The existing faq will be deleted soon.

Discussion to follow on docs list.

  Eliminated ap_os_[systemcase|[case_]canonical]_filename() and
  move ap_os_is_path_absolute() into util.c (now relies on apr.)


git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@90567 13f79535-47bb-0310-9956-ffa450edef68

  Canonicalization will now occur on all sub_req_lookup_file() calls,
  and the ap_server_root_relative() will handle canonicalization as well.


git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@90566 13f79535-47bb-0310-9956-ffa450edef68

  ap_server_root_relative will take care of this canonical_file call.


git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@90565 13f79535-47bb-0310-9956-ffa450edef68

  Performance death notices.  Note that we shouldn't have EVER coded a
  module with a fixed path ... the config phase should take the proxy/
  path and ap_server_root_relative() it at startup.


git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@90564 13f79535-47bb-0310-9956-ffa450edef68

  Optimize out what is a very expensive in-request call to
  ap_server_root_relative (and is becoming more expensive).
  Now the call happens in the config phase where it belongs.
  Note someone can hop in and transpose the stat and open
  with an open and getfileinfo if you are a performance hound.


git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@90563 13f79535-47bb-0310-9956-ffa450edef68

  Clear out this optimization till we are prepared for it (not now.)


git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@90562 13f79535-47bb-0310-9956-ffa450edef68

  Fix most-bogus ap_server_root_relative() cases.  These don't include
  the cases where we are trying to ap_server_root_relative() a pipe cmd!

  This was copied as a test of the ap_r[put|putc|write|printf] family of
  functions.  Since those don't seem to be going anywhere, this test is
  redundant and a maintance headache.


git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@90555 13f79535-47bb-0310-9956-ffa450edef68

Fix for mod_include. Ryan's patch to check error
codes put a return in the wrong place. Also, the
include handler return code wasn't being checked.
I don't like macros with returns, so I converted
SPLIT_AND_PASS_PRETAG_BUCKETS into a function.

It will now reside in the ServerRoot, alongside with .../man/ and .../icons/
and .../htdocs/

Please review the config.layout entries for the vendor specific entries,
I supplied sensible defaults but you may disagree.

implements a quick handler, and three filters. The filters are
CACHE_IN for loading the cache, CACHE_OUT for serving content out of the cache
and CACHE_CONDITIONAL, which handles stale entries in the cache.

mod_cache implements code that makes RFC compliant caching decisions. It
interfaces with the actual storage mechanism via calls to functions defined in
cache_storage.c.  This commit includes a simple in memory (malloc'ed memory)
cache implementation that demonstrates autoloading and serving files
keyed on URL.

This is not even close to production ready. You have been warned :-)

"UnsetEnv does not work from main body of httpd.conf"
PR also complains:
"also does not unsetenv()", but this fix does not address that
(i doubt unsetenv is portable or threadsafe)
