34 PR 46830. [Dan Poirier]
36 *) mod_ssl: Check SNI hostname against Host header case-insensitively.
37 PR 49491. [Mayank Agrawal <magrawal.08 gmail.com>]
39 *) mod_ldap: Add LDAPConnectionPoolTTL to give control over lifetime
40 of bound backend LDAP connections. PR47634 [Eric Covener]
42 *) mod_cache: Make CacheEnable and CacheDisable configurable per
43 directory in addition to per server, making them work from within
44 a LocationMatch. [Graham Leggett]
46 *) worker, event, prefork: Correct several issues when built as
47 DSOs; most notably, the scoreboard was reinitialized during graceful
48 restart, such that processes of the previous generation were not
49 observable. [Jeff Trawick]
51 Changes with Apache 2.3.11
53 *) mod_proxy: balancer-manager now uses POST instead of GET.
56 *) core: new util function: ap_parse_form_data(). Previously,
57 this capability was tucked away in mod_request. [Jim Jagielski]
59 *) core: new hook: ap_run_pre_read_request. [Jim Jagielski]
61 *) mod_cache: When a request other than GET or HEAD arrives, we must
62 invalidate existing cache entities as per RFC2616 13.10. PR 15868.
65 *) modules: Fix many modules that were not correctly initializing if they
66 were not active during server startup but got enabled later during a
67 graceful restart. [Stefan Fritsch]
69 *) core: Create new ap_state_query function that allows modules to determine
70 if the current configuration run is the initial one at server startup,
71 and if the server is started for testing/config dumping only.
74 *) mod_proxy: Runtime configuration of many parameters for existing
75 balancers via the balancer-manager. [Jim Jagielski]
77 *) mod_proxy: Runtime addition of new workers (BalancerMember) for existing
78 balancers via the balancer-manager. [Jim Jagielski]
80 *) mod_cache: When a bad Expires date is present, we need to behave as if
81 the Expires is in the past, not as if the Expires is missing. PR 16521.
82 [Co-Advisor <coad@measurement-factory.com>]

85 Cache-Control header. PR 50199. [Graham Leggett]
87 *) mod_dav: Revert change to send 501 error if unknown Content-* header is
88 received for a PUT request. PR 42978. [Stefan Fritsch]

91 take precedence if present. PR 35247. [Graham Leggett]
93 *) mod_ssl: Fix a possible startup failure if multiple SSL vhosts
94 are configured with the same ServerName and private key file.
95 [Masahiro Matsuya <mmatsuya redhat.com>, Joe Orton]

104 PR 50434 [Stefan Fritsch]
106 *) core: Add support to set variables with the 'Define' directive. The
107 variables that can then be used in the config using the ${VAR} syntax
108 known from envvar interpolation. [Stefan Fritsch]
110 *) mod_proxy_http: make adding of X-Forwarded-* headers configurable.
111 ProxyAddHeaders defaults to On. [Vincent Deffontaines]
113 *) mod_slotmem_shm: Increase memory alignment for slotmem data.

117 SSLOCSPResponseMaxAge, SSLOCSPResponseTimeSkew.
118 [Kaspar Brand <httpd-dev.2011 velox.ch>]
120 *) mod_ssl: Revamp output buffering to reduce network overhead for
121 output fragmented into many buckets, such as chunked HTTP responses.
124 *) core: Apply <If> sections to all requests, not only to file base requests.
125 Allow to use <If> inside <Directory>, <Location>, and <Files> sections.
126 The merging of <If> sections now happens after the merging of <Location>
127 sections, even if an <If> section is embedded inside a <Directory> or
128 <Files> section. [Stefan Fritsch]
130 *) mod_proxy: Refactor usage of shared data by dropping the scoreboard
131 and using slotmem. Create foundation for dynamic growth/changes of
132 members within a balancer. Remove BalancerNonce in favor of a
133 per-balancer 'nonce' parameter. [Jim Jagielski]
135 *) mod_status: Don't show slots which are disabled by MaxClients as open.
