I have been working like mad with PDFs built dynamically with PHP the last week.
One thing to be *absolutely* sure of is that you do not have ANY
output before the PDF download starts.
If you have Apache2 with mod_header loaded, there is a FilesMatch
directive to always force a download for a PDF
<FilesMatch "\.(?i:pdf)$">
ForceType application/octet-stream
Header set Content-Disposition attachment
</FilesMatch>
On a side note, you do not need AJAX for this feature to feed the user
a PDF file for download just set the form action to empty (same page)
and it should leave the page/browser right where it is with the form
still filled out, unless you are trying to feed a PDF to a div... you
aren't are you?
by the by which PDF library did you use to generate with?
