5 16MB. PR 43084. [Stefan Fritsch]
7 *) core: Increase length limit of lines in the configuration file to 16MB.
8 PR 45888. PR 50824. [Stefan Fritsch]
10 *) core: Add API for resizable buffers. [Stefan Fritsch]
12 *) mod_ldap: Enable LDAPConnectionTimeout for LDAP toolkits that have
13 LDAP_OPT_CONNECT_TIMEOUT instead of LDAP_OPT_NETWORK_TIMEOUT, such
14 as Tivoli Directory Server 6.3 and later. [Eric Covener]
16 *) mod_ldap: Change default number of retries from 10 to 3, and add
17 an LDAPRetries and LDAPRetryDelay directives. [Eric Covener]
19 *) mod_authnz_ldap: Don't retry during authentication, because this just
20 multiplies the ample retries already being done by mod_ldap. [Eric Covener]
22 *) configure: Allow to explicitly disable modules even with module selection
23 'reallyall'. [Stefan Fritsch]
25 *) mod_rewrite: Check validity of each internal (int:) RewriteMap even if the
26 RewriteEngine is disabled in server context, avoiding a crash while
27 referencing the invalid int: map at runtime. PR 50994.
28 [Ben Noordhuis <info noordhuis nl>]
30 *) mod_ssl, configure: require OpenSSL 0.9.7 or later. [Kaspar Brand]
32 *) mod_ssl: remove ssl_toolkit_compat layer. [Kaspar Brand]
34 *) mod_ssl, configure, ab: drop support for RSA BSAFE SSL-C toolkit.
37 *) mod_usertrack: Run mod_usertrack earlier in the fixups hook to ensure the
38 cookie is set when modules such as mod_rewrite trigger a redirect. Also
39 use r->err_headers_out for the cookie, for the same reason. PR29755.
40 [Sami J. Mäkinen <sjm almamedia fi>, Eric Covener]
42 *) mod_proxy_http, mod_proxy_connect: Add 'proxy-status' and
43 'proxy-source-port' request notes for logging. PR 30195. [Stefan Fritsch]
45 *) configure: Enable ldap modules in 'all' and 'most' selections if ldap
46 is compiled into apr-util. [Stefan Fritsch]
48 *) core: Add ap_check_cmd_context()-check if a command is executed in
49 .htaccess file. [Stefan Fritsch]
51 *) mod_deflate: Fix endless loop if first bucket is metadata. PR 51590.

54 Changes with Apache 2.3.14
56 *) mod_proxy_ajp: Improve trace logging. [Rainer Jung]
58 *) mod_proxy_ajp: Respect "reuse" flag in END_REPONSE packets.
61 *) mod_proxy: enable absolute URLs to be rewritten with ProxyPassReverse,
62 e.g. to reverse proxy "Location: https://other-internal-server/login"
65 *) prefork, worker, event: Make sure crashes are logged to the error log if
66 httpd has already detached from the console. [Stefan Fritsch]
68 *) prefork, worker, event: Reduce period during startup/restart where a
69 successive signal may be lost. PR 43696. [Arun Bhalla <arun shme net>]
71 *) mod_allowmethods: Correct Merging of "reset" and do not allow an
72 empty parameter list for the AllowMethods directive. [Rainer Jung]
74 *) configure: Update selection of modules for 'all' and 'most'. 'all' will
75 now enable all modules except for example and test modules. Make the
76 selection for 'most' more useful (including ssl and proxy). Both 'all'
77 and 'most' will now disable modules if dependencies are missing instead
78 of aborting. If a specific module is requested with --enable-XXX=yes,
79 missing dependencies will still cause configure to exit with an error.
82 *) mod_ldap: Revert the integration of apr-ldap as ap_ldap which was done
83 in 2.3.13. [Stefan Fritsch]
85 *) core: For '*' or '_default_' vhosts, use a wildcard address of any
86 address family, rather than IPv4 only. [Joe Orton]
88 *) core, mod_rewrite, mod_ssl, mod_nw_ssl: Make the SERVER_NAME variable
89 include [ ] for literal IPv6 addresses, as mandated by RFC 3875.

