Modified the cache code to be header-location agnostic. Also
  fixed a number of other cache code bugs related to PR 15852.
  Includes a patch submitted by Sushma Rai <rsushma@novell.com>.
  This fixes mod_mem_cache but not mod_disk_cache yet so I'm not
  closing the PR since that is what they are using. [Paul J. Reder]
