     PR 54420 [Tianyin Xu <tixu cs ucsd edu>]

  *) mod_cache: Make option "CacheDisable" in mod_cache case insensitive.
     PR 54462 [Tianyin Xu <tixu cs ucsd edu>]
  *) mod_cache: If a 304 response indicates an entity not currently cached, then
     the cache MUST disregard the response and repeat the request without the
     conditional. [Graham Leggett, Co-Advisor <coad measurement-factory.com>]

  *) mod_cache: Ensure that we don't attempt to replace a cached response
     with an older response as per RFC2616 13.12. [Graham Leggett, Co-Advisor
     <coad measurement-factory.com>]

  *) core, mod_cache: Ensure RFC2616 compliance in ap_meets_conditions()
     with weak validation combined with If-Range and Range headers. Break
     out explicit conditional header checks to be useable elsewhere in the
     server. Ensure weak validation RFC compliance in the byteranges filter.
     Ensure RFC validation compliance when serving cached entities. PR 16142
     [Graham Leggett, Co-Advisor <coad measurement-factory.com>]

  *) core: Add the ability to do explicit matching on weak and strong ETags
     as per RFC2616 Section 13.3.3. [Graham Leggett, Co-Advisor
     <coad measurement-factory.com>]

  *) mod_cache: Ensure that updated responses to HEAD requests don't get

     Not Modified response are caught and cause the entity to be removed.

  *) mod_cache: Make sure Vary processing handles multivalued Vary headers and
     multivalued headers referred to via Vary. [Graham Leggett]

  *) mod_cache: When serving from cache, only the last header of a multivalued
     header was taken into account. Fixed. Ensure that Warning headers are
     correctly handled as per RFC2616. [Graham Leggett]

  *) mod_cache: Ignore response headers specified by no-cache=header and
     private=header as specified by RFC2616 14.9.1 What is Cacheable. Ensure
     that these headers are still processed when multiple Cache-Control
     headers are present in the response. PR 54706 [Graham Leggett,
     Yann Ylavic <ylavic.dev gmail.com>]

     namespace httpd segfaults. PR 52559 [Diego Santa Cruz
     <diego.santaCruz spinetix.com>]

     we compare unencoded paths. PR 53910 [Timothy Wood <tjw omnigroup.com>]

     the common case. [Christophe Jaillet]
