+ <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 direccciones 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>. This override is required,
+ for example, when you use a <a href="../filter.html">filter</a>, such
+ as <a href="mod_include.html">INCLUDES</a>, to generate content
+ based on <code>PATH_INFO</code>. The core handler would usually reject
+ the request, so you can use the following configuration to enable
+ such a script:</p>
+
+ <div class="example"><p><code>
+ <Files "mypaths.shtml"><br />
+ <span class="indent">

+ <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>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,

+ of the wildcards match a `/' character, so <code><Directory

+
+ <ul>
+ <li>Apply directive <code>AllowOverride None</code>
+ (disabling <code>.htaccess</code> files).</li>

+ </ul>
+
+ <p>Regular expressions are not considered until after all of the

+
+ <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

+ <p>In the event of a problem or error, Apache httpd can be configured
+ to do one of four things,</p>
+
+ <ol>
+ <li>output a simple hardcoded error message</li>
+
+ <li>output a customized message</li>
+
+ <li>redirect to a local <var>URL-path</var> to handle the
+ problem/error</li>
+
+ <li>redirect to an external <var>URL</var> to handle the
+ problem/error</li>
+ </ol>
+
+ <p>The first option is the default, while options 2-4 are
+ configured using the <code class="directive">ErrorDocument</code>
+ directive, which is followed by the HTTP response code and a URL
+ or a message. Apache httpd will sometimes offer additional information
+ regarding the problem/error.</p>
+
+ <p>URLs can begin with a slash (/) for local web-paths (relative
+ to the <code class="directive"><a href="#documentroot">DocumentRoot</a></code>), or be a
+ full URL which the client can resolve. Alternatively, a message
+ can be provided to be displayed by the browser. Examples:</p>
+
+ <div class="example"><p><code>
+ ErrorDocument 500 http://foo.example.com/cgi-bin/tester<br />
+ ErrorDocument 404 /cgi-bin/bad_urls.pl<br />
+ ErrorDocument 401 /subscription_info.html<br />
+ ErrorDocument 403 "Sorry can't allow you access today"
+ </code></p></div>
+
+ <p>Additionally, the special value <code>default</code> can be used
+ to specify Apache httpd's simple hardcoded message. While not required
+ under normal circumstances, <code>default</code> will restore
+ Apache httpd's simple hardcoded message for configurations that would
+ otherwise inherit an existing <code class="directive">ErrorDocument</code>.</p>
+
+ <div class="example"><p><code>
+ ErrorDocument 404 /cgi-bin/bad_urls.pl<br /><br />
+ <Directory /web/docs><br />
+ <span class="indent">
+ ErrorDocument 404 default<br />
+ </span>
+ </Directory>
+ </code></p></div>
+
+ <p>Note that when you specify an <code class="directive">ErrorDocument</code>
+ that points to a remote URL (ie. anything with a method such as
+ <code>http</code> in front of it), Apache HTTP Server will send a redirect to the
+ client to tell it where to find the document, even if the
+ document ends up being on the same server. This has several
+ implications, the most important being that the client will not
+ receive the original error status code, but instead will
+ receive a redirect status code. This in turn can confuse web
+ robots and other clients which try to determine if a URL is
+ valid using the status code. In addition, if you use a remote
+ URL in an <code>ErrorDocument 401</code>, the client will not
+ know to prompt the user for a password since it will not
+ receive the 401 status code. Therefore, <strong>if you use an
+ <code>ErrorDocument 401</code> directive then it must refer to a local
+ document.</strong></p>
+
+ <p>Microsoft Internet Explorer (MSIE) will by default ignore
+ server-generated error messages when they are "too small" and substitute
+ its own "friendly" error messages. The size threshold varies depending on
+ the type of error, but in general, if you make your error document
+ greater than 512 bytes, then MSIE will show the server-generated
+ error rather than masking it. More information is available in
+ Microsoft Knowledge Base article <a href="http://support.microsoft.com/default.aspx?scid=kb;en-us;Q294807">Q294807</a>.</p>
+
+ <p>Although most error messages can be overriden, there are certain
+ circumstances where the internal messages are used regardless of the
+ setting of <code class="directive"><a href="#errordocument">ErrorDocument</a></code>. In
+ particular, if a malformed request is detected, normal request processing
+ will be immediately halted and the internal error message returned.
+ This is necessary to guard against security problems caused by
+ bad requests.</p>
+
+ <p>If you are using mod_proxy, you may wish to enable
+ <code class="directive"><a href="../mod/mod_proxy.html#proxyerroroverride">ProxyErrorOverride</a></code> so that you can provide
+ custom error messages on behalf of your Origin servers. If you don't enable ProxyErrorOverride,
+ Apache httpd will not generate custom error documents for proxied content.</p>

