form request with the type of application/x-www-form-urlencoded.
[Graham Leggett]
*) mod_session_crypto: Initialise SSL in the post config hook.
[Ruediger Pluem, Graham Leggett]
*) mod_session_dbd: Add a session implementation capable of storing
session information in a SQL database via the dbd interface. Useful
for sites where session privacy is important. [Graham Leggett]
*) mod_session_crypto: Add a session encoding implementation capable
of encrypting and decrypting sessions wherever they may be stored.
Introduces a level of privacy when sessions are stored on the
browser. [Graham Leggett]
*) mod_session_cookie: Add a session implementation capable of storing
session information within cookies on the browser. Useful for high
volume sites where server bound sessions are too resource intensive.
[Graham Leggett]
*) mod_session: Add a generic session interface to unify the different
attempts at saving persistent sessions across requests.
[Graham Leggett]
*) core, authn/z: Avoid calling access control hooks for internal requests
with configurations which match those of initial request. Revert to
original behaviour (call access control hooks for internal requests
with URIs different from initial request) if any access control hooks or
providers are not registered as permitting this optimization.
Introduce wrappers for access control hook and provider registration
which can accept additional mode and flag data. [Chris Darroch]
*) mod_dav: Return "method not allowed" if the destination URI of a WebDAV
copy / move operation is no DAV resource. PR 44734 [Ruediger Pluem]
*) Introduced ap_expr API for expression evaluation.
This is adapted from mod_include, which is the first module
to use the new API.
[Nick Kew]
*) mod_authz_dbd: When redirecting after successful login/logout per
AuthzDBDRedirectQuery, do not report authorization failure, and use
first row returned by database query instead of last row.
[Chris Darroch]
*) mod_rewrite: Initialize hash needed by ap_register_rewrite_mapfunc early
enough. PR 44641 [Daniel Lescohier <daniel.lescohier cnet.com>]
*) mod_cache: Handle If-Range correctly if the cached resource was stale.
PR 44579 [Ruediger Pluem]
*) mod_ldap: Correctly return all requested attribute values
when some attributes have a null value.

SymlinksIfOwnerMatch are set [Nick Kew]
*) core: fix origin checking in SymlinksIfOwnerMatch
PR 36783 [Robert L Mathews <rob-apache.org.bugs tigertech.net>]
*) mod_proxy: Do not try a direct connection if the connection via a
remote proxy failed before and the request has a request body.
[Ruediger Pluem]
*) Added 'disablereuse' option for ProxyPass which, essentially,
disables connection pooling for the backend servers.
[Jim Jagielski]
*) Activate mod_cache, mod_file_cache and mod_disc_cache as part of the
'most' set for '--enable-modules' and '--enable-shared-mods'. Include
mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
*) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
contain public function declarations which are useful for
third party module authors. PR 42431 [Dirk-Willem van Gulik].
*) mod_dir, mod_negotiation: pass the output filter information
to newly created sub requests; as these are later on used
as true requests with an internal redirect. This allows for
mod_cache et.al. to trap the results of the redirect.
[Dirk-Willem van Gulik, Ruediger Pluem]
*) mod_proxy_ajp: Do not retry request in the case that we either failed to
sent a part of the request body or if the request is not idempotent.
PR 44334 [Ruediger Pluem]
*) mod_ldap: Add support (taking advantage of the new APR capability)
for ldap rebind callback while chasing referrals. This allows direct
searches on LDAP servers (in particular MS Active Directory 2003+)
using referrals without the use of the global catalog.
PRs 26538, 40268, and 42557 [Paul J. Reder]
*) Support chroot on Unix-family platforms
PR 43596 [Dimitar Pashev <mitko banksoft-bg.com>]

