      * Keep the Content-Type for successfully revalidated · 49d8d09a
      Ruediger Pluem authored 
        cached objects, by unsetting possible Content-Type headers in
  r->headers_out and r->err_headers_out as they may be different to what
  we have received from the cache.
  Actually they are not needed as r->content_type set by
  ap_set_content_type a few lines above will be used in the store_headers
  functions of the storage providers as a fallback and the HTTP_HEADER filter
  does overwrite the Content-Type header with r->content_type anyway.

      On graceless shutdown or restart, send AP_SIG_GRACEFUL to all worker · 14774214
      Chris Darroch authored 
      threads so that any that are polling on Keep-Alive connections will
wake up and exit promptly.  Otherwise, on Linux, they wait until
poll()'s timeout interval completes, which is often too long for
the parent process; the parent issues SIGKILL before the child's main
thread manages to re-join all the worker threads.  PR 38737.

On Solaris, by contrast, the close_worker_sockets() function
successfully alerts all worker threads that they should exit quickly.
On Linux, this side-effect of one thread closing another's socket
doesn't occur; see:

http://bugme.osdl.org/show_bug.cgi?id=546

Also, expand on the placeholder in CHANGES regarding previous
cleanups to scoreboard.c and scoreboard.h in r404848 and r404849.

      Make the worker and event MPMs not touch the scoreboard when · 053c9598
      Chris Darroch authored 
      handling a fork() failure.  The previous behaviour appears to have
been inherited from the prefork MPM, where is it appropriate.

The prefork MPM sets thread_limit to 1 and therefore each
child process has a single worker_score structure in the scoreboard's
array, i.e., ap_scoreboard_image->servers[slot][0].  In make_child(),
it sets this structure's status to SERVER_STARTING, and then does
a fork(); if the fork() fails, it resets the status to SERVER_DEAD.

The worker and event MPMs, by constrast, obviously use multiple
worker_score structures per child process.  They may also be
in use by worker threads from a previous generation at any particular
moment.  Therefore make_child() and the parent process in general
doesn't normally update them; make_child() doesn't set them all
to SERVER_STARTING before doing fork(), for example.

So, make_child() shouldn't set them to SERVER_DEAD if fork()
fails (and even if it should, it certainly shouldn't be just
updating the first one).

      * Handle the cases "no proxy request" and "reverse proxy request" in the same · 25ae9a5d
      Ruediger Pluem authored 
        manner, when setting scheme and port_str. This is needed because if a cached
  entry is looked up by mod_cache's quick handler r->proxyreq
  is still unset in the reverse proxy case as it only gets set in the
  translate name hook (either by ProxyPass or mod_rewrite) which is run
  after the quick handler hook. This is different to the forward proxy
  case where it gets set before the quick handler is run (in the
  post_read_request hook).
  If a cache entry is created by the CACHE_SAVE filter we always have
  r->proxyreq set correctly.
  Also set scheme to ap_http_scheme(r) instead of "http" to handle SSL
  correctly.
