"Access is Denied" when embedding file from blob URL in IE
I think the answer is "no". Our site generates PDF on the fly but we sniff the browser for what can be done with the returned PDF.

If you are on Chrome you could select the "Embed PDF" here and it works like a charm ... if you are on IE, even if you select "Embed", it downloads the file. Because IE cannot and we just reroute anyone on IE to the download code.

And don't get us started on what else is wrong on IE, several of the pages just broke because IE stopped serializing end tags for some "p" tags in the document.
