IE 6 on Win2K generates non RFC Host: header on redirect

On Win2K systems IE Version 6.0.2800.1106 with all Windows Update patches
applied generates a non RFC2616 (Http 1.1) compliant host header when
following a redirect. Specifically if the redirect is to an address
specifying a port number, the Host header does not include the required port
number.
Example HTTP Session trace extrated from network sniffing:

The second response contains garbage which is a consequence of the garbage
in (GIGO).
The source of the garbage input is IE on the Win2K platform not correctly
generating the Host: HTTP header.
The latest version of IE on other platforms (i.e. WinXP running IE Version:
6.0.2900.2180.xpsp_sp2_gdr.050301-1519) correctly follows Redirects and
generates an RFC2616 compliant Host: header containing the port number when
appropriate.
Does anyone know when this bug will be fixed for IE6 on Win2K?
Thanks.
