some special HTTP headers:
Content-type: application/pdf
Content-disposition: attachment; filename="file.pdf"
You could output these using a script or even declare these two as custom HTTP headers for virtual path *.pdf (see
