that shared mem, LDAP servers, DBs, etc. can also be used for proxy
caching. The caching API is very young, and subject to change as APR changes.

proxy_cache.c from the proxy subdir is no longer used.

Build with --enable-modules=proxy,cache

Lightly tested on Linux, no warranties expressed or implied yet.

Still to do:

strerror(), waitpid(), stat() cleanups
address issues marked by @@@FIXME
add HTTP/1.1

This should be considered a *reference* proxy implementation for 2.0. What
actually ends up shipping with 2.0 is likely going to be rather different as
the redesign evolves. This may end up being the 2.0 backwards compatibility
workalike.

perror() was converted to ap_log_error(), which will interpret the
specified APR error code properly.

The existing ap_log_error() call was changed so that the message is
formatted properly.  Note that this call is made from the mpm after
we detach from the foreground process, so it can only appear in the
log.

around the creation of the httpd.pid file.  Pass explicit permissions to
ap_open(), omitting write-ability except by the owning user.  As always,
we end up with rw-r--r-- for the permissions unless the umask is something
unusual.

Note that the OS/2 and Win32 implementations of ap_open() ignore the
permissions parameter altogether.

1) symptom: on system with bad/no DNS setup, ServerName isn't
   processed so init fails

cause:

  ap_fini_vhost_config() called before ap_process_config_tree(), so
  ServerName was never stored in the config structure

2) symptom: on system with virtual hosts configured, SIGSEGV in
   open_multi_logs()

cause:

   the module configs for the virtual hosts haven't been merged in
   yet, and open_multi_logs() gets NULL for the mod_log_config
   configuration

This stuff needs to be cleaned up further, exploring the use of a
post-config hook for fixup_virtual_hosts(), ap_fini_vhost_config(),
and ap_sort_hooks(), getting a lot of logic out of main(), and
processing the config tree only once.

  A little more cleanup of win_service and windows .html docs.

  Covered the Log On As... option just a little better, with some hints.

  Dire warnings about Win95/98 at the end of the services section.

  Roll back Win95/98 services directives, and just point out differences.

  Get rid of the silly word 'signalling' - which means squat to your
  typical Win32 user!

  Anything else anyone can think of to cover?

src/modules/standard/config.m4:

. don't add "-ldl" to LIBS for FreeBSD either
. back out previous change regarding LTFLAGS; it should be o.k.
  to add it for any platform, because libtool knows what to do with
  it (no, Greg A., I haven't added support for it to OS/390 libtool
  yet :) )

src/lib/apr/configure.in:

  it in the default libraries;
