<p>Esta directiva hace posible mejoras específicas a nivel de sistema operativo
y a través del tipo de Protocolo para un socket que escucha.
La premisa básica es que el kernel no envíe un socket al servidor
hasta que o bien los datos se hayan recibido o bien se haya almacenado
en el buffer una Respuesta HTTP completa.
Actualmente sólo están soportados
<a href="http://www.freebsd.org/cgi/man.cgi?query=accept_filter&sektion=9">
Accept Filters</a> sobre FreeBSD, <code>TCP_DEFER_ACCEPT</code> sobre Linux,
y AcceptEx() sobre Windows.</p>
<p>El uso de <code>none</code> para un argumento desactiva cualquier filtro
aceptado para ese protocolo. Esto es útil para protocolos que requieren que un
servidor envíe datos primeros, tales como <code>ftp:</code> o <code>nntp</code>:</p>
<div class="example"><p><code>AcceptFilter nntp none</code></p></div>
<p>Los nombres de protocolo por defecto son <code>https</code> para el puerto 443
y <code>http</code> para todos los demás puertos. Para especificar que se está
utilizando otro protocolo con un puerto escuchando, añade el argumento <var>protocol</var>
a la directiva <code class="directive"><a href="../mod/mpm_common.html#listen">Listen</a></code>.</p>
<p>Sobre FreeBDS los valores por defecto:</p>
<div class="example"><p><code>
AcceptFilter http httpready <br />
AcceptFilter https dataready
</code></p></div>
<p>El filtro <code>httpready</code> almacena en el buffer peticiones HTTP completas
a nivel de kernel. Una vez que la petición es recibida, el kernel la envía al servidor.
Consulta la página man de
<a href="http://www.freebsd.org/cgi/man.cgi?query=accf_http&sektion=9">
accf_http(9)</a> para más detalles. Puesto que las peticiones HTTPS
están encriptadas, sólo se utiliza el filtro
<a href="http://www.freebsd.org/cgi/man.cgi?query=accf_data&sektion=9">accf_data(9)</a>.</p>
<p>Sobre Linux los valores por defecto son:</p>
<div class="example"><p><code>
AcceptFilter http data <br />
AcceptFilter https data
</code></p></div>
<p>En Linux, <code>TCP_DEFER_ACCEPT</code> no soporta el buffering en peticiones http.
Cualquier valor además de <code>none</code> habilitará
<code>TCP_DEFER_ACCEPT</code> en ese socket. Para más detalles
ver la página man de Linux
<a href="http://homepages.cwi.nl/~aeb/linux/man2html/man7/tcp.7.html">
tcp(7)</a>.</p>
<p>Sobre Windows los valores por defecto son:</p>
<div class="example"><p><code>
AcceptFilter http data <br />
AcceptFilter https data
</code></p></div>
<p>Sobre Windows mpm_winnt interpreta el argumento AcceptFilter para conmutar la API
AcceptEx(), y no soporta el buffering sobre el protocolo http. Hay dos valores
que utilizan la API Windows AcceptEx() y que recuperan sockets de red
entre conexciones. <code>data</code> espera hasta que los datos han sido
transmitidos como se comentaba anteriormente, y el buffer inicial de datos y las
direcciones de red son recuperadas a partir de una única llamada AcceptEx().
<code>connect</code> utiliza la API AcceptEx() API, y recupera también
las direcciones de red, pero a diferencia de <code>none</code>
la opción <code>connect</code> no espera a la transmisión inicial de los datos.</p>
<p>Sobre Windows, <code>none</code> prefiere accept() antes que AcceptEx()
y no recuperará sockets entre las conexiones. Lo que es útil para los adaptadores de
red con un soporte precario de drivers, así como para algunos proveedores de red
tales como drivers vpn, o filtros de spam, de virus o de spyware.</p>