136 PR: 47022 [Jordi Prats <jordi prats gmail com>, Stefan Fritsch]
138 *) mpm_prefork: Fix ap_mpm_query results for AP_MPMQ_MAX_DAEMONS and
141 *) mod_authz_core: Fix bug in merging logic if user-based and non-user-based
142 authorization directives were mixed. [Stefan Fritsch]
144 *) mod_authn_socache: change directive name from AuthnCacheProvider
145 to AuthnCacheProvideFor. The term "provider" is overloaded in
146 this module, and we should avoid confusion between the provider
147 of a backend (AuthnCacheSOCache) and the authn provider(s) for
148 which this module provides cacheing (AuthnCacheProvideFor).
151 *) mod_proxy_http: Allocate the fake backend request from a child pool
152 of the backend connection, instead of misusing the pool of the frontend
153 request. Fixes a thread safety issue where buckets set aside in the
154 backend connection leak into other threads, and then disappear when
155 the frontend request is cleaned up, in turn causing corrupted buckets
156 to make other threads spin. [Graham Leggett]
158 *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables
159 to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and
160 escape other special characters with backslashes. The old format can
161 still be used with the LegacyDNStringFormat argument to SSLOptions.
163 *) core, mod_rewrite: Make the REQUEST_SCHEME variable available to
164 scripts and mod_rewrite. [Stefan Fritsch]
166 *) mod_rewrite: Allow to use arbitrary boolean expressions (ap_expr) in
167 RewriteCond. [Stefan Fritsch]
169 *) mod_rewrite: Allow to unset environment variables using E=!VAR.
170 PR 49512. [Mark Drayton <mark markdrayton info>, Stefan Fritsch]
172 *) mod_headers: Restore the 2.3.8 and earlier default for the first
173 argument of the Header directive ("onsuccess"). [Eric Covener]
175 *) core: Disallow the mixing of relative and absolute Options PR 33708.
176 [Sönke Tesch <st kino-fahrplan.de>]
178 *) core: When exporting request headers to HTTP_* environment variables,
179 drop variables whose names contain invalid characters. Describe in the
180 docs how to restore the old behaviour. [Malte S. Stretz <mss apache org>]
182 *) core: When selecting an IP-based virtual host, favor an exact match for
183 the port over a wildcard (or omitted) port instead of favoring the one
184 that came first in the configuration file. [Eric Covener]
186 *) core: Overlapping virtual host address/port combinations now implicitly
187 enable name-based virtual hosting for that address. The NameVirtualHost
188 directive has no effect, and _default_ is interpreted the same as "*".
191 *) core: In the absence of any Options directives, the default is now
192 "FollowSymlinks" instead of "All". [Igor Galić]
194 *) rotatelogs: Add -e option to write logs through to stdout for optional
195 further processing. [Graham Leggett]
197 *) mod_ssl: Correctly read full lines in input filter when the line is
198 incomplete during first read. PR 50481. [Ruediger Pluem]
200 *) mod_authz_core: Add AuthzSendForbiddenOnFailure directive to allow
201 sending '403 FORBIDDEN' instead of '401 UNAUTHORIZED' if authorization
202 fails for an authenticated user. PR 40721. [Stefan Fritsch]
204 Changes with Apache 2.3.10
206 *) mod_rewrite: Don't implicitly URL-escape the original query string
207 when no substitution has changed it. PR 50447. [Eric Covener]
209 *) core: Honor 'AcceptPathInfo OFF' during internal redirects,
210 such as per-directory mod_rewrite substitutions. PR 50349.
213 *) mod_rewrite: Add 'RewriteOptions InheritBefore' to put the base
214 rules/conditions before the overridden rules/conditions. PR 39313.
