CHANGES

      for back-compatibility with rst's own AI-lab servers.

      All of these modules were substantially complete, and functional 
      or nearly so (a few, which implemented features not in use at
      Thau's site, required patches of a few lines).

   *) sub-request machinery, to allow modules to determine how other
      modules would assign MIME types to a given file, or optionally
      serve its content (this is heavily used by mod_dir, mod_include
      and mod_negotiation).

   *) Resource pool system for keeping track of memory allocated and
      files opened in service of a particular request.  Much of the
      code in the modules (when they weren't rewrites) was adjusted to 
      replace a pervasive convention of using fixed-size buffers on
      the stack with an equally pervasive convention of using memory
      allocated with palloc().

   *) Reorganization of data structures associated with a given
      request to eliminate use of global variables and the troublesome 
      unmunge_name function (used in NCSA and early Apache releases to 
      attempt to determine the URI which mapped to a given filename
      --- a difficult proposition, given that it is easy to produce
      setups in which multiple URIs map to the same file).

   *) Source files renamed and rearranged

   *) Very simple pre-forking behavior --- parent process forked off a 
      fixed number of children, and then just waited for SIGHUP.

   *) Other more minor changes too numerous to list.

   This release included modified versions of a lot of code from the
   Apache 0.6.4 public release, plus an early pre-forking patch
   codeveloped by Robert Thau and Rob Hartill.

Changes with Apache 0.7.3                                        20 Jun 1995

   *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
      were incorporated by Rob Hartill on the main branch while Robert Thau
      worked on the Shambhala rewrite above.  Most were merged into the
      Shambala architecture after Apache 0.8.0.

Changes with Apache 0.6.4                                        13 May 1995

   *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
      and others.

Changes with Apache 0.5.1                                        10 Apr 1995

Changes with Apache 0.4                                          02 Apr 1995

  *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
     and Rob Hartill.

Changes with Apache 0.3                                          24 Mar 1995

  *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
     Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
     Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
