 cache ignores Vary response headers

           Summary:  cache ignores Vary response headers
           Product: Apache httpd-2.0
           Version: HEAD
          Platform: All
               URL: http://coad.measurement-factory.com/cgi-

                    c2616/varyMismatch
        OS/Version: All
            Status: NEW
          Severity: Major
          Priority: Other
         Component: mod_cache

        ReportedBy: coad@measurement-factory.com


Looks like a possible RFC 2616 MUST violation.
Vary response header does not cause invalidation
when 2nd request headers mismatch original request
headers. This is a pretty nasty bug since Vary is often
used for server-driven negotiation.

See attached traces for details and ways to reproduce
some of the violations mentioned above.

Test case IDs in the trace link to human-oriented test case
description and RFC quotes, if available.
