read the pdf

I'd like to load a PDF file into a page, in my controller:

send_file "/path to/my.pdf", :disposition => "inline"

However, instead of rendering inline, it asks to download the file.

How can I display the contents without downloading? using ruby on rails

Are you sending the correct MIME type in your response?

Assuming you are and you're getting the same result, then Im assuming your browser doesn't know what to do with PDF files (either it doesn't have any PDF plugins or is configured incorrectly for PDF files).
