574 hop-by-hop cleansing. [Dirk-Willem van Gulik].
576 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
577 for both in- and out-put headers; and replace it by a single
578 ap_cache_cacheable_headers() wrapped in a in- and out-put
579 specific ap_cache_cacheable_headers_in()/out(). The latter
580 which will also merge error and ensure content-type. To keep
581 cache modules consistent with ease. This API change bumps
582 up the minor MM by one [Dirk-Willem van Gulik].

585 PR 44799 [Christian Wenz <christian wenz.org>]
587 *) Move the KeptBodySize directive, kept_body filters and the
588 ap_parse_request_body function out of the http module and into a
589 new module called mod_request, reducing the size of the core.
592 *) mod_dbd: Handle integer configuration directive parameters with a

597 suggested by wrowe. [Graham Leggett]
599 *) mod_auth_form: Add a module capable of allowing end users to log
600 in using an HTML form, storing the credentials within mod_session.
603 *) Add a function to the http filters that is able to parse an HTML
604 form request with the type of application/x-www-form-urlencoded.
607 *) mod_session_crypto: Initialise SSL in the post config hook.

610 *) mod_session_dbd: Add a session implementation capable of storing
611 session information in a SQL database via the dbd interface. Useful
612 for sites where session privacy is important. [Graham Leggett]
614 *) mod_session_crypto: Add a session encoding implementation capable
615 of encrypting and decrypting sessions wherever they may be stored.
616 Introduces a level of privacy when sessions are stored on the
617 browser. [Graham Leggett]
619 *) mod_session_cookie: Add a session implementation capable of storing
620 session information within cookies on the browser. Useful for high
621 volume sites where server bound sessions are too resource intensive.
624 *) mod_session: Add a generic session interface to unify the different
625 attempts at saving persistent sessions across requests.
628 *) core, authn/z: Avoid calling access control hooks for internal requests
629 with configurations which match those of initial request. Revert to
630 original behaviour (call access control hooks for internal requests
631 with URIs different from initial request) if any access control hooks or
632 providers are not registered as permitting this optimization.
633 Introduce wrappers for access control hook and provider registration
634 which can accept additional mode and flag data. [Chris Darroch]

642 AuthzDBDRedirectQuery, do not report authorization failure, and use

673 using referrals without the use of the global catalog.

751 into the environment with the name AUTHENTICATE_<COLUMN>. This brings

754 *) mod_dbd: Key the storage of prepared statements on the hex string
755 value of server_rec, rather than the server name, as the server name

839 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
840 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'

868 *) Added an End-Of-Request bucket type. The logging of a request and
869 the freeing of its pool are now done when the EOR bucket is destroyed.
870 This has the effect of delaying the logging until right after the last
871 of the response is sent; ap_core_output_filter() calls the access logger
872 indirectly when it destroys the EOR bucket. [Brian Pane]
