Changes with Apache 2.1.2
*) mod_proxy: Respect errors reported by pre_connection hooks.
[Jeff Trawick]
*) core: Error out on sections that are missing an argument instead of
silently consuming the section. PR 25460.
[Geoffrey Young, Paul Querna]
*) mod_cache/mod_mem_cache/mod_disk_cache: Move out of experimental.
*) Upgraded PCRE to version 5.0. [Brian Pane]
*) mod_cgid: Catch configuration problem where two web server instances
share same ServerRoot but admin forgot to use ScriptSock.
[Jeff Trawick]
*) mod_cgi: Ensure that all stderr is logged for a script which returns
a Location header to generate a non-local redirect. PR 20111.
[Joe Orton]
*) Added the Event MPM to more efficiently handle clients during a
Keep Alive request.
[Paul Querna, Greg Ames]
Changes with Apache 2.1.1
*) mod_proxy_http: Stream content better - always flush buffered data to
the client before blocking waiting for new data. PR 19954.
[Joe Orton]
*) mod_ssl: Add support for command-line option "-t -DDUMP_CERTS" which
will dump the filenames of all configured SSL certificates to stdout.
[Joe Orton]
*) mod_disk_cache: Remove a bunch of non-implemented garbage collection
and cache size directives that are now available through htcacheclean.
[Justin Erenkrantz]
*) Add htcacheclean to support/ for assistance with mod_disk_cache.
[Andreas Steinmetz]
*) mod_authnz_ldap: Added the directive "Requires ldap-filter" that
allows the module to authorize a user based on a complex LDAP
search filter. [Brad Nicholes]
*) mod_usertrack: Run the fixups hook before other modules.
PR 29755. [Paul Querna]
*) Allow mod_authnz_ldap authorization functionality to be used
without requiring the user to also be authenticated through
mod_authnz_ldap. This allows other authentication modules to
take advantage of LDAP authorization only [PR 28253]
[Jari Ahonen jah progress.com, Brad Nicholes]
*) Log the client IP address when an error occurs disabling nagle on a
connection, but log at a severity of debug since this error
generally means that the connection was dropped before data was
sent. Log the client IP address when reporting errors in the core
output filter. [Jeff Trawick]
*) core: Add a warning message if the request line read fails.
[Paul Querna]
*) mod_rewrite: Removed the MaxRedirects option in favor of the
core LimitInternalRecursion directive. [André Malo]
*) mod_info: Added listing of the Request Hooks and added more build
information like 'httpd -V' contains. Changed output to XHTML.

headers, pass that to the proxy. [Justin Erenkrantz]
*) Recognize QSA flag in mod_rewrite again.
[Jan Kratochvil <rcpt-dev.AT.httpd.apache.org jankratochvil.net>]
*) Restructured mod_auth_ldap to fit the new authentication model.
The module is now called authnz_ldap and has been moved out of
the modules/experimental area and into modules/aaa with the other
auth modules. Both the authn_ldap provider and the authz_ldap
handler are contained within the authnz_ldap module. The
authz_ldap handler introduces 3 new "requires" values for handling
authorization. These handlers are ldap-user, ldap-group and
ldap-dn. [Brad Nicholes]
*) Fix some compiler warnings in proxy
[Geoffrey Young <geoff@modperlcookbook.org>]

[Joe Orton]
*) Improve error handling for corrupted pid files. [Jeff Trawick]
*) mod_proxy.c and proxy_util.c: Enable compiling on 2.0-HEAD
(for backwards compatibility):
Avoids mod_ssl.h (not included in 2.0-HEAD) and
use apr_socket_create_ex for 0.9.x
[Mladen Turk]
*) Added proxy_ajp.c module for proxy support to ajp:// backends.
[Jean Frederic Clere]
*) Fixes the build of proxy on Windows. Since the proxy_module is declared
as extern using AP_MODULE_DECLARE_DATA that expands to dllexport, there
is a LNK2001 error when building proxy_http. [Mladen Turk]
*) Remove LDAP toolkit specific code from util_ldap and mod_auth_ldap.
[Graham Leggett]
*) Remove deprecated/removed APR_STATUS_IS_SUCCESS(). [Justin Erenkrantz]
*) perchild MPM: Fix thread safety problem in the use of longjmp().
[Tsuyoshi SASAMOTO <nazonazo super.win.ne.jp>]

