You seem to be on the right path, considering the next paragraph.

Not saying that there may not be a problem in the isap_redirector, but in the answers 
above, I see a header

Are you sure that it is not IIS which is sending back these responses ?

Since you are talking about static pages and images, it may be that these are sent back 
directly by IIS, and never forwarded to Tomcat.

It may be useful to see the URLs which you are using in your requests, and the mappings 
which you do to the isapi_redirector and Tomcat, to verify this.
(I believe that with the isapi_redirector, those mappings are in a file named 
"uriworkermap" or similar).
