Cfml to control URL

I was hoping there is some cfml method of controlling a URL that points to a PDF file.
So the URL will pop up naturally asking you to save the PDF.
I was hoping to script a way of saving this to a server location silently, then emailing it in a cfm page.

i am able to grab the pdf with the code below. However it still pops up asking one to save or open…

is there a way of doing this silently without the user intervention.