215 [Jérôme Grandjanny <jerome.grandjanny cea.fr>]
217 *) mod_autoindex: add IndexIgnoreReset to reset the list of IndexIgnored
218 filenames in higher precedence configuration sections. PR 24243.
221 *) mod_cgid: RLimit* directive support for mod_cgid. PR 42135
224 *) core: Fail startup when the argument to ServerName looks like a glob
225 or a regular expression instead of a hostname (*?[]). PR 39863
226 [Rahul Nair <rahul.g.nair gmail.com>]
228 *) mod_userdir: Add merging of enable, disable, and filename arguments
229 to UserDir directive, leaving enable/disable of userlists unmerged.
230 PR 44076 [Eric Covener]
232 *) httpd: When no -k option is provided on the httpd command line, the server
233 was starting without checking for an existing pidfile. PR 50350
236 *) mod_proxy: Put the worker in error state if the SSL handshake with the
237 backend fails. PR 50332.
238 [Daniel Ruggeri <DRuggeri primary.net>, Ruediger Pluem]
240 *) mod_cache_disk: Fix Windows build which was broken after renaming
241 the module. [Gregg L. Smith]
243 Changes with Apache 2.3.9
245 *) SECURITY: CVE-2010-1623 (cve.mitre.org)
246 Fix a denial of service attack against mod_reqtimeout.
249 *) mod_headers: Change default first argument of Header directive
250 from "onsuccess" to "always". [Eric Covener]
252 *) mod_include: Add the onerror attribute to the include element,
253 allowing an URL to be specified to include on error. [Graham
256 *) mod_cache_disk: mod_disk_cache renamed to mod_cache_disk, to be
257 consistent with the naming of other modules. [Graham Leggett]
259 *) mod_setenvif: Add SetEnvIfExpr directive to set env var depending on
260 expression. [Stefan Fritsch]
262 *) mod_proxy: Fix ProxyPassInterpolateEnv directive. PR 50292.
265 *) suEXEC: Add Suexec directive to disable suEXEC without renaming the
266 binary (Suexec Off), or force startup failure if suEXEC is required
267 but not supported (Suexec On). Change SuexecUserGroup to fail
268 startup instead of just printing a warning if suEXEC is disabled.
271 *) core: Add Error directive for aborting startup or htaccess processing
272 with a specified error message. [Jeff Trawick]
274 *) mod_rewrite: Fix the RewriteEngine directive to work within a
275 location. Previously, once RewriteEngine was switched on globally,
276 it was impossible to switch off. [Graham Leggett]
278 *) core, mod_include, mod_ssl: Move the expression parser derived from
279 mod_include back into mod_include. Replace ap_expr with a parser
280 derived from mod_ssl's parser. Make mod_ssl use the new parser. Rework
281 ap_expr's public interface and provide hooks for modules to add variables
282 and functions. [Stefan Fritsch]
284 *) core: Do the hook sorting earlier so that the hooks are properly sorted
285 for the pre_config hook and during parsing the config. [Stefan Fritsch]
287 *) core: In the absence of any AllowOverride directives, the default is now
288 "None" instead of "All". PR49823 [Eric Covener]
290 *) mod_proxy: Don't allow ProxyPass or ProxyPassReverse in
291 <Directory> or <Files>. PR47765 [Eric Covener]
293 *) prefork/worker/event MPMS: default value (when no directive is present)
294 of MaxConnectionsPerChild/MaxRequestsPerChild is changed to 0 from 10000
295 to match default configuration and manual. PR47782 [Eric Covener]
297 *) proxy_connect: Don't give up in the middle of a CONNECT tunnel
298 when the child process is starting to exit. PR50220. [Eric Covener]
300 *) mod_autoindex: Fix inheritance of mod_autoindex directives into
301 contexts that don't have any mod_autoindex directives. PR47766.
304 *) mod_rewrite: Add END flag for RewriteRule to prevent further rounds
305 of rewrite processing when a per-directory substitution occurs.
