Since this update we have had numerous calls regarding printing from our web app. Our web app uses an iframe and we use css @media print to hide all but this iframe for printing purposes. Since the update the user receives an Error 404--Not Found instead of the actual page. It would seem from the network trace that IE creates a temp .htm file in the local directory like D3CD911.htm, it then downloads css/js resources and then finally it makes this call /D3CD911.htm. This is making a call to www.mywebsite.co.uk/D3CD911.htm. This obviously does not exist on the website so the 404 is returned.
I struggling to find a pattern to the problem and it doesn't seem to be affecting other public sites.
Any guidance would be much appreciated.
