Public bug reported:

Ubuntu 14.04LTS x86_64

In apache 2.4.7 there is a bug in mod_dir, in that it does not stop when
the URL has just been rewritten by mod_rewrite.

If you have rewrite rules in .htaccess, ending in a [P] for an external
URL, rule execution should stop and mod_proxy should go and fetch the
given URL. Instead, mod_dir fires another round of rewrite rule checks
as it looks for .../index.html, possibly giving completely different
results (e.g. not fetching from remote site).

  ...
  *) mod_dir: Don't search for a DirectoryIndex or DirectorySlash on a
     URL that was just rewritten by mod_rewrite. PR53929. [Eric Covener]
