23 *) core: AllowEncodedSlashes new option NoDecode to allow encoded slashes
24 in request URL path info but not decode them. Change behavior of option
25 "On" to decode the encoded slashes as 2.0 and 2.2 do. PR 35256,
26 PR 46830. [Dan Poirier]
28 *) mod_ssl: Check SNI hostname against Host header case-insensitively.
29 PR 49491. [Mayank Agrawal <magrawal.08 gmail.com>]
31 *) mod_ldap: Add LDAPConnectionPoolTTL to give control over lifetime
32 of bound backend LDAP connections. PR47634 [Eric Covener]
34 *) mod_cache: Make CacheEnable and CacheDisable configurable per
35 directory in addition to per server, making them work from within
36 a LocationMatch. [Graham Leggett]
38 *) worker, event, prefork: Correct several issues when built as
39 DSOs; most notably, the scoreboard was reinitialized during graceful
40 restart, such that processes of the previous generation were not
41 observable. [Jeff Trawick]
43 Changes with Apache 2.3.11
45 *) mod_proxy: balancer-manager now uses POST instead of GET.
48 *) core: new util function: ap_parse_form_data(). Previously,
49 this capability was tucked away in mod_request. [Jim Jagielski]
51 *) core: new hook: ap_run_pre_read_request. [Jim Jagielski]
53 *) mod_cache: When a request other than GET or HEAD arrives, we must
54 invalidate existing cache entities as per RFC2616 13.10. PR 15868.
57 *) modules: Fix many modules that were not correctly initializing if they
58 were not active during server startup but got enabled later during a
59 graceful restart. [Stefan Fritsch]
61 *) core: Create new ap_state_query function that allows modules to determine
62 if the current configuration run is the initial one at server startup,
63 and if the server is started for testing/config dumping only.
66 *) mod_proxy: Runtime configuration of many parameters for existing
67 balancers via the balancer-manager. [Jim Jagielski]
69 *) mod_proxy: Runtime addition of new workers (BalancerMember) for existing
70 balancers via the balancer-manager. [Jim Jagielski]
72 *) mod_cache: When a bad Expires date is present, we need to behave as if
73 the Expires is in the past, not as if the Expires is missing. PR 16521.
74 [Co-Advisor <coad@measurement-factory.com>]
76 *) mod_cache: We must ignore quoted-string values that appear in a
77 Cache-Control header. PR 50199. [Graham Leggett]
79 *) mod_dav: Revert change to send 501 error if unknown Content-* header is
80 received for a PUT request. PR 42978. [Stefan Fritsch]
82 *) mod_cache: Respect s-maxage as described by RFC2616 14.9.3, which must
83 take precedence if present. PR 35247. [Graham Leggett]
85 *) mod_ssl: Fix a possible startup failure if multiple SSL vhosts
86 are configured with the same ServerName and private key file.
87 [Masahiro Matsuya <mmatsuya redhat.com>, Joe Orton]
89 *) mod_socache_dc: Make module compile by fixing some typos.
90 PR 50735 [Mark Montague <mark catseye.org>]

96 PR 50434 [Stefan Fritsch]
98 *) core: Add support to set variables with the 'Define' directive. The
99 variables that can then be used in the config using the ${VAR} syntax
100 known from envvar interpolation. [Stefan Fritsch]
102 *) mod_proxy_http: make adding of X-Forwarded-* headers configurable.
103 ProxyAddHeaders defaults to On. [Vincent Deffontaines]
105 *) mod_slotmem_shm: Increase memory alignment for slotmem data.
108 *) mod_ssl: Add config options for OCSP: SSLOCSPResponderTimeout,
109 SSLOCSPResponseMaxAge, SSLOCSPResponseTimeSkew.
110 [Kaspar Brand <httpd-dev.2011 velox.ch>]
112 *) mod_ssl: Revamp output buffering to reduce network overhead for
113 output fragmented into many buckets, such as chunked HTTP responses.
116 *) core: Apply <If> sections to all requests, not only to file base requests.
117 Allow to use <If> inside <Directory>, <Location>, and <Files> sections.
118 The merging of <If> sections now happens after the merging of <Location>
119 sections, even if an <If> section is embedded inside a <Directory> or
120 <Files> section. [Stefan Fritsch]
122 *) mod_proxy: Refactor usage of shared data by dropping the scoreboard
123 and using slotmem. Create foundation for dynamic growth/changes of
124 members within a balancer. Remove BalancerNonce in favor of a
125 per-balancer 'nonce' parameter. [Jim Jagielski]
127 *) mod_status: Don't show slots which are disabled by MaxClients as open.