96 ap_scan_script_header_err*_ex functions that take a module index for
98 mod_cgi, mod_cgid, mod_proxy_fcgi, mod_proxy_scgi, mod_isapi: Use the
99 new functions in order to make logging configurable per-module.
102 *) mod_dir: Add DirectoryIndexRedirect to send an external redirect to
103 the proper index. [Eric Covener]
105 *) mod_deflate: Don't try to compress requests with a zero sized body.

116 *) mod_rewrite: Fix regexp RewriteCond with NoCase. [Stefan Fritsch]
118 *) mod_log_debug: New module that allows to log custom messages at various
119 phases in the request processing. [Stefan Fritsch]
121 *) mod_ssl: Add some debug logging when loading server certificates.
122 PR 37912. [Nick Burch <nick burch alfresco com>]
124 *) configure: Support reallyall option also for --enable-mods-static.
127 *) mod_socache_dc: add --with-distcache to configure for choosing
128 the distcache installation directory. [Rainer Jung]
130 *) mod_socache_dc: use correct build variable MOD_SOCACHE_DC_LDADD
131 instead of MOD_SOCACHE_LDADD in build macro. [Rainer Jung]
133 *) mod_lua, mod_deflate: respect platform specific runpath linker
136 *) configure: Only link the httpd binary against PCRE. No other support
137 binary needs PCRE. [Rainer Jung]
139 *) configure: tolerate dependency checking failures for modules if
140 they have been enabled implicitely. [Rainer Jung]
142 *) configure: Allow to specify module specific custom linker flags via
143 the MOD_XXX_LDADD variables. [Rainer Jung]
145 Changes with Apache 2.3.13
147 *) ab: Support specifying the local address to use. PR 48930.
148 [Peter Schuller <scode spotify com>]
150 *) core: Add support to ErrorLogFormat for logging the system unique
151 thread id under Linux. [Stefan Fritsch]
153 *) event: New AsyncRequestWorkerFactor directive to influence how many
154 connections will be accepted per process. [Stefan Fritsch]
156 *) prefork, worker, event: Rename MaxClients to MaxRequestWorkers which
157 describes more accurately what it does. [Stefan Fritsch]
159 *) rotatelogs: Add -p argument to specify custom program to invoke
160 after a log rotation. PR 51285. [Sven Ulland <sveniu ifi.uio.no>,
163 *) mod_ssl: Don't do OCSP checks for valid self-issued certs. [Kaspar Brand]
165 *) mod_ssl: Avoid unnecessary renegotiations with SSLVerifyDepth 0.
166 PR 48215. [Kaspar Brand]
168 *) mod_status: Display information about asynchronous connections in the
169 server-status. PR 44377. [Stefan Fritsch]
171 *) mpm_event: If the number of connections of a process is very high, or if
172 all workers are busy, don't accept new connections in that process.
175 *) mpm_event: Process lingering close asynchronously instead of tying up
176 worker threads. [Jeff Trawick, Stefan Fritsch]
178 *) mpm_event: If MaxMemFree is set, limit the number of pools that is kept
179 around. [Stefan Fritsch]
181 *) mpm_event: Fix graceful restart aborting connections. PR 43359.
182 [Takashi Sato <takashi lans-tv com>]
184 *) mod_ssl: Disable AECDH ciphers in example config. PR 51363.
185 [Rob Stradling <rob comodo com>]
187 *) core: Introduce new function ap_get_conn_socket() to access the socket of
188 a connection. [Stefan Fritsch]

