+
+<summary>
+    <p>The directives provided by <module>mod_access_compat</module> are
+    used in <directive module="core" type="section">Directory</directive>,
+    <directive module="core" type="section">Files</directive>, and
+    <directive module="core" type="section">Location</directive> sections
+    as well as <code><a href="core.html#accessfilename">.htaccess</a>
+    </code> files to control access to particular parts of the server.
+    Access can be controlled based on the client hostname, IP address, or
+    other characteristics of the client request, as captured in <a
+    href="../env.html">environment variables</a>. The <directive
+    module="mod_access_compat">Allow</directive> and <directive
+    module="mod_access_compat">Deny</directive> directives are used to
+    specify which clients are or are not allowed access to the server,
+    while the <directive module="mod_access_compat">Order</directive>
+    directive sets the default access state, and configures how the
+    <directive module="mod_access_compat">Allow</directive> and <directive
+    module="mod_access_compat">Deny</directive> directives interact with each
+    other.</p>
+
+    <p>Both host-based access restrictions and password-based
+    authentication may be implemented simultaneously. In that case,
+    the <directive module="core">Satisfy</directive> directive is used
+    to determine how the two sets of restrictions interact.</p>
+
+    <note type="warning"><title>Note</title>

+      <module>mod_authz_default</module> must also be loaded to provide for
+      default authorization handling.</p>
+    </note>
+
+    <p>In general, access restriction directives apply to all
+    access methods (<code>GET</code>, <code>PUT</code>,
+    <code>POST</code>, etc). This is the desired behavior in most
+    cases. However, it is possible to restrict some methods, while
+    leaving other methods unrestricted, by enclosing the directives
+    in a <directive module="core" type="section">Limit</directive> section.</p>

+
+<usage>
+    <p>The <directive>Allow</directive> directive affects which hosts can
+    access an area of the server. Access can be controlled by
+    hostname, IP Address, IP Address range, or by other
+    characteristics of the client request captured in environment
+    variables.</p>
+
+    <p>The first argument to this directive is always
+    <code>from</code>. The subsequent arguments can take three
+    different forms. If <code>Allow from all</code> is specified, then
+    all hosts are allowed access, subject to the configuration of the
+    <directive module="mod_access_compat">Deny</directive> and <directive
+    module="mod_access_compat">Order</directive> directives as discussed
+    below. To allow only particular hosts or groups of hosts to access
+    the server, the <em>host</em> can be specified in any of the
+    following formats:</p>
+
+    <dl>
+      <dt>A (partial) domain-name</dt>
+
+      <dd>
+      <example><title>Example:</title>
+        Allow from apache.org<br />
+        Allow from .net example.edu
+      </example>
+      <p>Hosts whose names match, or end in, this string are allowed
+      access. Only complete components are matched, so the above
+      example will match <code>foo.apache.org</code> but it will not
+      match <code>fooapache.org</code>. This configuration will cause
+      Apache to perform a double reverse DNS lookup on the client IP
+      address, regardless of the setting of the <directive
+      module="core">HostnameLookups</directive> directive.  It will do
+      a reverse DNS lookup on the IP address to find the associated
+      hostname, and then do a forward lookup on the hostname to assure
+      that it matches the original IP address.  Only if the forward
+      and reverse DNS are consistent and the hostname matches will
+      access be allowed.</p></dd>
+
+      <dt>A full IP address</dt>
+
+      <dd>
+      <example><title>Example:</title>
+        Allow from 10.1.2.3<br />
+        Allow from 192.168.1.104 192.168.1.205
+      </example>
+      <p>An IP address of a host allowed access</p></dd>
+
+      <dt>A partial IP address</dt>
+
+      <dd>
+      <example><title>Example:</title>
+        Allow from 10.1<br />
+        Allow from 10 172.20 192.168.2
+      </example>
+      <p>The first 1 to 3 bytes of an IP address, for subnet
+      restriction.</p></dd>
+
+      <dt>A network/netmask pair</dt>
+
+      <dd>
+      <example><title>Example:</title>
+        Allow from 10.1.0.0/255.255.0.0
+      </example>
+      <p>A network a.b.c.d, and a netmask w.x.y.z. For more
+      fine-grained subnet restriction.</p></dd>
+
+      <dt>A network/nnn CIDR specification</dt>
+
+      <dd>
+      <example><title>Example:</title>
+        Allow from 10.1.0.0/16
+      </example>
+      <p>Similar to the previous case, except the netmask consists of
+      nnn high-order 1 bits.</p></dd>
+    </dl>
+
+    <p>Note that the last three examples above match exactly the
+    same set of hosts.</p>
+
+    <p>IPv6 addresses and IPv6 subnets can be specified as shown
+    below:</p>
+
+    <example>
+       Allow from 2001:db8::a00:20ff:fea7:ccea<br />
+       Allow from 2001:db8::a00:20ff:fea7:ccea/10
+    </example>
+
+    <p>The third format of the arguments to the
+    <directive>Allow</directive> directive allows access to the server
+    to be controlled based on the existence of an <a
+    href="../env.html">environment variable</a>. When <code>Allow from
+    env=<var>env-variable</var></code> is specified, then the request is
+    allowed access if the environment variable <var>env-variable</var>
+    exists. The server provides the ability to set environment
+    variables in a flexible way based on characteristics of the client
+    request using the directives provided by
+    <module>mod_setenvif</module>. Therefore, this directive can be
+    used to allow access based on such factors as the clients
+    <code>User-Agent</code> (browser type), <code>Referer</code>,
or
+    other HTTP request header fields.</p>
+
+    <example><title>Example:</title>
+      SetEnvIf User-Agent ^KnockKnock/2\.0 let_me_in<br />
+      &lt;Directory /docroot&gt;<br />
+      <indent>
+        Order Deny,Allow<br />
+        Deny from all<br />
+        Allow from env=let_me_in<br />
+      </indent>
+      &lt;/Directory&gt;
+    </example>
+
+    <p>In this case, browsers with a user-agent string beginning
+    with <code>KnockKnock/2.0</code> will be allowed access, and all
+    others will be denied.</p>

