Unfortunately, it is still subject to page caching. However, you can see an example of what I have been able to do here.
So, ICO and PDF files won't display so I removed them from the list of extensions. I don't know whether or not ODG and ODI files will display. There aren't any on this wiki for me to test with. Also, if you have any additional formats enabled on your wiki, you would need to add their extensions to the list.