128 PR: 47022 [Jordi Prats <jordi prats gmail com>, Stefan Fritsch]
130 *) mpm_prefork: Fix ap_mpm_query results for AP_MPMQ_MAX_DAEMONS and
133 *) mod_authz_core: Fix bug in merging logic if user-based and non-user-based
134 authorization directives were mixed. [Stefan Fritsch]
136 *) mod_authn_socache: change directive name from AuthnCacheProvider
137 to AuthnCacheProvideFor. The term "provider" is overloaded in
138 this module, and we should avoid confusion between the provider
139 of a backend (AuthnCacheSOCache) and the authn provider(s) for
140 which this module provides cacheing (AuthnCacheProvideFor).
143 *) mod_proxy_http: Allocate the fake backend request from a child pool
144 of the backend connection, instead of misusing the pool of the frontend
145 request. Fixes a thread safety issue where buckets set aside in the
146 backend connection leak into other threads, and then disappear when
147 the frontend request is cleaned up, in turn causing corrupted buckets
148 to make other threads spin. [Graham Leggett]
150 *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables
151 to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and
152 escape other special characters with backslashes. The old format can
153 still be used with the LegacyDNStringFormat argument to SSLOptions.
155 *) core, mod_rewrite: Make the REQUEST_SCHEME variable available to
156 scripts and mod_rewrite. [Stefan Fritsch]
158 *) mod_rewrite: Allow to use arbitrary boolean expressions (ap_expr) in
159 RewriteCond. [Stefan Fritsch]
161 *) mod_rewrite: Allow to unset environment variables using E=!VAR.
162 PR 49512. [Mark Drayton <mark markdrayton info>, Stefan Fritsch]
164 *) mod_headers: Restore the 2.3.8 and earlier default for the first
165 argument of the Header directive ("onsuccess"). [Eric Covener]
167 *) core: Disallow the mixing of relative and absolute Options PR 33708.
168 [Sönke Tesch <st kino-fahrplan.de>]
170 *) core: When exporting request headers to HTTP_* environment variables,
171 drop variables whose names contain invalid characters. Describe in the
172 docs how to restore the old behaviour. [Malte S. Stretz <mss apache org>]
174 *) core: When selecting an IP-based virtual host, favor an exact match for
175 the port over a wildcard (or omitted) port instead of favoring the one
176 that came first in the configuration file. [Eric Covener]
178 *) core: Overlapping virtual host address/port combinations now implicitly
179 enable name-based virtual hosting for that address. The NameVirtualHost
180 directive has no effect, and _default_ is interpreted the same as "*".
183 *) core: In the absence of any Options directives, the default is now
184 "FollowSymlinks" instead of "All". [Igor Galić]
186 *) rotatelogs: Add -e option to write logs through to stdout for optional
187 further processing. [Graham Leggett]
189 *) mod_ssl: Correctly read full lines in input filter when the line is
190 incomplete during first read. PR 50481. [Ruediger Pluem]
192 *) mod_authz_core: Add AuthzSendForbiddenOnFailure directive to allow
193 sending '403 FORBIDDEN' instead of '401 UNAUTHORIZED' if authorization
194 fails for an authenticated user. PR 40721. [Stefan Fritsch]
196 Changes with Apache 2.3.10
198 *) mod_rewrite: Don't implicitly URL-escape the original query string
199 when no substitution has changed it. PR 50447. [Eric Covener]
201 *) core: Honor 'AcceptPathInfo OFF' during internal redirects,
202 such as per-directory mod_rewrite substitutions. PR 50349.
205 *) mod_rewrite: Add 'RewriteOptions InheritBefore' to put the base
206 rules/conditions before the overridden rules/conditions. PR 39313.
207 [Jérôme Grandjanny <jerome.grandjanny cea.fr>]
209 *) mod_autoindex: add IndexIgnoreReset to reset the list of IndexIgnored
210 filenames in higher precedence configuration sections. PR 24243.
213 *) mod_cgid: RLimit* directive support for mod_cgid. PR 42135
216 *) core: Fail startup when the argument to ServerName looks like a glob
217 or a regular expression instead of a hostname (*?[]). PR 39863
218 [Rahul Nair <rahul.g.nair gmail.com>]
220 *) mod_userdir: Add merging of enable, disable, and filename arguments
221 to UserDir directive, leaving enable/disable of userlists unmerged.