<p>Esta directiva controla si las peticiones que contienen información sobre la ruta
que sigue un fichero que existe (o un fichero que no existe pero en un directorio que
sí existe) serán aceptadas o denegadas. La información de ruta puede estar disponible
para los scripts en la variable de entorno <code>PATH_INFO</code>.</p>
<p>Por ejemplo, asumamos que la ubicación <code>/test/</code> apunta a
un directorio que contiene únicamente el fichero
<code>here.html</code>. Entonces, las peticiones tanto para
<code>/test/here.html/more</code> como para
<code>/test/nothere.html/more</code> recogen
<code>/more</code> como <code>PATH_INFO</code>.</p>
<p>Los tres posibles argumentos para la directiva
<code class="directive">AcceptPathInfo</code> son los siguientes:</p>
<dl>
<dt><code>Off</code></dt><dd>Una petición sólo será aceptada si
se corresponde con una ruta literal que existe. Por lo tanto, una petición
con una información de ruta después del nombre de fichero tal como
<code>/test/here.html/more</code> en el ejemplo anterior devolverá
un error 404 NOT FOUND.</dd>
<dt><code>On</code></dt><dd>Una petición será aceptada si una
ruta principal de acceso se corresponde con un fichero que existe. El ejemplo
anterior <code>/test/here.html/more</code> será aceptado si
<code>/test/here.html</code> corresponde a un fichero válido.</dd>
<dt><code>Default</code></dt><dd>La gestión de las peticiones
con información de ruta está determinada por el <a href="../handler.html">controlador</a> responsable de la petición.
El controlador principal para para ficheros normales rechaza por defecto
peticiones <code>PATH_INFO</code>. Los controladores que sirven scripts, tales como <a href="mod_cgi.html">cgi-script</a> e <a href="mod_isapi.html">isapi-handler</a>, normalmente aceptan
<code>PATH_INFO</code> por defecto.</dd>
</dl>
<p>El objetivo principal de la directiva <code>AcceptPathInfo</code>
es permitirte sobreescribir la opción del controlador
de aceptar or rechazar <code>PATH_INFO</code>. Este tipo de sobreescritura se necesita,
por ejemplo, cuando utilizas un <a href="../filter.html">filtro</a>, tal como
<a href="mod_include.html">INCLUDES</a>, para generar contenido
basado en <code>PATH_INFO</code>. El controlador principal normalmente rechazaría
la petición, de modo que puedes utilizar la siguiente configuración para habilitarla
como script:</p>
<div class="example"><p><code>
<Files "mypaths.shtml"><br />
<span class="indent">
Options +Includes<br />
SetOutputFilter INCLUDES<br />
AcceptPathInfo On<br />
</span>
</Files>
</code></p></div>

<p>This directive specifies a default value for the media type
charset parameter (the name of a character encoding) to be added
to a response if and only if the response's content-type is either
<code>text/plain</code> or <code>text/html</code>. This should override
any charset specified in the body of the response via a <code>META</code>
element, though the exact behavior is often dependent on the user's client
configuration. A setting of <code>AddDefaultCharset Off</code>
disables this functionality. <code>AddDefaultCharset On</code> enables
a default charset of <code>iso-8859-1</code>. Any other value is assumed
to be the <var>charset</var> to be used, which should be one of the
<a href="http://www.iana.org/assignments/character-sets">IANA registered
charset values</a> for use in Internet media types (MIME types).
For example:</p>
<div class="example"><p><code>
AddDefaultCharset utf-8
</code></p></div>
<p><code class="directive">AddDefaultCharset</code> should only be used when all
of the text resources to which it applies are known to be in that
character encoding and it is too inconvenient to label their charset
individually. One such example is to add the charset parameter
to resources containing generated content, such as legacy CGI
scripts, that might be vulnerable to cross-site scripting attacks
due to user-provided data being included in the output. Note, however,
that a better solution is to just fix (or delete) those scripts, since
setting a default charset does not protect users that have enabled
the "auto-detect character encoding" feature on their browser.</p>

<p>This directive enables the generation of
<code>Content-MD5</code> headers as defined in RFC1864
respectively RFC2616.</p>
<p>MD5 is an algorithm for computing a "message digest"
(sometimes called "fingerprint") of arbitrary-length data, with
a high degree of confidence that any alterations in the data
will be reflected in alterations in the message digest.</p>
<p>The <code>Content-MD5</code> header provides an end-to-end
message integrity check (MIC) of the entity-body. A proxy or
client may check this header for detecting accidental
modification of the entity-body in transit. Example header:</p>
<div class="example"><p><code>
Content-MD5: AuLb7Dp1rqtRtxz2m9kRpA==
</code></p></div>
<p>Note that this can cause performance problems on your server
since the message digest is computed on every request (the
values are not cached).</p>
<p><code>Content-MD5</code> is only sent for documents served
by the <code class="module"><a href="../mod/core.html">core</a></code>, and not by any module. For example,
SSI documents, output from CGI scripts, and byte range responses
do not have this header.</p>