308 *) mod_ssl: Make sure to always log an error if loading of CA certificates
309 fails. PR 40312. [Paul Tiemann <issues apache org ourdetour com>]
311 *) mod_dav: Send 501 error if unknown Content-* header is received for a PUT
312 request (RFC 2616 9.6). PR 42978. [Stefan Fritsch]
314 *) mod_dav: Send 400 error if malformed Content-Range header is received for
315 a put request (RFC 2616 14.16). PR 49825. [Stefan Fritsch]
317 *) mod_proxy: Release the backend connection as soon as EOS is detected,
318 so the backend isn't forced to wait for the client to eventually
319 acknowledge the data. [Graham Leggett]
321 *) mod_proxy: Optimise ProxyPass within a Location so that it is stored
322 per-directory, and chosen during the location walk. Make ProxyPass
323 work correctly from within a LocationMatch. [Graham Leggett]
325 *) core: Fix segfault if per-module LogLevel is on virtual host
326 scope. PR 50117. [Stefan Fritsch]
328 *) mod_proxy: Move the ProxyErrorOverride directive to have per
329 directory scope. [Graham Leggett]
331 *) mod_allowmethods: New module to deny certain HTTP methods without
332 interfering with authentication/authorization. [Paul Querna,
333 Igor Galić, Stefan Fritsch]
335 *) mod_ssl: Log certificate information and improve error message if client
336 cert verification fails. PR 50093, PR 50094. [Lassi Tuura <lat cern ch>,
339 *) htcacheclean: Teach htcacheclean to limit cache size by number of
340 inodes in addition to size of files. Prevents a cache disk from
341 running out of space when many small files are cached.
344 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
345 describes more accurately what the directive does. The old name
346 still works but logs a warning. [Stefan Fritsch]
348 *) mod_cache: Optionally serve stale data when a revalidation returns a
349 5xx response, controlled by the CacheStaleOnError directive.
352 *) htcacheclean: Allow the listing of valid URLs within the cache, with
353 the option to list entry metadata such as sizes and times. [Graham
356 *) mod_cache: correctly parse quoted strings in cache headers.
359 *) mod_cache: Allow control over the base URL of reverse proxied requests
360 using the CacheKeyBaseURL directive, so that the cache key can be
361 calculated from the endpoint URL instead of the server URL. [Graham
364 *) mod_cache: CacheLastModifiedFactor, CacheStoreNoStore, CacheStorePrivate,
365 CacheStoreExpired, CacheIgnoreNoLastMod, CacheDefaultExpire,
366 CacheMinExpire and CacheMaxExpire can be set per directory/location.
369 *) mod_disk_cache: CacheMaxFileSize, CacheMinFileSize, CacheReadSize and
370 CacheReadTime can be set per directory/location. [Graham Leggett]
372 *) core: Speed up config parsing if using a very large number of config
373 files. PR 50002 [andrew cloudaccess net]
375 *) mod_cache: Support the caching of HEAD requests. [Graham Leggett]
377 *) htcacheclean: Allow the option to round up file sizes to a given
378 block size, improving the accuracy of disk usage. [Graham Leggett]
380 *) mod_ssl: Add authz providers for use with mod_authz_core and its
381 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
382 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
383 'ssl-require' (expressions with same syntax as SSLRequire).
386 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
387 bison instead of yacc. [Stefan Fritsch]
389 *) mod_disk_cache: Change on-disk header file format to support the
390 link of the device/inode of the data file to the matching header
391 file, and to support the option of not writing a data file when
392 the data file is empty. [Graham Leggett]
394 *) core/mod_unique_id: Add generate_log_id hook to allow to use
395 the ID generated by mod_unique_id as error log ID for requests.