PR 34607. [Kaspar Brand <asfbugz velox.ch>]. A test configuration
can be created with test/make_sni.sh [Dirk-Willem van Gulik].
*) ApacheMonitor.exe: Introduce --kill argument for use by the
installer. This will permit the installation tool to remove
all running instances before attempting to remove the .exe.
[William Rowe]
*) mod_proxy: Lower memory consumption for short lived connections.
PR 44026. [Ruediger Pluem]
*) mod_proxy: Keep connections to the backend persistent in the HTTPS case.
[Ruediger Pluem]
*) mod_ssl: Add support for OCSP validation of client certificates.
PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
*) mod_unique_id: Fix timestamp value in UNIQUE_ID.
PR 37064 [Kobayashi <kobayashi firstserver.co.jp>]
*) mod_serf: New module for Reverse Proxying. [Paul Querna]
*) core: Add the option to keep aside a request body up to a certain
size that would otherwise be discarded, to be consumed by filters
such as mod_include. When enabled for a directory, POST requests
to shtml files can be passed through to embedded scripts as POST
requests, rather being downgraded to GET requests. [Graham Leggett]
*) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
*) scoreboard: Correctly declare ap_time_process_request.
PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
*) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
provide the unusual legacy lookup. [William Rowe]
*) mpm winnt: fix null pointer dereference
PR 42572 [Davi Arnaut]
*) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
parameters to the environment. Improve portability to
EBCDIC machines by using apr_toupper(). [Martin Kraemer]
*) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
to authorize an authenticated user via a "require ldap-group X" directive
where the user is not in group X, but is in a subgroup contained in X.
PR 42891 [Paul J. Reder]
*) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
*) ab: Add -r option to continue after socket receive errors.
[Filip Hanik <devlist hanik.com>]
*) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
for SDKs that define LDAP_NO_LIMIT to something other than -1.
[David Jones <oscaremma gmail.com>]
*) apxs: Enhance -q flag to print all known variables and their values
when invoked without variable name(s).
[William Rowe, Sander Temme]
*) apxs: Eliminate run-time check for mod_so. PR 40653.
[David M. Lee <dmlee crossroads.com>]
*) beos MPM: Create pmain pool and run modules' child_init hooks when
entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
[Chris Darroch]
*) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
cleanups registered in modules' child_init hooks are performed.
[Chris Darroch]
*) mod_dbd: Stash DBD connections in request_config of initial request
only, or else sub-requests and internal redirections may cause
entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
*) Fix issue which could cause error messages to be written to access logs
on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
*) The LockFile directive, which specifies the location of
the accept() mutex lockfile, is deprecated. Instead, the
AcceptMutex directive now takes an optional lockfile
location parameter, ala SSLMutex. [Jim Jagielski]
*) mod_authn_dbd: Export any additional columns queried in the SQL select
into the environment with the name AUTHENTICATE_<COLUMN>. This brings
mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
*) mod_dbd: Key the storage of prepared statements on the hex string
value of server_rec, rather than the server name, as the server name
may change (eg when the server name is set) at any time, causing
weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
*) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
*) sendfile_nonblocking() takes the _brigade_ as an argument, gets
the first bucket from the brigade, finds it not to be a FILE
bucket and barfs. The fix is to pass a bucket rather than a brigade.
[Niklas Edmundsson <nikke acc.umu.se>]
*) mod_rewrite: support rewritemap by SQL query [Nick Kew]
*) ap_get_server_version() has been removed. Third-party modules must
now use ap_get_server_banner() or ap_get_server_description().
[Jeff Trawick]
*) All MPMs: Introduce a check_config phase between pre_config and
open_logs, to allow modules to review interdependent configuration
directive values and adjust them while messages can still be logged
to the console. Handle relevant MPM directives during this phase
and format messages for both the console and the error log, as
appropriate. [Chris Darroch]
*) mod_proxy: don't URLencode tilde in path component
[Stijn Hoop <stijn sandcat.nl>]
*) mpm_winnt: Fix return values from wait_for_many_objects.
The return value is index to the signaled thread in the
creted_threads array. We can not use WAIT_TIMEOUT because
his value is defined as 258, thus limiting the MaxThreads
to that value. [Mladen Turk]
*) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
to circumvent the symbolic link checks imposed by FollowSymLinks and
SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
*) mod_proxy: Support environment variable interpolation in reverse
proxying directives. [Nick Kew]
*) core: Add the filename of the configuration file to the warning message
about the useless use of AllowOverride. PR 39992.
[Darryl Miles <darryl darrylmiles.org>]
*) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
The default is none as this is far greater debugging resolution than
the typical administrator is prepared to untangle. [William Rowe]
*) mod_disk_cache: If possible, check if the size of an object to cache is
within the configured boundaries before actually saving data.
[Niklas Edmundsson <nikke acc.umu.se>]
*) mod_cache: Convert all values to seconds before comparing them when
checking whether to send a Warning header for a stale response.
PR 39713. [Owen Taylor <otaylor redhat.com>]
*) mod_disk_cache: Delete temporary files if they cannot be renamed to their
final name. [Davi Arnaut <davi haxent.com.br>]

performed in the event of a fork() failure. [Chris Darroch]
*) Add support for fcgi:// proxies to mod_rewrite.

loading of worker_score structure with mod_status, and remove unused
definitions relating to old life_status field.

[Chris Darroch <chrisd pearsoncmg.com>]
*) mod_charset_lite: Remove Content-Length when output filter can
invalidate it. Warn when input filter can invalidate it.
[Jeff Trawick]
*) Authz: Add the new module mod_authn_core that will provide common
authn directives such as 'AuthType', 'AuthName'. Move the directives
'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
into mod_authn_core. [Brad Nicholes]
*) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
into the new module mod_access_compat which can be loaded to provide
support for these directives.
[Brad Nicholes]
*) Authz: Move the 'Require' directive from the core module as well as
add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
logic into the authorization processing. [Brad Nicholes]
*) Authz: Add the new module mod_authz_core which acts as the
authorization provider vector and contains common authz
directives. [Brad Nicholes]
*) Authz: Renamed mod_authz_dbm authz providers from 'group' and
'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
*) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
host-based access control provided by mod_authz_host and invoked
through the 'Require' directive. [Brad Nicholes]
*) Authz: Convert all of the authz modules from hook based to
provider based. [Brad Nicholes]
*) mod_cache: Add CacheMinExpire directive to set the minimum time in
seconds to cache a document.
[Brian Akins <brian.akins turner.com>, Ruediger Pluem]
*) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
*) Fix typo in ProxyStatus syntax error message.
[Christophe Jaillet <christophe.jaillet wanadoo.fr>]
*) Asynchronous write completion for the Event MPM. [Brian Pane]
*) Added an End-Of-Request bucket type. The logging of a request and
the freeing of its pool are now done when the EOR bucket is destroyed.
This has the effect of delaying the logging until right after the last
of the response is sent; ap_core_output_filter() calls the access logger
indirectly when it destroys the EOR bucket. [Brian Pane]
*) Rewrite of logresolve support utility: IPv6 addresses are now supported
and the format of statistical output has changed. [Colm MacCarthaigh]
*) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
*) Added new connection states for handler and write completion
[Brian Pane]
*) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
[Justin Erenkrantz]
*) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
allowing string-valued client certificate attributes to be used for
access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
