directory, ala /etc/rc.d/init. Basically, if any of the
config "files" are actually directories, all files in
that directory (and in subdirectories) will be parsed as
config files. Thus you can add new config directives with
no file edits at all, simply file additions.

  Updating the MPE DSO code to be compatible with an OS patch fixing an
  earlier DSO problem.

  Refining how MPE deals with UID/GID management and dealing with some MPE
  limitations in this area.

  First-time support for mod_proxy.

  #include tweakage required for using apxs to build modules without access
  to the full source tree.

  Other minor tweaks.

security bug in some mass virtual hosting configurations
that can allow a remote attacker to retrieve some files
on the system that should be inaccessible. The problem
occured with requests including the line "Host: ..." --
the last dot is stripped and the remaining ".." then
reveals a parent directory.

  Based on Brian's and my observations, the <Directory '/'> default root
  patch should now be complete for WIN32, OS2 and NETWARE.
  Still some disagreement if '/' is canonical for Win32/OS2, but we will
  thrash that out.

  Backing out one piece of the prior change.  I'm not satisfied with
  lowercasing the non-filespec portion of the canonical name
  (//server/share/ will still be lowercased.)  This introduced more
  potential problems than it solved.

If the result of a RewriteRule is a filename that contains expansion
specifiers, especially regexp backreferences $0..$9 and %0..%9, then it
may be possible for an attacker to access any file on the web server.
The fix replaces a multi-pass string expander with a one-pass expander.

  Fix the test to walk through directory blocks '/', '//', '//machine', and
  '//machine/share', without trying to touch the .htaccess file in the
  unsafe cases.  This allows <Directory /> to match d:/, or <Directory //>
  to match the UNC path of any network drive.

  Fix util_win32 to accept '/', '//', '//machine/', and '//machine/share/'
  for url parsing in order to accept those <Directory > blocks.

  Big warning: remove the assumption that *~* is the alias name, and always
  walk the tree for aliasing.  This test is flawed, because NT can be, and
  Novell always follows different conventions.  It is only safe to always
  test, but the old test remains with a scary symbol to include it.

  There is some other optimization available, to perhaps flag that the url
  has already been walked/translated, but that isn't incorporated [yet].
