this is by design. when IE downloads a content type that it uses external
viewer such as pdf, it does the following:
1) detects content type requires external viewer
2) re-requests the content with a special header to verify the content-type
3) loads the external viewier
4) passes the url to the viewer so the viewer can download the content
of course if you have anonymous turned off, there are a few more trips for
authenication.
