Attempt to review the proxy patch...

      Revert r219061 to properly test this patch, as r219061 masks the

      underlying bug (although it is a -good- patch in and of itself).

       +1: wrowe, jim

       -1: jorton: this is a massive patch and extremely hard to review

           for actual interesting content; it is mixed in with all sorts

           of unrelated stuff.  It needs to at least be split up or

           the unrelated stuff removed.

           unrelated change: s/apr_strnatcasecmp/strcasecmp/

           unrelated change: s/b/bb/ on variable+parameter names a few times

           unrelated change: whitespaces changes all over the shop

           spurious change:? send_request_body() appears to have been inlined

           unrelated change: Via header handling

         trawick noted on list: we elected C-L not for efficiency, but because

                 it's the most widely supported [paraphrasing]
