rather than on a per-character basis.  A significant amount of time
was spent checking the limit.  A better place to check for the threshold
is when we read the bucket in not as we read each character in the bucket.

If a bucket manages to be 200MB, it is not this code's problem as it
is a mere filter.

I ran this with the mod_include stuff in httpd-test and it looks good
from here.

     Changed syntax of Set{Input|Output}Filter.  The list of filters
     must be semicolon delimited (if more than one filter is given.)
     The Set{Input|Output}Filter directive now overrides a parent
     container's directive (e.g. SetInputFilter in <Directory /web/foo>
     will override any SetInputFilter directive in <Directory /web>.)
     This new syntax is more consistent with Add{Input|Output}Filter
     directives defined in mod_mime.  Also cures a bug in prior releases
     where the Set{Input|Output}Filter directive would corrupt the
     global configuration if the multiple directives were nested.

  Version 1.338 of mod_mime also tightened the mod_negotiation behavior.
  See changes for a complete description.  Because (in the example) the
  .Z extension doesn't affect negotiated behavior, the files index.html
  and index.Z.html couldn't be distinguished, and the user would get an
  error 406 NOT ACCEPTABLE, which is the _wrong_ answer.

  Introduces mod_mime AddInputFilter and AddOutputFilter filter ext syntax.

  Significantly refactored the code to maintain single functions for the
  add_extension_info hash and remove_extension_info table processing.

  The AddInputFilter/AddOutputFilter could have been plural, as they accept
  a semicolon delimited list of filters (e.g. you need to stack two different
  filters based on a single extension.)  I expect that the plural could
  confuse users, though, as they might expect AddInputFilters foo bar var
  to add foo and bar to the extension var, which it definately doesn't do!

about what to do with different request methods.  It's true that mod_include
in 1.3.x did not allow POST, but back then it was a handler.  Now it's a
filter and can be used to filter the output of dynamically generated responses,
even ones resulting from a POST request.  So if mod_include is in the filter
stack, it should just blindly parse the brigade regardless of request method.

This still fixes the security problem, it just fixes it by being more flexible
rather than less so.

function, which should be used to remove the SSL input filter in this
case, as soon as this code is stressed a bit more.

For right now, we are sending the same message that we used to send in
mod_ssl for Apache 1.3.

  Clean up location_walk, so that this step performs a minimum
  amount of redundant effort (it must be run twice, but it will no
  longer reparse all <Location > blocks when the request uri
  hadn't changed.)

  The location walk block is refactored, with some significant changes
  in variable names for legibility.  Cooler still, it uses pool data
  instead of 'notes' for the important cache info :)

  Note the patch builds the <Location > per dir config from _nothing_,
  and then merges it into the per_dir_config.  When the underlying
  per_dir_config changes between passes, the location_walk can simply
  tack back on this preconstruct onto the new per_dir_config.

  Eliminate proxy: (and all other 'special') processing from the
  ap_directory_walk() phase.  Modules that want to use special
  walk logic should refer to the mod_proxy map_to_location example,
  with it's proxy_walk and proxysection implementation.  This makes
  either directory_walk flavor much more legible, since that phase
  only runs against real <Directory > blocks.

  On a technical note, this patch also forces the Directory to be
  canonical (unless it is "/" or a regex.)  It also allows us to
  be more explicit when declaring <Directory > block errors.
