I've created an example page to try:

I don't really know WHAT it is. :) It is a "behavior" in IE. Here it is:
http://msdn.microsoft.com/library/default.asp?url=/workshop/author/behaviors/reference/behaviors/download.asp
"download Behavior - Downloads a file and notifies a specified callback
function when the download is complete."

It has the exact same User-agent as the normal browser from the
access_logs; perhaps it "bypasses" MSIE's content-decoding layer and does a
request directly, then fails on the binary data...

The startDownload method has a function reference as the 2nd argument. If
everything goes as planned, that javascript function is called with as a
single argument the returned HTTP response (it is intended for text only, I
believe) in a string.

This function call does not happen in one of the four examples on
readme.html in the mentioned two MSIE versions using HTTP/1.1 and no proxy.

Hope this clears something up, it might still be user error on my part
ofcourse, but I've seen it reported by two users on various sites using the
download behavior, the day after I started using mod_gzip for encoding the
results.

Any insight would be appreciated :)
Thanks,
walter.
