**Question**

Is it possible to view a PDF through an iframe that is stored in a SharePoint 2010 document library? If so, what changes do I need to make to the default document library settings?

**Background**

I want to display a PDF that is stored in a document library through an iframe. Currently this works without any issues when the PDF is stored in a _layouts sub-folder. When I store it in a document library I'm only given the option to save it locally. Below is the test HTML I used to validate this.



    <html>
    <body>
        Document Library: Forces user to download the document
    	<iframe height="300" width="300" 
    		src="http://sprocks/Shared%20Documents/test01.pdf" />
    
        _layouts sub-folder: Renders as expected in the iframe
    	<iframe height="300" width="300" 
    		src="http://sprocks/_layouts/CachedReports/test01.pdf" />
    </body>
    </html>