222 PR 44076 [Eric Covener]
224 *) httpd: When no -k option is provided on the httpd command line, the server
225 was starting without checking for an existing pidfile. PR 50350
228 *) mod_proxy: Put the worker in error state if the SSL handshake with the
229 backend fails. PR 50332.
230 [Daniel Ruggeri <DRuggeri primary.net>, Ruediger Pluem]
232 *) mod_cache_disk: Fix Windows build which was broken after renaming
233 the module. [Gregg L. Smith]
235 Changes with Apache 2.3.9
237 *) SECURITY: CVE-2010-1623 (cve.mitre.org)
238 Fix a denial of service attack against mod_reqtimeout.
241 *) mod_headers: Change default first argument of Header directive
242 from "onsuccess" to "always". [Eric Covener]
244 *) mod_include: Add the onerror attribute to the include element,
245 allowing an URL to be specified to include on error. [Graham
248 *) mod_cache_disk: mod_disk_cache renamed to mod_cache_disk, to be
249 consistent with the naming of other modules. [Graham Leggett]
251 *) mod_setenvif: Add SetEnvIfExpr directive to set env var depending on
252 expression. [Stefan Fritsch]
254 *) mod_proxy: Fix ProxyPassInterpolateEnv directive. PR 50292.
257 *) suEXEC: Add Suexec directive to disable suEXEC without renaming the
258 binary (Suexec Off), or force startup failure if suEXEC is required
259 but not supported (Suexec On). Change SuexecUserGroup to fail
260 startup instead of just printing a warning if suEXEC is disabled.
263 *) core: Add Error directive for aborting startup or htaccess processing
264 with a specified error message. [Jeff Trawick]
266 *) mod_rewrite: Fix the RewriteEngine directive to work within a
267 location. Previously, once RewriteEngine was switched on globally,
268 it was impossible to switch off. [Graham Leggett]
270 *) core, mod_include, mod_ssl: Move the expression parser derived from
271 mod_include back into mod_include. Replace ap_expr with a parser
272 derived from mod_ssl's parser. Make mod_ssl use the new parser. Rework
273 ap_expr's public interface and provide hooks for modules to add variables
274 and functions. [Stefan Fritsch]
276 *) core: Do the hook sorting earlier so that the hooks are properly sorted
277 for the pre_config hook and during parsing the config. [Stefan Fritsch]
279 *) core: In the absence of any AllowOverride directives, the default is now
280 "None" instead of "All". PR49823 [Eric Covener]
282 *) mod_proxy: Don't allow ProxyPass or ProxyPassReverse in
283 <Directory> or <Files>. PR47765 [Eric Covener]
285 *) prefork/worker/event MPMS: default value (when no directive is present)
286 of MaxConnectionsPerChild/MaxRequestsPerChild is changed to 0 from 10000
287 to match default configuration and manual. PR47782 [Eric Covener]
289 *) proxy_connect: Don't give up in the middle of a CONNECT tunnel
290 when the child process is starting to exit. PR50220. [Eric Covener]
292 *) mod_autoindex: Fix inheritance of mod_autoindex directives into
293 contexts that don't have any mod_autoindex directives. PR47766.
296 *) mod_rewrite: Add END flag for RewriteRule to prevent further rounds
297 of rewrite processing when a per-directory substitution occurs.
300 *) mod_ssl: Make sure to always log an error if loading of CA certificates
301 fails. PR 40312. [Paul Tiemann <issues apache org ourdetour com>]
303 *) mod_dav: Send 501 error if unknown Content-* header is received for a PUT
304 request (RFC 2616 9.6). PR 42978. [Stefan Fritsch]
306 *) mod_dav: Send 400 error if malformed Content-Range header is received for
307 a put request (RFC 2616 14.16). PR 49825. [Stefan Fritsch]
309 *) mod_proxy: Release the backend connection as soon as EOS is detected,
310 so the backend isn't forced to wait for the client to eventually
311 acknowledge the data. [Graham Leggett]
313 *) mod_proxy: Optimise ProxyPass within a Location so that it is stored
314 per-directory, and chosen during the location walk. Make ProxyPass
315 work correctly from within a LocationMatch. [Graham Leggett]
317 *) core: Fix segfault if per-module LogLevel is on virtual host
318 scope. PR 50117. [Stefan Fritsch]
320 *) mod_proxy: Move the ProxyErrorOverride directive to have per
321 directory scope. [Graham Leggett]
323 *) mod_allowmethods: New module to deny certain HTTP methods without
324 interfering with authentication/authorization. [Paul Querna,
325 Igor Galić, Stefan Fritsch]
327 *) mod_ssl: Log certificate information and improve error message if client
328 cert verification fails. PR 50093, PR 50094. [Lassi Tuura <lat cern ch>,
331 *) htcacheclean: Teach htcacheclean to limit cache size by number of
332 inodes in addition to size of files. Prevents a cache disk from
333 running out of space when many small files are cached.
