580 *) core, authn/z: Avoid calling access control hooks for internal requests
581 with configurations which match those of initial request. Revert to
582 original behaviour (call access control hooks for internal requests
583 with URIs different from initial request) if any access control hooks or
584 providers are not registered as permitting this optimization.
585 Introduce wrappers for access control hook and provider registration
586 which can accept additional mode and flag data. [Chris Darroch]
588 *) Introduced ap_expr API for expression evaluation.
589 This is adapted from mod_include, which is the first module
593 *) mod_authz_dbd: When redirecting after successful login/logout per
594 AuthzDBDRedirectQuery, do not report authorization failure, and use
595 first row returned by database query instead of last row.
598 *) mod_ldap: Correctly return all requested attribute values
599 when some attributes have a null value.

610 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]

614 third party module authors. PR 42431 [Dirk-Willem van Gulik].
616 *) mod_dir, mod_negotiation: pass the output filter information
617 to newly created sub requests; as these are later on used
618 as true requests with an internal redirect. This allows for
619 mod_cache et.al. to trap the results of the redirect.
620 [Dirk-Willem van Gulik, Ruediger Pluem]
622 *) mod_ldap: Add support (taking advantage of the new APR capability)
623 for ldap rebind callback while chasing referrals. This allows direct
624 searches on LDAP servers (in particular MS Active Directory 2003+)
625 using referrals without the use of the global catalog.

645 to shtml files can be passed through to embedded scripts as POST

700 location parameter, ala SSLMutex. [Jim Jagielski]
702 *) mod_authn_dbd: Export any additional columns queried in the SQL select
703 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
704 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
706 *) mod_dbd: Key the storage of prepared statements on the hex string
707 value of server_rec, rather than the server name, as the server name
708 may change (eg when the server name is set) at any time, causing
709 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]

726 directive values and adjust them while messages can still be logged

735 The return value is index to the signaled thread in the
736 creted_threads array. We can not use WAIT_TIMEOUT because
737 his value is defined as 258, thus limiting the MaxThreads
738 to that value. [Mladen Turk]
740 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir

782 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
783 into mod_authn_core. [Brad Nicholes]
785 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'

787 support for these directives.
790 *) Authz: Move the 'Require' directive from the core module as well as
791 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
792 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
793 logic into the authorization processing. [Brad Nicholes]
795 *) Authz: Add the new module mod_authz_core which acts as the
796 authorization provider vector and contains common authz
797 directives. [Brad Nicholes]
799 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
800 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
802 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle

818 *) Asynchronous write completion for the Event MPM. [Brian Pane]
820 *) Added an End-Of-Request bucket type. The logging of a request and
821 the freeing of its pool are now done when the EOR bucket is destroyed.
822 This has the effect of delaying the logging until right after the last
823 of the response is sent; ap_core_output_filter() calls the access logger
824 indirectly when it destroys the EOR bucket. [Brian Pane]
826 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
827 and the format of statistical output has changed. [Colm MacCarthaigh]
829 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