+
+ <p>Specifying <code>connection</code> or <code>request</code> as first
+ paramter allows to specify additional formats, causing additional
+ information to be logged when the first message is logged for a specific
+ connection or request, respectivly. This additional information is only
+ logged once per connection/request. If a connection or request is processed
+ without causing any log message, the additional information is not logged
+ either.</p>
+
+ <p>It can happen that some format string items do not produce output. For
+ example, the Referer header is only present if the log message is
+ associated to a request and the log message happens at a time when the
+ Referer header has already been read from the client. If no output is
+ produced, the default behaviour is to delete everything from the preceeding
+ space character to the next space character. This means the log line is
+ implicitly divided into fields on non-whitespace to whitespace transitions.
+ If a format string item does not produce output, the whole field is
+ ommitted. For example, if the remote address <code>%a</code> in the log
+ format <code>[%t] [%l] [%a] %M </code> is not available, the surrounding
+ brackets are not logged either. Space characters can be escaped with a
+ backslash to prevent them from delimiting a field. The combination '% '
+ (percent space) is a zero-witdh field delimiter that does not produce any
+ output.</p>
+
+ <p>The above behaviour can be changed by adding modifiers to the format
+ string item. A <code>-</code> (minus) modifier causes a minus to be logged if the
+ respective item does not produce any output. In once-per-connection/request
+ formats, it is also possible to use the <code>+</code> (plus) modifier. If an
+ item with the plus modifier does not produce any output, the whole line is
+ ommitted.</p>
+
+ <p>A number as modifier can be used to assign a log severity level to a
+ format item. The item will only be logged if the severity of the log
+ message is not higher than the specified log severity level. The number can
+ range from 1 (alert) over 4 (warn) and 7 (debug) to 15 (trace8).</p>

+ The <code class="directive">FileETag</code> directive configures the file
+ attributes that are used to create the <code>ETag</code> (entity
+ tag) response header field when the document is based on a static file.
+ (The <code>ETag</code> value is used in cache management to save
+ network bandwidth.) The
+ <code class="directive">FileETag</code> directive allows you to choose
+ which of these -- if any -- should be used. The recognized keywords are:
+ </p>
+
+ <dl>
+ <dt><strong>INode</strong></dt>
+ <dd>The file's i-node number will be included in the calculation</dd>
+ <dt><strong>MTime</strong></dt>
+ <dd>The date and time the file was last modified will be included</dd>
+ <dt><strong>Size</strong></dt>
+ <dd>The number of bytes in the file will be included</dd>
+ <dt><strong>All</strong></dt>
+ <dd>All available fields will be used. This is equivalent to:
+ <div class="example"><p><code>FileETag INode MTime Size</code></p></div></dd>
+ <dt><strong>None</strong></dt>
+ <dd>If a document is file-based, no <code>ETag</code> field will be
+ included in the response</dd>
+ </dl>
+
+ <p>The <code>INode</code>, <code>MTime</code>, and <code>Size</code>
+ keywords may be prefixed with either <code>+</code> or <code>-</code>,
+ which allow changes to be made to the default setting inherited
+ from a broader scope. Any keyword appearing without such a prefix
+ immediately and completely cancels the inherited setting.</p>
+
+ <p>If a directory's configuration includes
+ <code>FileETag INode MTime Size</code>, and a
+ subdirectory's includes <code>FileETag -INode</code>,
+ the setting for that subdirectory (which will be inherited by
+ any sub-subdirectories that don't override it) will be equivalent to
+ <code>FileETag MTime Size</code>.</p>
+ <div class="warning"><h3>Warning</h3>
+ Do not change the default for directories or locations that have WebDAV
+ enabled and use <code class="module"><a href="../mod/mod_dav_fs.html">mod_dav_fs</a></code> as a storage provider.
+ <code class="module"><a href="../mod/mod_dav_fs.html">mod_dav_fs</a></code> uses <code>INode MTime Size</code>
+ as a fixed format for <code>ETag</code> comparisons on conditional requests.
+ These conditional requests will break if the <code>ETag</code> format is
+ changed via <code class="directive">FileETag</code>.
+ </div>
+ <div class="note"><h3>Server Side Includes</h3>
+ An ETag is not generated for responses parsed by <code class="module"><a href="../mod/mod_include.html">mod_include</a></code>,
+ since the response entity can change without a change of the INode, MTime, or Size
+ of the static file with embedded SSI directives.

+ <p>The <code class="directive"><Files></code> directive
+ limits the scope of the enclosed directives by filename. It is comparable
+ to the <code class="directive"><a href="#directory"><Directory></a></code>
+ and <code class="directive"><a href="#location"><Location></a></code>
+ directives. It should be matched with a <code></Files></code>
+ directive. The directives given within this section will be applied to
+ any object with a basename (last component of filename) matching the
+ specified filename. <code class="directive"><Files></code>
+ sections are processed in the order they appear in the
+ configuration file, after the <code class="directive"><a href="#directory"><Directory></a></code> sections and
+ <code>.htaccess</code> files are read, but before <code class="directive"><a href="#location"><Location></a></code> sections. Note
+ that <code class="directive"><Files></code> can be nested
+ inside <code class="directive"><a href="#directory"><Directory></a></code> sections to restrict the
+ portion of the filesystem they apply to.</p>
+
+ <p>The <var>filename</var> argument should include a filename, or
+ a wild-card string, where <code>?</code> matches any single character,
+ and <code>*</code> matches any sequences of characters.
+ <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>
+ <Files ~ "\.(gif|jpe?g|png)$">
+ </code></p></div>
+
+ <p>would match most common Internet graphics formats. <code class="directive"><a href="#filesmatch"><FilesMatch></a></code> is preferred,
+ however.</p>
+
+ <p>Note that unlike <code class="directive"><a href="#directory"><Directory></a></code> and <code class="directive"><a href="#location"><Location></a></code> sections, <code class="directive"><Files></code> sections can be used inside
+ <code>.htaccess</code> files. This allows users to control access to
+ their own files, at a file-by-file level.</p>