336 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
337 describes more accurately what the directive does. The old name
338 still works but logs a warning. [Stefan Fritsch]
340 *) mod_cache: Optionally serve stale data when a revalidation returns a
341 5xx response, controlled by the CacheStaleOnError directive.
344 *) htcacheclean: Allow the listing of valid URLs within the cache, with
345 the option to list entry metadata such as sizes and times. [Graham
348 *) mod_cache: correctly parse quoted strings in cache headers.
351 *) mod_cache: Allow control over the base URL of reverse proxied requests
352 using the CacheKeyBaseURL directive, so that the cache key can be
353 calculated from the endpoint URL instead of the server URL. [Graham
356 *) mod_cache: CacheLastModifiedFactor, CacheStoreNoStore, CacheStorePrivate,
357 CacheStoreExpired, CacheIgnoreNoLastMod, CacheDefaultExpire,
358 CacheMinExpire and CacheMaxExpire can be set per directory/location.
361 *) mod_disk_cache: CacheMaxFileSize, CacheMinFileSize, CacheReadSize and
362 CacheReadTime can be set per directory/location. [Graham Leggett]
364 *) core: Speed up config parsing if using a very large number of config
365 files. PR 50002 [andrew cloudaccess net]
367 *) mod_cache: Support the caching of HEAD requests. [Graham Leggett]
369 *) htcacheclean: Allow the option to round up file sizes to a given
370 block size, improving the accuracy of disk usage. [Graham Leggett]
372 *) mod_ssl: Add authz providers for use with mod_authz_core and its
373 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
374 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
375 'ssl-require' (expressions with same syntax as SSLRequire).
378 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
379 bison instead of yacc. [Stefan Fritsch]
381 *) mod_disk_cache: Change on-disk header file format to support the
382 link of the device/inode of the data file to the matching header
383 file, and to support the option of not writing a data file when
384 the data file is empty. [Graham Leggett]
386 *) core/mod_unique_id: Add generate_log_id hook to allow to use
387 the ID generated by mod_unique_id as error log ID for requests.
390 *) mod_cache: Make sure that we never allow a 304 Not Modified response
391 that we asked for to leak to the client should the 304 response be
392 uncacheable. PR45341 [Graham Leggett]
394 *) mod_cache: Add the cache_status hook to register the final cache
395 decision hit/miss/revalidate. Add optional support for an X-Cache
396 and/or an X-Cache-Detail header to add the cache status to the
397 response. PR48241 [Graham Leggett]
399 *) mod_authz_host: Add 'local' provider that matches connections originating
400 on the local host. PR 19938. [Stefan Fritsch]
402 *) Event MPM: Fix crash accessing pollset on worker thread when child
403 process is exiting. [Jeff Trawick]
405 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
406 pass the system library path (LD_LIBRARY_PATH or platform-specific
407 variables) along with the system PATH, by default. Both should be
408 overridden together as desired using PassEnv etc; see mod_env.
411 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
412 capture a stale backend response, perform If-Modified-Since requests
413 against the backend, and serving from the cache all 304 responses.
414 This restores pre-2.2.4 cache behavior. [William Rowe]
416 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
417 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
418 the ambiguity of the symlink test "-ltest", introduce -h or -L as
419 symlink test operators. [William Rowe]
421 *) mod_cache: Give the cache provider the opportunity to choose to cache
422 or not cache based on the buckets present in the brigade, such as the
423 presence of a FILE bucket.
