Fixes are available

APAR status

Closed as program error.

Error description

An application that does its own caching may attach special
significance (over and above HTTP semantics) to the Date header.
Such an application would want full control of the Date header
being relayed to the client.

*                  "Date" header.                              *

* PROBLEM DESCRIPTION: IBM HTTP Server always supplies its own *
*                      HTTP "Date" header to responses         *
*                      generated                               *
*                      by the WebSphere Plugin.                *
****************************************************************
* RECOMMENDATION:  Apply this fix and custom property if an    *
*                  application-specific requirement conflicts  *
*                  with                                        *
*                  the default handling of Date headers.       *
****************************************************************
IBM HTTP Server (IHS) supplies its own HTTP "Date" header, even
when the WebSphere Application Server WebServer Plug-in is
forwarding a HTTP response that already contains a Date
header.  An argument can be made either way for the proper
behavior for IHS in this case as a non-transparent proxy.
Some applications might apply special significance to this
header when it returns in a subsequent If-Modified-Since, and
expect it to only match values they've generated based on for
example, file-based assets.

Problem conclusion

A new directive was added to IHS named 'PreserveDateHeader'. Whe
set to the value ON, IHS will not replace the Date header set by
the handler (WAS Plug-in, mod_cgid, etc) with its own Date heade

The fix for this APAR is expected to be included in the followin
IBM HTTP Server fixpacks:
 - 8.5.5.6
 - 8.0.0.11