194 CONTEXT_DOCUMENT_ROOT, CONTEXT_PREFIX. PR 26052. PR 46198.
197 *) core: Allow to override document_root on a per-request basis. Introduce
198 new context_document_root and context_prefix which provide information
199 about non-global URI-to-directory mappings (from e.g. mod_userdir or
200 mod_alias) to scripts. PR 49705. [Stefan Fritsch]
202 *) core: Add <ElseIf> and <Else> to complement <If> sections.
205 *) mod_ext_filter: Remove DebugLevel option in favor of per-module loglevel.
208 *) mod_include: Make the "#if expr" element use the new "ap_expr" expression
209 parser. The old parser can still be used by setting the new directive
210 SSILegacyExprParser. [Stefan Fritsch]
212 *) core: Add some features to ap_expr for use by mod_include: a restricted
213 mode that does not allow to bypass request access restrictions; new
214 variables DOCUMENT_URI (alias for REQUEST_URI), LAST_MODIFIED; -A as an
215 alias for -U; an additional data entry in ap_expr_eval_ctx_t for use by
216 the consumer; an extensible ap_expr_exec_ctx() API that allows to use that
217 data entry. [Stefan Fritsch]
219 *) mod_include: Merge directory configs instead of one SSI* config directive
220 causing all other per-directory SSI* config directives to be reset.
223 *) mod_charset_lite: Remove DebugLevel option in favour of per-module
224 loglevel. [Stefan Fritsch]
226 *) core: Add ap_regexec_len() function that works with non-null-terminated
227 strings. PR 51231. [Yehezkel Horowitz <horowity checkpoint com>]
229 *) mod_authnz_ldap: If the LDAP server returns constraint violation,
230 don't treat this as an error but as "auth denied". [Stefan Fritsch]
232 *) mod_proxy_fcgi|scgi: Add support for "best guess" of PATH_INFO
233 for SCGI/FCGI. PR 50880, 50851. [Mark Montague <mark catseye.org>,
236 *) mod_cache: When content is served stale, and there is no means to
237 revalidate the content using ETag or Last-Modified, and we have
238 mandated no stale-on-error behaviour, stand down and don't cache.
239 Saves a cache write that will never be read.
242 *) mod_reqtimeout: Fix a timed out connection going into the keep-alive
243 state after a timeout when discarding a request body. PR 51103.
246 *) core: Add various file existance test operators to ap_expr.

262 *) mod_authnz_ldap: Resolve crash when LDAP is used for authorization only
263 [Scott Hill <shill genscape.com>]
265 *) support: Make sure check_forensic works with mod_unique_id loaded
268 *) Add child_status hook for tracking creation/termination of MPM child
269 processes. Add end_generation hook for notification when the last
270 MPM child of a generation exits. [Jeff Trawick]
272 *) mod_ldap: Make LDAPSharedCacheSize 0 create a non-shared-memory cache per
273 process as opposed to disabling caching completely. This allows to use
274 the non-shared-memory cache as a workaround for the shared memory cache
275 not being available during graceful restarts. PR 48958. [Stefan Fritsch]
277 *) Add new ap_reserve_module_slots/ap_reserve_module_slots_directive API,
278 necessary if a module (like mod_perl) registers additional modules late
279 in the startup phase. [Stefan Fritsch]
281 *) core: Prevent segfault if DYNAMIC_MODULE_LIMIT is reached. PR 51072.
282 [Torsten Förtsch <torsten foertsch gmx net>]

290 [Torsten Förtsch <torsten foertsch gmx net>]
292 *) mod_ssl, ab: Support OpenSSL compiled without SSLv2 support.
295 *) core: Abort if the MPM is changed across restart. [Jeff Trawick]
297 *) mod_proxy_ajp: Add support for 'ProxyErrorOverride on'. PR 50945.
298 [Peter Pramberger <peter pramberger.at>, Jim Jagielski]
300 *) mod_proxy_fcgi: Add support for 'ProxyErrorOverride on'. PR 50913.
301 [Mark Montague <mark catseye.org>, Jim Jagielski]
303 *) core: Change the APIs of ap_cfg_getline() and ap_cfg_getc() to return an
304 error code. Abort with a nice error message if a config line is too long.
305 Partial fix for PR 50824. [Stefan Fritsch]
307 *) mod_info: Dump config to stdout during startup if -DDUMP_CONFIG is
308 specified. PR 31956. [Stefan Fritsch]
310 *) Restore visibility of DEFAULT_PIDLOG to core and modules. MPM
311 helper function ap_remove_pid() added. [Jeff Trawick]