426 *) mod_authz_core: Allow authz providers to check args while reading the
427 config and allow to cache parsed args. Move 'all' and 'env' authz
428 providers from mod_authz_host to mod_authz_core. Add 'method' authz
429 provider depending on the HTTP method. [Stefan Fritsch]
431 *) mod_include: Move the request_rec within mod_include to be
432 exposed within include_ctx_t. [Graham Leggett]
434 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
435 variable being echoed or set to be decoded and then encoded as separate
436 steps. PR47686 [Graham Leggett]
438 *) mod_cache: Add a discrete commit_entity() provider function within the
439 mod_cache provider interface which is called to indicate to the
440 provider that caching is complete, giving the provider the opportunity
441 to commit temporary files permanently to the cache in an atomic
442 fashion. Replace the inconsistent use of error cleanups with a formal
443 set of pool cleanups attached to a subpool, which is destroyed on error.
446 *) mod_cache: Change the signature of the store_body() provider function
447 within the mod_cache provider interface to support an "in" brigade
448 and an "out" brigade instead of just a single input brigade. This
449 gives a cache provider the option to consume only part of the brigade
450 passed to it, rather than the whole brigade as was required before.
451 This fixes an out of memory and a request timeout condition that would
452 occur when the original document was a large file. Introduce
453 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
454 the amount of data to attempt to cache at a time. [Graham Leggett]
456 *) core: Add ErrorLogFormat to allow configuring error log format, including
457 additional information that is logged once per connection or request. Add
458 error log IDs for connections and request to allow correlating error log
459 lines and the corresponding access log entry. [Stefan Fritsch]
461 *) core: Disable sendfile by default. [Stefan Fritsch]
463 *) mod_cache: Check the request to determine whether we are allowed
464 to return cached content at all, and respect a "Cache-Control:
465 no-cache" header from a client. Previously, "no-cache" would
466 behave like "max-age=0". [Graham Leggett]
468 *) mod_cache: Use a proper filter context to hold filter data instead
469 of misusing the per-request configuration. Fixes a segfault on trunk
470 when the normal handler is used. [Graham Leggett]
472 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
473 it is too long. PR 49388. [Stefan Fritsch]
475 *) vhosts: Do not allow _default_ in NameVirtualHost, or mixing *
476 and non-* ports on NameVirtualHost, or multiple NameVirtualHost
477 directives for the same address:port, or NameVirtualHost
478 directives with no matching VirtualHosts, or multiple ip-based
479 VirtualHost sections for the same address:port. These were
480 previously accepted with a warning, but the behavior was
481 undefined. [Dan Poirier]

579 mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
580 attack when compiled against OpenSSL version 0.9.8m or later. Introduces
581 the 'SSLInsecureRenegotiation' directive to reopen this vulnerability
582 and offer unsafe legacy renegotiation with clients which do not yet
583 support the new secure renegotiation protocol, RFC 5746.
584 [Joe Orton, and with thanks to the OpenSSL Team]
586 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
587 mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
588 by rejecting any client-initiated renegotiations. Forcibly disable
589 keepalive for the connection if there is any buffered data readable. Any
590 configuration which requires renegotiation for per-directory/location
591 access control is still vulnerable, unless using OpenSSL >= 0.9.8l.

595 mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent
596 when request headers indicate a request body is incoming; not a case of

599 *) SECURITY: CVE-2010-0425 (cve.mitre.org)
600 mod_isapi: Do not unload an isapi .dll module until the request
601 processing is completed, avoiding orphaned callback pointers.
602 [Brett Gervasoni <brettg senseofsecurity.com>, Jeff Trawick]
604 *) core: Filter init functions are now run strictly once per request
605 before handler invocation. The init functions are no longer run
606 for connection filters. PR 49328. [Joe Orton]
608 *) core: Adjust the output filter chain correctly in an internal
609 redirect from a subrequest, preserving filters from the main
610 request as necessary. PR 17629. [Joe Orton]
612 *) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
613 Response if they so choose to do so. Previously an attempt to cache a 206
614 was arbitrarily allowed if the response contained an Expires or
615 Cache-Control header, and arbitrarily denied if both headers were missing.

642 mod_ssl/mod_proxy*: Adjust loglevels to be less verbose at levels info
644 mod_dumpio: Replace DumpIOLogLevel with trace log levels.
647 *) mod_ldap: LDAP caching was suppressed (and ldap-status handler returns
648 title page only) when any mod_ldap directives were used in VirtualHost
649 context. [Eric Covener]
651 *) mod_disk_cache: Decline the opportunity to cache if the response is
652 a 206 Partial Content. This stops a reverse proxied partial response
653 from becoming cached, and then being served in subsequent responses.