<p><code class="directive"><Directory></code> and
<code></Directory></code> are used to enclose a group of
directives that will apply only to the named directory,
sub-directories of that directory, and the files within the respective
directories. Any directive that is allowed
in a directory context may be used. <var>Directory-path</var> is
either the full path to a directory, or a wild-card string using
Unix shell-style matching. In a wild-card string, <code>?</code> matches
any single character, and <code>*</code> matches any sequences of
characters. You may also use <code>[]</code> character ranges. None
of the wildcards match a `/' character, so <code><Directory
/*/public_html></code> will not match
<code>/home/user/public_html</code>, but <code><Directory
/home/*/public_html></code> will match. Example:</p>
<div class="example"><p><code>
<Directory /usr/local/httpd/htdocs><br />
<span class="indent">
Options Indexes FollowSymLinks<br />
</span>
</Directory>
</code></p></div>
<div class="note">
<p>Be careful with the <var>directory-path</var> arguments:
They have to literally match the filesystem path which Apache httpd uses
to access the files. Directives applied to a particular
<code><Directory></code> will not apply to files accessed from
that same directory via a different path, such as via different symbolic
links.</p>
</div>
<p><a class="glossarylink" href="../glossary.html#regex" title="ver glosario">Regular
expressions</a> can also be used, with the addition of the
<code>~</code> character. For example:</p>
<div class="example"><p><code>
<Directory ~ "^/www/.*/[0-9]{3}">
</code></p></div>
<p>would match directories in <code>/www/</code> that consisted of
three numbers.</p>
<p>If multiple (non-regular expression) <code class="directive"><Directory></code> sections
match the directory (or one of its parents) containing a document,
then the directives are applied in the order of shortest match
first, interspersed with the directives from the <a href="#accessfilename">.htaccess</a> files. For example,
with</p>
<div class="example"><p><code>
<Directory /><br />
<span class="indent">
AllowOverride None<br />
</span>
</Directory><br />
<br />
<Directory /home/><br />
<span class="indent">
AllowOverride FileInfo<br />
</span>
</Directory>
</code></p></div>
<p>for access to the document <code>/home/web/dir/doc.html</code>
the steps are:</p>
<ul>
<li>Apply directive <code>AllowOverride None</code>
(disabling <code>.htaccess</code> files).</li>
<li>Apply directive <code>AllowOverride FileInfo</code> (for
directory <code>/home</code>).</li>
<li>Apply any <code>FileInfo</code> directives in
<code>/home/.htaccess</code>, <code>/home/web/.htaccess</code> and
<code>/home/web/dir/.htaccess</code> in that order.</li>
</ul>
<p>Regular expressions are not considered until after all of the
normal sections have been applied. Then all of the regular
expressions are tested in the order they appeared in the
configuration file. For example, with</p>
<div class="example"><p><code>
<Directory ~ abc$><br />
<span class="indent">
# ... directives here ...<br />
</span>
</Directory>
</code></p></div>
<p>the regular expression section won't be considered until after
all normal <code class="directive"><Directory></code>s and
<code>.htaccess</code> files have been applied. Then the regular
expression will match on <code>/home/abc/public_html/abc</code> and
the corresponding <code class="directive"><Directory></code> will
be applied.</p>
<p><strong>Note that the default access for
<code><Directory /></code> is <code>Allow from All</code>.
This means that Apache httpd will serve any file mapped from an URL. It is
recommended that you change this with a block such
as</strong></p>
<div class="example"><p><code>
<Directory /><br />
<span class="indent">
Order Deny,Allow<br />
Deny from All<br />
</span>
</Directory>
</code></p></div>
<p><strong>and then override this for directories you
<em>want</em> accessible. See the <a href="../misc/security_tips.html">Security Tips</a> page for more
details.</strong></p>
<p>The directory sections occur in the <code>httpd.conf</code> file.
<code class="directive"><Directory></code> directives
cannot nest, and cannot appear in a <code class="directive"><a href="#limit"><Limit></a></code> or <code class="directive"><a href="#limitexcept"><LimitExcept></a></code> section.</p>

<p><code class="directive"><DirectoryMatch></code> and
<code></DirectoryMatch></code> are used to enclose a group
of directives which will apply only to the named directory (and the files within),
the same as <code class="directive"><a href="#directory"><Directory></a></code>.
However, it takes as an argument a
<a class="glossarylink" href="../glossary.html#regex" title="ver glosario">regular expression</a>. For example:</p>
<div class="example"><p><code>
<DirectoryMatch "^/www/(.+/)?[0-9]{3}">
</code></p></div>
<p>would match directories in <code>/www/</code> that consisted of three
numbers.</p>
<div class="note"><h3>Compatability</h3>
Prior to 2.3.9, this directive implicitly applied to sub-directories
(like <code class="directive"><a href="#directory"><Directory></a></code>) and
could not match the end of line symbol ($). In 2.3.9 and later,
only directories that match the expression are affected by the enclosed
directives.
</div>
<div class="note"><h3>Trailing Slash</h3>
This directive applies to requests for directories that may or may
not end in a trailing slash, so expressions that are anchored to the
end of line ($) must be written with care.

<p>This directive sets the directory from which <code class="program"><a href="../programs/httpd.html">httpd</a></code>
will serve files. Unless matched by a directive like <code class="directive"><a href="../mod/mod_alias.html#alias">Alias</a></code>, the server appends the
path from the requested URL to the document root to make the
path to the document. Example:</p>
<div class="example"><p><code>
DocumentRoot /usr/web
</code></p></div>
<p>then an access to
<code>http://www.my.host.com/index.html</code> refers to
<code>/usr/web/index.html</code>. If the <var>directory-path</var> is
not absolute then it is assumed to be relative to the <code class="directive"><a href="#serverroot">ServerRoot</a></code>.</p>
<p>The <code class="directive">DocumentRoot</code> should be specified without
a trailing slash.</p>
