We have a navigation system that caches already viewed pages and navigates back to them if they are in the page store.
Now one of this pages is an HTMLPAGEHOLDER
And upon initial construction of the page we set the place holder as such..
Placeholder.SourceUrl = new Uri(Uri);
if the uri is directed say towards some random html page. All Works as expected.
However if the html page loads a PDF OR the uri is directed straight to the PDF file on the server,
It loads the PDF initially but when one navigates away and comes back to that page the place holder is empty.
Is there a Known issue with reusing PDF??
One of the reason we are caching this is beacuse we don't want to loose the the users scroll view when they are navigating through our pages.
By the way this issue is only in IE, I have IE 8 Installed