329 *) mod_ldap: Add LDAPConnectionPoolTTL to give control over lifetime
330 of bound backend LDAP connections. PR47634 [Eric Covener]
332 *) mod_cache: Make CacheEnable and CacheDisable configurable per
333 directory in addition to per server, making them work from within
334 a LocationMatch. [Graham Leggett]
336 *) worker, event, prefork: Correct several issues when built as
337 DSOs; most notably, the scoreboard was reinitialized during graceful
338 restart, such that processes of the previous generation were not
339 observable. [Jeff Trawick]
341 Changes with Apache 2.3.11
343 *) mod_win32: Added shebang check for '! so that .vbs scripts work as CGI.
344 Win32's cscript interpreter can only use a single quote as comment char.
347 *) mod_proxy: balancer-manager now uses POST instead of GET.
350 *) core: new util function: ap_parse_form_data(). Previously,
351 this capability was tucked away in mod_request. [Jim Jagielski]
353 *) core: new hook: ap_run_pre_read_request. [Jim Jagielski]
355 *) mod_cache: When a request other than GET or HEAD arrives, we must
356 invalidate existing cache entities as per RFC2616 13.10. PR 15868.
359 *) modules: Fix many modules that were not correctly initializing if they
360 were not active during server startup but got enabled later during a
361 graceful restart. [Stefan Fritsch]
363 *) core: Create new ap_state_query function that allows modules to determine
364 if the current configuration run is the initial one at server startup,
365 and if the server is started for testing/config dumping only.
368 *) mod_proxy: Runtime configuration of many parameters for existing
369 balancers via the balancer-manager. [Jim Jagielski]
371 *) mod_proxy: Runtime addition of new workers (BalancerMember) for existing
372 balancers via the balancer-manager. [Jim Jagielski]
374 *) mod_cache: When a bad Expires date is present, we need to behave as if
375 the Expires is in the past, not as if the Expires is missing. PR 16521.
376 [Co-Advisor <coad@measurement-factory.com>]
378 *) mod_cache: We must ignore quoted-string values that appear in a
379 Cache-Control header. PR 50199. [Graham Leggett]
381 *) mod_dav: Revert change to send 501 error if unknown Content-* header is
382 received for a PUT request. PR 42978. [Stefan Fritsch]
384 *) mod_cache: Respect s-maxage as described by RFC2616 14.9.3, which must
385 take precedence if present. PR 35247. [Graham Leggett]
387 *) mod_ssl: Fix a possible startup failure if multiple SSL vhosts
388 are configured with the same ServerName and private key file.
389 [Masahiro Matsuya <mmatsuya redhat.com>, Joe Orton]
391 *) mod_socache_dc: Make module compile by fixing some typos.
392 PR 50735 [Mark Montague <mark catseye.org>]
394 *) prefork: Update MPM state in children during a graceful stop or
395 restart. PR 41743. [Andrew Punch <andrew.punch 247realmedia.com>]
397 *) mod_mime: Ignore leading dots when looking for mime extensions.
398 PR 50434 [Stefan Fritsch]
400 *) core: Add support to set variables with the 'Define' directive. The
401 variables that can then be used in the config using the ${VAR} syntax
402 known from envvar interpolation. [Stefan Fritsch]
404 *) mod_proxy_http: make adding of X-Forwarded-* headers configurable.
405 ProxyAddHeaders defaults to On. [Vincent Deffontaines]
407 *) mod_slotmem_shm: Increase memory alignment for slotmem data.
410 *) mod_ssl: Add config options for OCSP: SSLOCSPResponderTimeout,
411 SSLOCSPResponseMaxAge, SSLOCSPResponseTimeSkew.
412 [Kaspar Brand <httpd-dev.2011 velox.ch>]
414 *) mod_ssl: Revamp output buffering to reduce network overhead for
415 output fragmented into many buckets, such as chunked HTTP responses.
418 *) core: Apply <If> sections to all requests, not only to file base requests.
419 Allow to use <If> inside <Directory>, <Location>, and <Files> sections.
420 The merging of <If> sections now happens after the merging of <Location>
421 sections, even if an <If> section is embedded inside a <Directory> or
422 <Files> section. [Stefan Fritsch]
424 *) mod_proxy: Refactor usage of shared data by dropping the scoreboard
425 and using slotmem. Create foundation for dynamic growth/changes of
426 members within a balancer. Remove BalancerNonce in favor of a
427 per-balancer 'nonce' parameter. [Jim Jagielski]
429 *) mod_status: Don't show slots which are disabled by MaxClients as open.
430 PR: 47022 [Jordi Prats <jordi prats gmail com>, Stefan Fritsch]

