mod_proxy overwrites Date header

           Summary: mod_proxy overwrites Date header
           Product: Apache httpd-2.0
           Version: 2.0.43
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: mod_proxy
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: apache-bugs@wotevah.com


It appears that mod_proxy overwrites the Date header with the local date.
Mine is configured as a Reverse Proxy (have not tried the other way).
The date header is in the proper format (comes from an Apache 1.3 server).

This should not happen because this way the client loses the reference for
the Expires header (which passes through unmodified).

Below are two sets of response headers I tested with. The first one is
the backend server accessed directly, the second is via the proxy, at
about 20 seconds time difference. The time on the proxy is 2-3 minutes
behind the backend's. The frontend always sets the expiration date to 
same value as date.
