0001581: Gzip filter breaks IE caching
The GZip filter sets Vary: Encoding on all requests, even if it does not decide to compress it. In MSIE (up to and include 6.0), if you use Vary with anything but user-agent, it will not cache locally. It ignores cache-control, expires, etag, everything and will simply request the same URL each time.

Obviously having to download every single image, CSS, and js file far exceeds any potential benefit from compressing the text content.