435 *) mod_authz_core: Fix bug in merging logic if user-based and non-user-based
436 authorization directives were mixed. [Stefan Fritsch]
438 *) mod_authn_socache: change directive name from AuthnCacheProvider
439 to AuthnCacheProvideFor. The term "provider" is overloaded in
440 this module, and we should avoid confusion between the provider
441 of a backend (AuthnCacheSOCache) and the authn provider(s) for
442 which this module provides cacheing (AuthnCacheProvideFor).
445 *) mod_proxy_http: Allocate the fake backend request from a child pool
446 of the backend connection, instead of misusing the pool of the frontend
447 request. Fixes a thread safety issue where buckets set aside in the
448 backend connection leak into other threads, and then disappear when
449 the frontend request is cleaned up, in turn causing corrupted buckets
450 to make other threads spin. [Graham Leggett]
452 *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables
453 to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and
454 escape other special characters with backslashes. The old format can
455 still be used with the LegacyDNStringFormat argument to SSLOptions.
457 *) core, mod_rewrite: Make the REQUEST_SCHEME variable available to
458 scripts and mod_rewrite. [Stefan Fritsch]
460 *) mod_rewrite: Allow to use arbitrary boolean expressions (ap_expr) in
461 RewriteCond. [Stefan Fritsch]
463 *) mod_rewrite: Allow to unset environment variables using E=!VAR.
464 PR 49512. [Mark Drayton <mark markdrayton info>, Stefan Fritsch]
466 *) mod_headers: Restore the 2.3.8 and earlier default for the first
467 argument of the Header directive ("onsuccess"). [Eric Covener]
469 *) core: Disallow the mixing of relative and absolute Options PR 33708.
470 [Sönke Tesch <st kino-fahrplan.de>]
472 *) core: When exporting request headers to HTTP_* environment variables,
473 drop variables whose names contain invalid characters. Describe in the
474 docs how to restore the old behaviour. [Malte S. Stretz <mss apache org>]
476 *) core: When selecting an IP-based virtual host, favor an exact match for
477 the port over a wildcard (or omitted) port instead of favoring the one
478 that came first in the configuration file. [Eric Covener]
480 *) core: Overlapping virtual host address/port combinations now implicitly
481 enable name-based virtual hosting for that address. The NameVirtualHost
482 directive has no effect, and _default_ is interpreted the same as "*".
485 *) core: In the absence of any Options directives, the default is now
486 "FollowSymlinks" instead of "All". [Igor Galić]
488 *) rotatelogs: Add -e option to write logs through to stdout for optional
489 further processing. [Graham Leggett]
491 *) mod_ssl: Correctly read full lines in input filter when the line is
492 incomplete during first read. PR 50481. [Ruediger Pluem]
494 *) mod_authz_core: Add AuthzSendForbiddenOnFailure directive to allow
495 sending '403 FORBIDDEN' instead of '401 UNAUTHORIZED' if authorization
496 fails for an authenticated user. PR 40721. [Stefan Fritsch]
498 Changes with Apache 2.3.10
500 *) mod_rewrite: Don't implicitly URL-escape the original query string
501 when no substitution has changed it. PR 50447. [Eric Covener]
503 *) core: Honor 'AcceptPathInfo OFF' during internal redirects,
504 such as per-directory mod_rewrite substitutions. PR 50349.
507 *) mod_rewrite: Add 'RewriteOptions InheritBefore' to put the base
508 rules/conditions before the overridden rules/conditions. PR 39313.
509 [Jérôme Grandjanny <jerome.grandjanny cea.fr>]
511 *) mod_autoindex: add IndexIgnoreReset to reset the list of IndexIgnored

523 to UserDir directive, leaving enable/disable of userlists unmerged.

