MIME type wont change for IIS6 Dynamic content

After changing .zip file mime type on IIS 6 metabase to application/x-zip, I can see that .zip downloads with a new content type when I download it from a static folder (/zip).

But I use an ISAPI extension to download .zip files:

http://example.com/?downloadname=filename

Which changes it to application/x-zip-compressed.

I have verified it with fiddler and httpanalyzer. A global or targeted mime type change doesn't work.

Any ideas on how to force the mime type change on dynamically generated content such as this?

You should set the mime type from within the ISAP extension by sending the header Content-Type: application/x-zip-compressed. How to send that header depends a little bit on the language / framework you used to create the ISAPI extension.
