included in the blank cookie when cookies are removed. This fixes an
inability to log out when using mod_auth_form. [Graham Leggett]

null value. [David Shane Holden <dpejesh apache.org>]

*) core, authn/z: Determine registered authn/z providers directly in
ap_setup_auth_internal(), which allows optional functions that just
wrapped ap_list_provider_names() to be removed from authn/z modules.
[Chris Darroch]
*) authn/z: Convert common provider version strings to macros.
*) core: When testing for slash-terminated configuration paths in
ap_location_walk(), don't look past the start of an empty string
such as that created by a <Location ""> directive.
[Chris Darroch]
*) core, mod_proxy: If a kept_body is present, it becomes safe for
subrequests to support message bodies. Make sure that safety
checks within the core and within the proxy are not triggered
when kept_body is present. This makes it possible to embed
proxied POST requests within mod_include. [Graham Leggett]
*) mod_auth_form: Make sure the input filter stack is properly set
up before reading the login form. Make sure the kept body filter
is correctly inserted to ensure the body can be read a second
time safely should the authn be successful. [Graham Leggett,

merging in the actual entity headers and doing normal
hop-by-hop cleansing. [Dirk-Willem van Gulik].
*) cache: retire ap_cache_cacheable_hdrs_out() which was used
for both in- and out-put headers; and replace it by a single
ap_cache_cacheable_headers() wrapped in a in- and out-put
specific ap_cache_cacheable_headers_in()/out(). The latter
which will also merge error and ensure content-type. To keep
cache modules consistent with ease. This API change bumps
up the minor MM by one [Dirk-Willem van Gulik].
*) Move the KeptBodySize directive, kept_body filters and the
ap_parse_request_body function out of the http module and into a
new module called mod_request, reducing the size of the core.
[Graham Leggett]
*) mod_dbd: Handle integer configuration directive parameters with a
dedicated function.
*) Change the directives within the mod_session* modules to be valid
both inside and outside the location/directory sections, as
suggested by wrowe. [Graham Leggett]
*) mod_auth_form: Add a module capable of allowing end users to log
in using an HTML form, storing the credentials within mod_session.
[Graham Leggett]
*) Add a function to the http filters that is able to parse an HTML
form request with the type of application/x-www-form-urlencoded.
[Graham Leggett]
*) mod_session_crypto: Initialise SSL in the post config hook.
[Ruediger Pluem, Graham Leggett]
*) mod_session_dbd: Add a session implementation capable of storing
session information in a SQL database via the dbd interface. Useful
for sites where session privacy is important. [Graham Leggett]
*) mod_session_crypto: Add a session encoding implementation capable
of encrypting and decrypting sessions wherever they may be stored.
Introduces a level of privacy when sessions are stored on the
browser. [Graham Leggett]
*) mod_session_cookie: Add a session implementation capable of storing
session information within cookies on the browser. Useful for high
volume sites where server bound sessions are too resource intensive.
[Graham Leggett]
*) mod_session: Add a generic session interface to unify the different
attempts at saving persistent sessions across requests.
[Graham Leggett]
*) core, authn/z: Avoid calling access control hooks for internal requests
with configurations which match those of initial request. Revert to
original behaviour (call access control hooks for internal requests
with URIs different from initial request) if any access control hooks or
providers are not registered as permitting this optimization.
Introduce wrappers for access control hook and provider registration
which can accept additional mode and flag data. [Chris Darroch]
*) Introduced ap_expr API for expression evaluation.
This is adapted from mod_include, which is the first module
to use the new API.
[Nick Kew]
*) mod_authz_dbd: When redirecting after successful login/logout per
AuthzDBDRedirectQuery, do not report authorization failure, and use
first row returned by database query instead of last row.

when some attributes have a null value.

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

value of server_rec, rather than the server name, as the server name
may change (eg when the server name is set) at any time, causing
weird behaviour in modules dependent on mod_dbd. [Graham Leggett]

*) sendfile_nonblocking() takes the _brigade_ as an argument, gets