526 *) httpd: When no -k option is provided on the httpd command line, the server
527 was starting without checking for an existing pidfile. PR 50350

531 backend fails. PR 50332.
532 [Daniel Ruggeri <DRuggeri primary.net>, Ruediger Pluem]
534 *) mod_cache_disk: Fix Windows build which was broken after renaming
535 the module. [Gregg L. Smith]

540 Fix a denial of service attack against mod_reqtimeout.
543 *) mod_headers: Change default first argument of Header directive
544 from "onsuccess" to "always". [Eric Covener]
546 *) mod_include: Add the onerror attribute to the include element,
547 allowing an URL to be specified to include on error. [Graham
550 *) mod_cache_disk: mod_disk_cache renamed to mod_cache_disk, to be
551 consistent with the naming of other modules. [Graham Leggett]
553 *) mod_setenvif: Add SetEnvIfExpr directive to set env var depending on
554 expression. [Stefan Fritsch]
556 *) mod_proxy: Fix ProxyPassInterpolateEnv directive. PR 50292.
559 *) suEXEC: Add Suexec directive to disable suEXEC without renaming the
560 binary (Suexec Off), or force startup failure if suEXEC is required
561 but not supported (Suexec On). Change SuexecUserGroup to fail
562 startup instead of just printing a warning if suEXEC is disabled.
565 *) core: Add Error directive for aborting startup or htaccess processing
566 with a specified error message. [Jeff Trawick]
568 *) mod_rewrite: Fix the RewriteEngine directive to work within a
569 location. Previously, once RewriteEngine was switched on globally,
570 it was impossible to switch off. [Graham Leggett]
572 *) core, mod_include, mod_ssl: Move the expression parser derived from
573 mod_include back into mod_include. Replace ap_expr with a parser
574 derived from mod_ssl's parser. Make mod_ssl use the new parser. Rework
575 ap_expr's public interface and provide hooks for modules to add variables
576 and functions. [Stefan Fritsch]
578 *) core: Do the hook sorting earlier so that the hooks are properly sorted
579 for the pre_config hook and during parsing the config. [Stefan Fritsch]
581 *) core: In the absence of any AllowOverride directives, the default is now

740 *) mod_cache: Add a discrete commit_entity() provider function within the
741 mod_cache provider interface which is called to indicate to the
742 provider that caching is complete, giving the provider the opportunity
743 to commit temporary files permanently to the cache in an atomic
744 fashion. Replace the inconsistent use of error cleanups with a formal
745 set of pool cleanups attached to a subpool, which is destroyed on error.
748 *) mod_cache: Change the signature of the store_body() provider function
749 within the mod_cache provider interface to support an "in" brigade
750 and an "out" brigade instead of just a single input brigade. This
751 gives a cache provider the option to consume only part of the brigade
752 passed to it, rather than the whole brigade as was required before.
753 This fixes an out of memory and a request timeout condition that would
754 occur when the original document was a large file. Introduce
755 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
756 the amount of data to attempt to cache at a time. [Graham Leggett]

765 *) mod_cache: Check the request to determine whether we are allowed
766 to return cached content at all, and respect a "Cache-Control:
767 no-cache" header from a client. Previously, "no-cache" would
768 behave like "max-age=0". [Graham Leggett]

1676 so that other modules can load balance traffic as needed. [Paul Querna]
1678 *) mod_heartbeat: New module to generate multicast heartbeats to know if a
1679 server is online. [Paul Querna]
1681 *) mod_buffer: Honour the flush bucket and flush the buffer in the
1682 input filter. Make sure that metadata buckets are written to
1683 the buffer, not to the final brigade. [Graham Leggett]
1685 *) mod_buffer: Optimise the buffering of heap buckets when the heap
1686 buckets stay exactly APR_BUCKET_BUFF_SIZE long. [Graham Leggett,
1689 *) mod_buffer: Optional support for buffering of the input and output
1690 filter stacks. Can collapse many small buckets into fewer larger
1691 buckets, and prevents excessively small chunks being sent over
1692 the wire. [Graham Leggett]
1694 *) mod_privileges: new module to make httpd on Solaris privileges-aware
1695 and to enable different virtualhosts to run with different
1696 privileges and Unix user/group IDs [Nick Kew]
1698 *) mod_mem_cache: this module has been removed. [William Rowe]
1700 *) authn/z: Remove mod_authn_default and mod_authz_default.
1703 *) authz: Fix handling of authz configurations, make default authz
1704 logic replicate 2.2.x authz logic, and replace <Satisfy*>, Reject,
1705 and AuthzMergeRules directives with Match, <Match*>, and AuthzMerge
1706 directives. [Chris Darroch]
1708 *) mod_authn_core: Prevent crash when provider alias created to
1709 provider which is not yet registered. [Chris Darroch]
1711 *) mod_authn_core: Add AuthType of None to support disabling
1712 authentication. [Chris Darroch]

