Changes with Apache 2.1.0-dev

  [Remove entries to the current 2.0 section below, when backported]
  *) initialize server arrays prior to calling ap_setup_prelinked_modules
     so that static modules can push Defines values when registering
     hooks just like DSO modules can ["Philippe M. Chiasson" <gozer cpan.org>]

  *) Add -l option to rotatelogs to let it use local time rather than
     UTC.  PR 24417.  [Ken Coar, Uli Zappe <uli ritual.org>]

  *) Drop the ErrorHeader directive which turned out to be a misnomer.
     Instead there's a new optional flag for the Header directive
     ('always'), which keeps the former ErrorHeader functionality.
     [André Malo]

  *) mod_deflate: Don't deflate responses with zero length 
     e.g. proxied 304's [Allan Edwards]

  *) <IfModule> now recognizes the module identifier in addition to the
     file name. PR 29003.  [Edward Rudd <eddie omegaware.com>, André Malo]

  *) mod_ssl: Add "SSLUserName" directive to set r->user based on a
     chosen SSL environment variable.  PR 20957. 
     [Martin v. Loewis <martin v.loewis.de>]

  *) mod_ssl: Add "SSLHonorCipherOrder" directive to enable the
     OpenSSL 0.9.7 flag which uses the server's cipher order rather
     than the client's.  PR 28665.
     [Jim Schneider <jschneid netilla.com>]
  *) mod_ssl: Drop support for the CompatEnvVars argument to
     SSLOptions, which was never actually implemented in 2.0.
     [Joe Orton]

  *) Fix bug in mod_deflate that unconditionally sent deflate'd output
     even when Accept-Encoding is not present.  [Justin Erenkrantz]

  *) Pass environment variables through to piped loggers, resolving
     a regression since 1.3.  [Ken Coar, Jeff Trawick]

  *) Enable the option to support anonymous shared memory in mod_ldap.
     This makes the cache work on Linux again. [Graham Leggett]

  *) Small fix to allow reverse proxying to an ftp server. Previously
     an attempt to do this would try and connect to 0.0.0.0, regardless
     of the server specified. PR 24922
     [Pascal Terjan <pterjan@linuxfr.org>]

  *) RPM spec file changes: changed default dependancy to link to db4
     instead of db3. Fixed complaints about unpackaged files.
     [Graham Leggett]

  *) External rewrite map responses are no longer limited to 2048
     bytes.  [André Malo]

  *) Proxy server was deleting cookies that Apache had already
     assigned if the origin server had set any cookies. PR 27023.
     [Jim Jagielski]

  *) Prevent Win32 pool corruption at startup [Allan Edwards]

  *) Removed old and unmaintained ap_add_named_module API and changed
     the following APIs to return an error instead of hard exiting:
     ap_add_module, ap_add_loaded_module, ap_setup_prelinked_modules,
     and ap_process_resource_config.  [André Malo]
  *) Include directives no longer refuse to process symlinks on
     directories. Instead there's now a maximum nesting level
     of included directories (128 as distributed). This is configurable
     at compile time using the -DAP_MAX_INCLUDE_DIR_DEPTH switch.
     PR 28492.  [André Malo]

  *) Recursive Include directives no longer crash. The server stops
     including configuration files after a certain nesting level (128
     as distributed). This is configurable at compile time using the
     -DAP_MAX_INCLUDE_DEPTH switch. PR 28370.  [André Malo]

  *) mod_headers: Allow %% in header values to represent a literal %.
     [André Malo]

  *) mod_headers: Allow env clauses also for 'echo' and 'unset' actions.
     [André Malo]

  *) mod_headers: Allow 'echo' also for ErrorHeaders.  [André Malo]

  *) mod_cgi: Handle output on stderr during script execution on Unix
     platforms; preventing deadlock when stderr output fills pipe buffer.

