This is the same granularity of control as mod_mime gave to set handlers
(and now AddInputFilter and AddOutputFilter by extension) so this seems
entirely appropriate in the core as well. Options FileInfo is required
to change the processing behavior of files.
*) Modfied mod_mime to prevent mod_negotation from serving a multiview
of a 'handler' or 'filter', so that any filename extension that does
not contribute to the negotiated metadata can't be served without
an explicit request. E.g., if the .Z extension is associated with
an unzip filter, the user request somefile.Z.html, mod_negotiation
won't serve it. It can serve somefile.Z.html when somefile.Z is
requested, since the .Z extension is explictly requested, if the
.html extension is associated with ContentType text/html.
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.
Someone pointed out that we were running the images through the INCLUDE
filter. This fixes it, in a sort of hackish way.
I don't remember who noticed this, sorry :(
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

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!

The consensus now is that mod_include should just butt out of any decisions
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.

Allow mod_ssl to send back an error message if an HTTP request is sent
over an HTTPS connection. This also adds an ap_remove_input_filter
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.

Split proxy: space using <Proxy[Match] > directive blocks from
the <Directory[Match] > and <Files[Match] > blocks. Mod_proxy
now bypasses the directory and files testing phase (and skips
the http TRACE default handler on it's own, as well). Note that
<Location > blocks continue to be processed for proxy: requests.
Remaining questions include canonicalization and case folding
of proxied uri space, prior to the proxy_walk testing and the
second <Location > walk.

Fix a double-free condition when byterange requests are made on brigades
containing any bucket that cannot be copied natively (ie, pipe or socket
buckets).
Before, we were reading that bucket to morph it to a heap bucket and then
taking the str that heap bucket points to and placing it in a second,
completely separate heap bucket. That means we'd have two apr_bucket/
apr_bucket_heap pairs each with a refcount of 1 (rather than two apr_buckets
and a single apr_bucket_heap with a refcount of 2). str would then be
doubly-freed when the second of those two buckets was destroyed.
Commit this code before another patch becomes to difficult to follow.
This patch does one thing, it changes the root path "/" to reflect an
element count of Zero (0). directory_walk will always accept the zero
element (which sorts first, thankfully) on it's first go around.
So, Unix will accept "/" when it's parsing it's first element "/".
Dos/Win32 will accept "/" and "C:/" when they parse their first element,
"C:/". The root sorted first, so it behaves as users expect.
The syntax "//" or "//machine" will be depreciated for now, the user
needs to set up the extact "//machine/share/" that they want served
on Win32.