656 *) mod_deflate: avoid the risk of forwarding data before headers are set.

741 setting only, matching most of the documentation and examples.
742 PR 46541 [Paul Reder, Eric Covener]
744 *) mod_ldap: LDAPTrustedClientCert now accepts CA_DER/CA_BASE64 argument
745 types previously allowed only in LDAPTrustedGlobalCert. [Eric Covener]
747 *) mod_negotiation: Preserve query string over multiviews negotiation.
748 This buglet was fixed for type maps in 2.2.6, but the same issue
749 affected multiviews and was overlooked.

777 stack. Can be used to turn an output filter into a web service.
780 *) mod_proxy_http: Make sure that when an ErrorDocument is served
781 from a reverse proxied URL, that the subrequest respects the status
782 of the original request. This brings the behaviour of proxy_handler
783 in line with default_handler. PR 47106. [Graham Leggett]

1673 *) All MPMs: Introduce a check_config phase between pre_config and
1674 open_logs, to allow modules to review interdependent configuration
1675 directive values and adjust them while messages can still be logged
1676 to the console. Handle relevant MPM directives during this phase
1677 and format messages for both the console and the error log, as
1678 appropriate. [Chris Darroch]
1680 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
1681 to circumvent the symbolic link checks imposed by FollowSymLinks and
1682 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
1684 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
1685 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
1686 The default is none as this is far greater debugging resolution than
1687 the typical administrator is prepared to untangle. [William Rowe]
1689 *) mod_disk_cache: If possible, check if the size of an object to cache is
1690 within the configured boundaries before actually saving data.
1691 [Niklas Edmundsson <nikke acc.umu.se>]
1693 *) Worker and event MPMs: Remove improper scoreboard updates which were
1694 performed in the event of a fork() failure. [Chris Darroch]
1696 *) Add support for fcgi:// proxies to mod_rewrite.
1697 [Markus Schiegl <ms schiegl.com>]
1699 *) Remove incorrect comments from scoreboard.h regarding conditional
1700 loading of worker_score structure with mod_status, and remove unused
1701 definitions relating to old life_status field.
1702 [Chris Darroch <chrisd pearsoncmg.com>]
1704 *) Remove allocation of memory for unused array of lb_score pointers
1705 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
1707 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
1708 [Garrett Rooney, Jim Jagielski, Paul Querna]
1710 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
1711 [Chris Darroch <chrisd pearsoncmg.com>]
1713 *) mod_charset_lite: Remove Content-Length when output filter can
1714 invalidate it. Warn when input filter can invalidate it.
1717 *) Authz: Add the new module mod_authn_core that will provide common
1718 authn directives such as 'AuthType', 'AuthName'. Move the directives
1719 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
1720 into mod_authn_core. [Brad Nicholes]
1722 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
1723 into the new module mod_access_compat which can be loaded to provide
1724 support for these directives.
1727 *) Authz: Move the 'Require' directive from the core module as well as
1728 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
1729 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
1730 logic into the authorization processing. [Brad Nicholes]
1732 *) Authz: Add the new module mod_authz_core which acts as the
1733 authorization provider vector and contains common authz
1734 directives. [Brad Nicholes]
1736 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
1737 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
1739 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
1740 host-based access control provided by mod_authz_host and invoked
1741 through the 'Require' directive. [Brad Nicholes]
1743 *) Authz: Convert all of the authz modules from hook based to
1744 provider based. [Brad Nicholes]
1746 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
1747 seconds to cache a document.
1748 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
1750 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
1752 *) Fix typo in ProxyStatus syntax error message.
1753 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
1755 *) Asynchronous write completion for the Event MPM. [Brian Pane]
1757 *) Added an End-Of-Request bucket type. The logging of a request and
1758 the freeing of its pool are now done when the EOR bucket is destroyed.
1759 This has the effect of delaying the logging until right after the last
1760 of the response is sent; ap_core_output_filter() calls the access logger
1761 indirectly when it destroys the EOR bucket. [Brian Pane]
1763 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
1764 and the format of statistical output has changed. [Colm MacCarthaigh]
1766 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
1768 *) Added new connection states for handler and write completion
1771 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
1774 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
1775 allowing string-valued client certificate attributes to be used for
1776 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
