Acrobat Reader successfully renders sample1.pdf inside IE given the following HTML:
<embed style="width: 8.5in; height: 11in;" id="pdfViewer" src="sample1.pdf" type="application/pdf">
What javascript allows me to use that same PDF reader instance to display sample2.pdf?
EDIT: I don't care what HTML is involved, I don't think -- the goal is to use IE to load/render the reader instance once to show many PDF files as the user selects them.