1715 constrain their use to conform with that of other access control
1716 and authorization directives. [Chris Darroch]

1745 within the output headers and error output headers, so that the
1746 session is maintained across redirects. [Graham Leggett]

1749 after a form login. Fixes a missing REMOTE_USER variable directly
1750 following a login. [Graham Leggett]

1753 included in the blank cookie when cookies are removed. This fixes an
1754 inability to log out when using mod_auth_form. [Graham Leggett]
1756 *) mod_session: Prevent a segfault when a CGI script sets a cookie with a
1757 null value. [David Shane Holden <dpejesh apache.org>]
1759 *) core, authn/z: Determine registered authn/z providers directly in
1760 ap_setup_auth_internal(), which allows optional functions that just
1761 wrapped ap_list_provider_names() to be removed from authn/z modules.
1764 *) authn/z: Convert common provider version strings to macros.
1767 *) core: When testing for slash-terminated configuration paths in
1768 ap_location_walk(), don't look past the start of an empty string
1769 such as that created by a <Location ""> directive.
1772 *) core, mod_proxy: If a kept_body is present, it becomes safe for
1773 subrequests to support message bodies. Make sure that safety
1774 checks within the core and within the proxy are not triggered
1775 when kept_body is present. This makes it possible to embed
1776 proxied POST requests within mod_include. [Graham Leggett]
1778 *) mod_auth_form: Make sure the input filter stack is properly set
1779 up before reading the login form. Make sure the kept body filter
1780 is correctly inserted to ensure the body can be read a second
1781 time safely should the authn be successful. [Graham Leggett,

1785 hook instead of during fixups. Add a safety check to ensure the
1786 filters cannot be inserted more than once. [Graham Leggett,

1794 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
1795 for both in- and out-put headers; and replace it by a single
1796 ap_cache_cacheable_headers() wrapped in a in- and out-put
1797 specific ap_cache_cacheable_headers_in()/out(). The latter
1798 which will also merge error and ensure content-type. To keep
1799 cache modules consistent with ease. This API change bumps
1800 up the minor MM by one [Dirk-Willem van Gulik].
1802 *) Move the KeptBodySize directive, kept_body filters and the
1803 ap_parse_request_body function out of the http module and into a
1804 new module called mod_request, reducing the size of the core.
1807 *) mod_dbd: Handle integer configuration directive parameters with a
1810 *) Change the directives within the mod_session* modules to be valid

1812 suggested by wrowe. [Graham Leggett]
1814 *) mod_auth_form: Add a module capable of allowing end users to log
1815 in using an HTML form, storing the credentials within mod_session.
1818 *) Add a function to the http filters that is able to parse an HTML
1819 form request with the type of application/x-www-form-urlencoded.
1822 *) mod_session_crypto: Initialise SSL in the post config hook.
1823 [Ruediger Pluem, Graham Leggett]
1825 *) mod_session_dbd: Add a session implementation capable of storing
1826 session information in a SQL database via the dbd interface. Useful
1827 for sites where session privacy is important. [Graham Leggett]

1830 of encrypting and decrypting sessions wherever they may be stored.
1831 Introduces a level of privacy when sessions are stored on the
1832 browser. [Graham Leggett]
1834 *) mod_session_cookie: Add a session implementation capable of storing
1835 session information within cookies on the browser. Useful for high
1836 volume sites where server bound sessions are too resource intensive.
1839 *) mod_session: Add a generic session interface to unify the different
1840 attempts at saving persistent sessions across requests.
1843 *) core, authn/z: Avoid calling access control hooks for internal requests
1844 with configurations which match those of initial request. Revert to
1845 original behaviour (call access control hooks for internal requests
1846 with URIs different from initial request) if any access control hooks or
1847 providers are not registered as permitting this optimization.