398 *) mod_cache: Make sure that we never allow a 304 Not Modified response
399 that we asked for to leak to the client should the 304 response be
400 uncacheable. PR45341 [Graham Leggett]
402 *) mod_cache: Add the cache_status hook to register the final cache
403 decision hit/miss/revalidate. Add optional support for an X-Cache
404 and/or an X-Cache-Detail header to add the cache status to the
405 response. PR48241 [Graham Leggett]
407 *) mod_authz_host: Add 'local' provider that matches connections originating
408 on the local host. PR 19938. [Stefan Fritsch]
410 *) Event MPM: Fix crash accessing pollset on worker thread when child
411 process is exiting. [Jeff Trawick]
413 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
414 pass the system library path (LD_LIBRARY_PATH or platform-specific
415 variables) along with the system PATH, by default. Both should be
416 overridden together as desired using PassEnv etc; see mod_env.
419 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
420 capture a stale backend response, perform If-Modified-Since requests
421 against the backend, and serving from the cache all 304 responses.
422 This restores pre-2.2.4 cache behavior. [William Rowe]
424 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
425 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
426 the ambiguity of the symlink test "-ltest", introduce -h or -L as
427 symlink test operators. [William Rowe]
429 *) mod_cache: Give the cache provider the opportunity to choose to cache
430 or not cache based on the buckets present in the brigade, such as the
431 presence of a FILE bucket.
434 *) mod_authz_core: Allow authz providers to check args while reading the
435 config and allow to cache parsed args. Move 'all' and 'env' authz
436 providers from mod_authz_host to mod_authz_core. Add 'method' authz
437 provider depending on the HTTP method. [Stefan Fritsch]
439 *) mod_include: Move the request_rec within mod_include to be
440 exposed within include_ctx_t. [Graham Leggett]
442 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
443 variable being echoed or set to be decoded and then encoded as separate
444 steps. PR47686 [Graham Leggett]
446 *) mod_cache: Add a discrete commit_entity() provider function within the
447 mod_cache provider interface which is called to indicate to the
448 provider that caching is complete, giving the provider the opportunity
449 to commit temporary files permanently to the cache in an atomic
450 fashion. Replace the inconsistent use of error cleanups with a formal
451 set of pool cleanups attached to a subpool, which is destroyed on error.
454 *) mod_cache: Change the signature of the store_body() provider function
455 within the mod_cache provider interface to support an "in" brigade
456 and an "out" brigade instead of just a single input brigade. This
457 gives a cache provider the option to consume only part of the brigade
458 passed to it, rather than the whole brigade as was required before.
459 This fixes an out of memory and a request timeout condition that would
460 occur when the original document was a large file. Introduce
461 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
462 the amount of data to attempt to cache at a time. [Graham Leggett]
464 *) core: Add ErrorLogFormat to allow configuring error log format, including
465 additional information that is logged once per connection or request. Add
466 error log IDs for connections and request to allow correlating error log
467 lines and the corresponding access log entry. [Stefan Fritsch]
469 *) core: Disable sendfile by default. [Stefan Fritsch]
471 *) mod_cache: Check the request to determine whether we are allowed
472 to return cached content at all, and respect a "Cache-Control:
473 no-cache" header from a client. Previously, "no-cache" would
474 behave like "max-age=0". [Graham Leggett]
476 *) mod_cache: Use a proper filter context to hold filter data instead
477 of misusing the per-request configuration. Fixes a segfault on trunk
478 when the normal handler is used. [Graham Leggett]
480 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
481 it is too long. PR 49388. [Stefan Fritsch]
483 *) vhosts: Do not allow _default_ in NameVirtualHost, or mixing *
484 and non-* ports on NameVirtualHost, or multiple NameVirtualHost
485 directives for the same address:port, or NameVirtualHost
486 directives with no matching VirtualHosts, or multiple ip-based
487 VirtualHost sections for the same address:port. These were
488 previously accepted with a warning, but the behavior was
489 undefined. [Dan Poirier]
491 *) mod_remoteip: Fix a segfault when using mod_remoteip in conjunction with
492 Allow/Deny. PR 49838. [Andrew Skalski <voltara gmail.com>]
494 *) core: DirectoryMatch can now match on the end of line character ($),
495 and sub-directories of matched directories are no longer implicitly
496 matched. PR49809 [Eric Covener]

1672 bucket and barfs. The fix is to pass a bucket rather than a brigade.
