* Sync with 2.2.x CHANGES file

     The default is none as this is far greater debugging resolution than 

     the typical administrator is prepared to untangle.  [William Rowe]

  *) mod_speling: Add directive to deal with case corrections only

     and ignore other misspellings [Olivier Thereaux  <ot w3.org>]

  *) mod_disk_cache: If possible, check if the size of an object to cache is

     within the configured boundaries before actually saving data.

     [Niklas Edmundsson <nikke acc.umu.se>]

     LDAP client SDKs that don't support LDAP_SECURITY_ERROR macro. PR 39529.

     [Ray Price <dohrayme yahoo.com>, Josh Fenlason <jfenlason ptc.com>]

  *) mod_cache: Do not overwrite the Content-Type in the cache, for

     successfully revalidated cached objects. PR 39647. [Ruediger Pluem]

  *) mod_disk_cache: Delete temporary files if they cannot be renamed to their

     final name. [Davi Arnaut <davi haxent.com.br>]

  *) Worker and event MPMs: Remove improper scoreboard updates which were

     performed in the event of a fork() failure.  [Chris Darroch]

  *) mod_cache: Make caching of reverse SSL proxies possible again. PR 39593.

     [Ruediger Pluem, Joe Orton]

  *) Add support for fcgi:// proxies to mod_rewrite.

     [Markus Schiegl <ms schiegl.com>]

  *) Remove allocation of memory for unused array of lb_score pointers

     in ap_init_scoreboard().  [Chris Darroch <chrisd pearsoncmg.com>]

  *) core, mod_http: add optional 'scheme://' prefix to ServerName directive. 

     For 'https', mod_http returns "https" for the ap_hook_http_scheme and

     DEFAULT_HTTPS_PORT for ap_hook_default_port.  This fixes Redirect

     responses to requests for directories without a trailing slash when

     httpd runs behind a proxy or offload device that processes SSL.  It

     also enables support for Subversion in that configuration.  This change is 

     completely backwards compatible and passes the perl-framework.  Minor

     mmn bump because I add a field to server_rec.  [Sander Temme]     

  *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.

     [Garrett Rooney, Jim Jagielski, Paul Querna]

Changes with Apache 2.2.3

     successfully revalidated cached objects. PR 39647. [Ruediger Pluem]

  *) mod_speling: Add directive to deal with case corrections only

     and ignore other misspellings [Olivier Thereaux  <ot w3.org>]

  *) mod_dbd: Fix dependence on virtualhost configuration in

     defining prepared statements (possible segfault at startup

     in user modules such as mod_authn_dbd).  [Nick Kew]

  *) Add optional 'scheme://' prefix to ServerName directive,

     allowing correct determination of the canonical server URL

     for use behind a proxy or offload device handling SSL; fixing

     redirect generation in those cases. PR 33398. [Sander Temme]

  *) Added server_scheme field to server_rec for above. Minor MMN bump.

     [Sander Temme]

  *) Worker MPM: On graceless shutdown or restart, send signals to

     Keep-Alive connection.  PR 38737.  [Chris Darroch]

     take a long time.  PR 39275.
