It sounds like it's the SVG plugin you're using on IE that's badly
misbehaving. That said, I've not seen any plugins that correctly pass
across the full headers that the browser would. I tried using sessions
once to secure media files by checking for a valid login against the
session id, but the plugins requesting the video clips didn't send any
cookie data in the header request. As such, it might be better to not
rely on it in this case.
