Daniel,

I had a similar problem with this version of Apache (2.0.46), but did
not test with later versions.
I did not find any solution at that time and revert to Apache 1.3.
Note that 2 bugs related to this issue are referenced on Bugzilla :
11427 (http://nagoya.apache.org/bugzilla/show_bug.cgi?id=11427) and
(more recent) 23567
(http://nagoya.apache.org/bugzilla/show_bug.cgi?id=23567).
You may append informations to these pages, and possibly provide a test
case to help the Apache team reproduce and correct the bug if any.

Hope that helps,
Chris.