load balancing support in mod_proxy. [Mladen Turk]
*) mod_nw_ssl: Added the directive NWSSLUpgradeable to mod_nw_ssl to
allow a non-secure connection to be upgraded to secure connections
[Brad Nicholes]
*) core: Add Options= syntax to AllowOverride to specify which options
may be overridden in .htaccess files. PR 29310.
[Tom Alsberg <alsbergt cs.huji.ac.il>, Paul Querna]
*) ab: Handle long URLs with an error instead of an buffer overflow.
PR 28204. [Erik Weide <erik.weidel mplus-technologies.de>, Paul Querna]
*) mod_so, core: Add new command line options to print all loaded
modules. '-t -D DUMP_MODULES' and '-M' will show all static
and shared modules as loaded from the configuration file.
[Paul Querna]
*) mod_autoindex: Add ShowForbidden to IndexOptions to list files
that are not shown because the subrequest returned 401 or 403.
PR 10575. [Paul Querna]
*) mod_headers: implement "Early" processing option in post_read_request
to enable Header and RequestHeader directives to be used to set up
testcases for pre-fixups request phases [Nick Kew]
*) mod_proxy: multiple bugfixes, principally support cookies in
ProxyPassReverse, and don't canonicalise URL passed to backend.
Documentation correspondingly updated. [Nick Kew <nick webthing.com>]
*) mod_deflate: support gzip flags in inflate_out_filter
[Nick Kew <nick webthing.com>]
*) 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 "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 and start
them via the shell, resolving regressions since 1.3. PR 28815
[Ken Coar, Jeff Trawick]
*) 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]
*) 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]
*) 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_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]
*) mod_log_config now logs all Set-Cookie headers if the %{Set-Cookie}o
format is used. PR 27787. [André Malo]
*) 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_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]
*) 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]

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]
*) 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]

"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]
*) 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
the Request-URI. PR 21779. [Amit Athavale <amit_athavale lycos.com>]
*) mod_proxy with ProxyErrorOverride On in a reverse-proxy configuration
attaches a body to the 302 response and a wrong Content-Length header.
PR: 22951 [Ermanno Scaglione scaglione ..at.. starnetone.de]
*) Bring ErrorHeader concept forward from 1.3, so that response
header fields can be set for return even on errors or external
redirects. [Ken Coar]
*) Fix <Limit> and <LimitExcept> parsing to require a closing '>'
in the initial container. PR 25414.
[Geoffrey Young <geoff apache.org>]

directory, display the MPM name and some MPM properties.
[Geoffrey Young <geoff apache.org>]