1673 [Niklas Edmundsson <nikke acc.umu.se>]
1675 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
1677 *) ap_get_server_version() has been removed. Third-party modules must
1678 now use ap_get_server_banner() or ap_get_server_description().
1681 *) All MPMs: Introduce a check_config phase between pre_config and
1682 open_logs, to allow modules to review interdependent configuration
1683 directive values and adjust them while messages can still be logged
1684 to the console. Handle relevant MPM directives during this phase
1685 and format messages for both the console and the error log, as
1686 appropriate. [Chris Darroch]
1688 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
1689 to circumvent the symbolic link checks imposed by FollowSymLinks and
1690 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
1692 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
1693 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
1694 The default is none as this is far greater debugging resolution than
1695 the typical administrator is prepared to untangle. [William Rowe]
1697 *) mod_disk_cache: If possible, check if the size of an object to cache is
1698 within the configured boundaries before actually saving data.
1699 [Niklas Edmundsson <nikke acc.umu.se>]
1701 *) Worker and event MPMs: Remove improper scoreboard updates which were
1702 performed in the event of a fork() failure. [Chris Darroch]
1704 *) Add support for fcgi:// proxies to mod_rewrite.
1705 [Markus Schiegl <ms schiegl.com>]
1707 *) Remove incorrect comments from scoreboard.h regarding conditional
1708 loading of worker_score structure with mod_status, and remove unused
1709 definitions relating to old life_status field.
1710 [Chris Darroch <chrisd pearsoncmg.com>]
1712 *) Remove allocation of memory for unused array of lb_score pointers
1713 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
1715 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
1716 [Garrett Rooney, Jim Jagielski, Paul Querna]
1718 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
1719 [Chris Darroch <chrisd pearsoncmg.com>]
1721 *) mod_charset_lite: Remove Content-Length when output filter can
1722 invalidate it. Warn when input filter can invalidate it.
1725 *) Authz: Add the new module mod_authn_core that will provide common
1726 authn directives such as 'AuthType', 'AuthName'. Move the directives
1727 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
1728 into mod_authn_core. [Brad Nicholes]
1730 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
1731 into the new module mod_access_compat which can be loaded to provide
1732 support for these directives.
1735 *) Authz: Move the 'Require' directive from the core module as well as
1736 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
1737 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
1738 logic into the authorization processing. [Brad Nicholes]
1740 *) Authz: Add the new module mod_authz_core which acts as the
1741 authorization provider vector and contains common authz
1742 directives. [Brad Nicholes]
1744 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
1745 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
1747 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
1748 host-based access control provided by mod_authz_host and invoked
1749 through the 'Require' directive. [Brad Nicholes]
1751 *) Authz: Convert all of the authz modules from hook based to
1752 provider based. [Brad Nicholes]
1754 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
1755 seconds to cache a document.
1756 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
1758 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
1760 *) Fix typo in ProxyStatus syntax error message.
1761 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
1763 *) Asynchronous write completion for the Event MPM. [Brian Pane]
1765 *) Added an End-Of-Request bucket type. The logging of a request and
1766 the freeing of its pool are now done when the EOR bucket is destroyed.
1767 This has the effect of delaying the logging until right after the last
1768 of the response is sent; ap_core_output_filter() calls the access logger
1769 indirectly when it destroys the EOR bucket. [Brian Pane]
1771 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
1772 and the format of statistical output has changed. [Colm MacCarthaigh]
1774 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
1776 *) Added new connection states for handler and write completion
1779 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
1782 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
1783 allowing string-valued client certificate attributes to be used for
1784 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