     Also fixes case where stderr from nph- scripts could be lost.
     PR 22030, 18348.  [Joe Orton, Jeff Trawick]

Ian Holsman committed
  *) mod_deflate: New option for DEFLATE output file (force-gzip),
     new output filter 'INFLATE' for uncompressing responses.
     [Nick Kew <Nick at WebThing dot com>, Ian Holsman]

  *) Added new module mod_version, which provides version dependent
     configuration containers.  [André Malo]

  *) Accept URLs for the ServerAdmin directive. If the supplied
     argument is not recognized as an URL, assume it's a mail address.
     PR 28174.  [André Malo]

  *) mod_rewrite no longer confuses the RewriteMap caches if
     different maps defined in different virtual hosts use the
     same map name. PR 26462.  [André Malo]

  *) mod_log_config now logs all Set-Cookie headers if the %{Set-Cookie}o
     format is used.  PR 27787.  [André Malo]

  *) mod_usertrack: Escape the cookie name before pasting into the
     regexp.  [André Malo]

  *) Enable special ErrorDocument value 'default' which restores the
     canned server response for the scope of the directive.
     [Geoffrey Young]

  *) Allow Digest providers to return AUTH_DENIED to propagate a 401
     status and terminate the provider chain prior to checking the password.
     [Geoffrey Young]

  *) mod_rewrite now officially supports RewriteRules in <Proxy> sections.
     PR 27985.  [André Malo]

  *) mod_cgid: Don't allow Scriptsock to be specified inside VirtualHost;
     Don't place script socket inside default server root instead of
     actual server root.  PR 27886.  [Jeff Trawick]

  *) work around MSIE Digest auth bug - if AuthDigestEnableQueryStringHack
     is set in r->subprocess_env allow mismatched query strings to pass.
     PR 27758.  [Paul Querna <chip force-elite.com>, Geoffrey Young]

  *) Satisfy directives now can be influenced by a surrounding <Limit>
     container.  PR 14726.  [André Malo]

  *) mod_proxy: Fix handling of non-200 success status codes when
     "ProxyErrorOverride On" is configured.  PR 20183.
     [Marcus Janson <marcus.janson tre.se>, Joe Orton]

  *) Threaded MPMs for Unix and Win32: Add support for ThreadStackSize 
     directive (previously NetWare-only) to override default thread 
     stack size for threads which handle client connections.  Required 
     for some third-party modules on platforms with small default 
     thread stack size.  [Jeff Trawick]
  *) mod_rewrite: Support for recognizing SSL variables in RewriteCond
     using the new "SSL:" format.  [Joe Orton, Madhusudan Mathihalli]

  *) mod_setenvif: Remove "support" for Remote_User variable which
     never worked at all. PR 25725.  [André Malo]

  *) minor mod_auth_basic and mod_auth_digest sync.  mod_auth_basic
     now populates r->user with the (possibly unauthenticated) user,
     and mod_auth_digest returns 500 when a provider returns
     AUTH_GENERAL_ERROR.
     [Geoffrey Young]

  *) The whole codebase was relicensed and is now available under
     the Apache License, Version 2.0 (http://www.apache.org/licenses).
     [Apache Software Foundation]

  *) FreeBSD: Use the httpready accept filter instead of dataready on
     newer levels of the OS.  [Paul Querna <chip force-elite.com>]

  *) Delete some make-generated files in the server directory during 
     "make clean" processing.  PR 26552.  [Jeff Trawick]

  *) Add core version query function (ap_get_server_revision) and
     accompanying ap_version_t structure (minor MMN bump).
     [André Malo]

  *) mod_rewrite: EOLs sent by external rewritemaps are now consumed
     as whole. That way, on systems with more than one EOL character
     rewritemap programs no longer need to switch stdout to binary
     mode. PR 25635.  [André Malo]

  *) mod_rewrite: Introduce the ability to force a content handler via
     the [handler=...] flag.  [André Malo]

  *) mod_rewrite: Introduce the RewriteCond -x check, which returns
     true if the pattern is a file with execution permissions.
     [André Malo]

  *) Allow proxying of resources that are invoked via DirectoryIndex.
     PR 14648.  [André Malo]

  *) mod_rewrite: Allow proxying and RewriteRules in directory context
     for subrequests.  PR 14648, 15114.  [André Malo]

  *) mod_rewrite: Allow setting of any valid HTTP response code.
     PR 25917.  [André Malo]

  *) mod_rewrite: Cookie creation now works locale independent.
     [André Malo]

  *) mod_ssl: Add support for distributed session cache using 'distcache'.
     [Geoff Thorpe <geoff geoffthorpe.net>]

  *) mod_dav: Disallow requests with an unescaped hash character in