[Tyler Riddle <triddle_1999 yahoo.com>, Paul Querna <chip force-elite.com>]
*) Fix uninitialized gprof directory name in prefork MPM. PR 24450.
[Chris Knight <Christopher.D.Knight nasa.gov>]
*) Log an error when requests for URIs which fail to map to a valid
filesystem name are rejected with 403. [Jeff Trawick]
*) Switch to APR 1.0 API.
*) Major overhaul of mod_include's filter parser. The new parser code
is expected to be more robust and should catch all of the edge cases
that were not handled by the previous one. This includes a binary
incompatible change of mod_include's external API. [André Malo]
*) mod_rewrite: Allow forced mimetypes [T=...] to get expanded.
PR 14223. [André Malo]
*) mod_rewrite: Fix LA-U and LA-F lookups in directory context. Previously
the current rewrite state was just used as lookup path, which lead to
strange and often useless results. Related to PR 8493. [André Malo]
*) Change Listen directive to bind to all addresses when a hostname is
not specified. [Justin Erenkrantz]
*) Correct failure with Listen directives on machines with IPv6 enabled.
[Colm MacCárthaigh <colm stdlib.net>, Justin Erenkrantz]
*) Fix a link failure in mod_ssl when the OpenSSL libraries contain
the ENGINE functions but the engine header files are missing.
[Cliff Woolley]
*) mod_rewrite: RewriteRules in server context using the force
type feature [T=...] no longer disable MultiViews. [André Malo]
*) mod_rewrite: Allow piped rewrite logs to be relative to ServerRoot.
[André Malo]
*) mod_authz_groupfile: Strip trailing spaces of group names. This
hopefully saves some hours of searching for typos. PR 12863.
[André Malo]
*) mod_actions: Propagate the handler name to the action script via
the REDIRECT_HANDLER environment variable. [André Malo]
*) mod_actions: Introduce the "virtual" modifier to the Action directive,
which allows the use of handlers for virtual locations. PR 8431.
[André Malo]
*) mod_speling: Recognize AcceptPathInfo setting for the particular
location. Default is to reject path information. PR 21059.
[André Malo]
*) mod_ext_filter: Add the ability to filter request bodies.
[Philipp Reisner <philipp.reisner linbit.com>]
*) Fix some broken log messages in WinNT MPM.
[Juan Rivera <Juan.Rivera citrix.com>]
*) prefork MPM: Use the right permissions for the directory created
for gprof support. [Jim Carlson <jcarlson jnous.com>]
*) Fix a compile failure with recent OpenSSL and picky compilers
(e.g., OpenSSL 0.9.7a and xlc_r on AIX). [Jeff Trawick]
*) OpenSSL headers should be included as "openssl/ssl.h", and not rely on
the INCLUDE path to be defined properly.
PR 11310. [Geoff Thorpe <geoff geoffthorpe.net>]
*) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli]
*) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using

[Geoff Thorpe <geoff geoffthorpe.net>]
*) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
[Ian Holsman, André Malo]
*) mod_negotiation: quality values are now parsed independent from
the current locale. level values are now really parsed as integers.
PR 17564. [André Malo]
*) Extend mod_negotiation to evaluate the environment variables
no-gzip and gzip-only-text/html the same way as mod_deflate does.
[André Malo]
*) mod_rewrite: Fix some problems reporting errors with mapping
programs (RewriteMap prg:/something). [Jeff Trawick]
*) Return 413 if chunk-ext-header is too long rather than reading from
the truncated line. PR 15857. [Justin Erenkrantz]
*) Allow restart of httpd to occur even with syntax errors in the config
file. PR 16813. [Justin Erenkrantz]
*) Use APR_LAYOUT instead of APACHE_LAYOUT in configure. PR 15679.
[Justin Erenkrantz]
*) Remove files on 'make distclean' that should be. PR 15592.
[Justin Erenkrantz]
*) Allow apachectl to perform status with links and elinks as well.
[Justin Erenkrantz]
*) mod_log_config change optional hook to return previous handler
[Ian Holsman]
*) Forward port of mod_actions' ability to handle arbitrary methods
with the Script directive. [André Malo]
*) Let suexec send a message to stderr, if it failed or its policy
was violated. This message appears in the error log and allows
for easier debugging. PR 5381, 7638, 8255, 10773. [André Malo]
*) Modify buildconf to copy all required files into httpd's tree.
[Thom May <thom planetarytramp.net>]
*) Allow mod_dav to do weak entity comparison functions.
[Justin Erenkrantz]
*) Move RFC 1413 ident requests from core to new module mod_ident.
[André Malo]
*) Add mod_authz_owner - a forward port of "Require file-owner"
and "Require file-group", which was already present in version
1.3.21. [André Malo]
*) Add mod_dav_lock - a generic subset of the DAV locking implementation.
[Justin Erenkrantz]
*) Replace some of the mutex locking in the worker MPM with
atomic operations for higher concurrency. [Brian Pane]
*) Allow 'make depend' to work with non-GCC compilers.
[Justin Erenkrantz]
*) If an httpd.conf has commented out AddModule directives,
apxs -i -a will add an un-commented AddModule directive for
the new module, which breaks the config.
PR: 11212 [Joe Orton]
*) Fix mod_proxy handling of filtered input bodies. [Justin Erenkrantz]
*) Move the check of the Expect request header field after the hook
for ap_post_read_request, since that is the only opportunity for
modules to handle Expect extensions. [Justin Erenkrantz]
*) Rewrite of aaa modules to an authn/authz model.
[Dirk-Willem van Gulik, Justin Erenkrantz]