+      <directive module="mod_access_compat">Deny</directive> directive or does
+      match an <directive module="mod_access_compat">Allow</directive>
+      directive will be allowed access to the server.</dd>
+
+      <dt><code>Allow,Deny</code></dt>
+
+      <dd>The <directive module="mod_access_compat">Allow</directive>
+      directives are evaluated before the <directive
+      module="mod_access_compat">Deny</directive> directives. Access is denied
+      by default. Any client which does not match an <directive
+      module="mod_access_compat">Allow</directive> directive or does match a
+      <directive module="mod_access_compat">Deny</directive> directive will be
+      denied access to the server.</dd>
+
+      <dt><code>Mutual-failure</code></dt>
+
+      <dd>Only those hosts which appear on the <directive
+      module="mod_access_compat">Allow</directive> list and do not appear on
+      the <directive module="mod_access_compat">Deny</directive> list are
+      granted access. This ordering has the same effect as <code>Order
+      Allow,Deny</code> and is deprecated in favor of that
+      configuration.</dd>
+    </dl>
+
+    <p>Keywords may only be separated by a comma; <em>no whitespace</em>
is
+    allowed between them. Note that in all cases every <directive
+    module="mod_access_compat">Allow</directive> and <directive
+    module="mod_access_compat">Deny</directive> statement is evaluated.</p>
+
+    <p>In the following example, all hosts in the apache.org domain
+    are allowed access; all other hosts are denied access.</p>
+
+    <example>
+      Order Deny,Allow<br />
+      Deny from all<br />
+      Allow from apache.org
+    </example>
+
+    <p>In the next example, all hosts in the apache.org domain are
+    allowed access, except for the hosts which are in the
+    foo.apache.org subdomain, who are denied access. All hosts not
+    in the apache.org domain are denied access because the default
+    state is to deny access to the server.</p>
+
+    <example>
+      Order Allow,Deny<br />
+      Allow from apache.org<br />
+      Deny from foo.apache.org
+    </example>
+
+    <p>On the other hand, if the <directive>Order</directive> in the last
+    example is changed to <code>Deny,Allow</code>, all hosts will
+    be allowed access. This happens because, regardless of the
+    actual ordering of the directives in the configuration file,
+    the <code>Allow from apache.org</code> will be evaluated last
+    and will override the <code>Deny from foo.apache.org</code>.
+    All hosts not in the <code>apache.org</code> domain will also
+    be allowed access because the default state will change to
+    <em>allow</em>.</p>
+
+    <p>The presence of an <directive>Order</directive> directive can affect
+    access to a part of the server even in the absence of accompanying
+    <directive module="mod_access_compat">Allow</directive> and <directive
+    module="mod_access_compat">Deny</directive> directives because of its effect
+    on the default access state. For example,</p>
+
+    <example>
+      &lt;Directory /www&gt;<br />
+      <indent>
+        Order Allow,Deny<br />
+      </indent>
+      &lt;/Directory&gt;
+    </example>
+
+    <p>will deny all access to the <code>/www</code> directory
+    because the default access state will be set to
+    <em>deny</em>.</p>
+
+    <p>The <directive>Order</directive> directive controls the order of
access
+    directive processing only within each phase of the server's
+    configuration processing. This implies, for example, that an
+    <directive module="mod_access_compat">Allow</directive> or <directive
+    module="mod_access_compat">Deny</directive> directive occurring in a
+    <directive module="core" type="section">Location</directive> section will
+    always be evaluated after an <directive
+    module="mod_access_compat">Allow</directive> or <directive
+    module="mod_access_compat">Deny</directive> directive occurring in a
+    <directive module="core" type="section">Directory</directive> section or
+    <code>.htaccess</code> file, regardless of the setting of the
+    <directive>Order</directive> directive. For details on the merging
+    of configuration sections, see the documentation on <a
+    href="../sections.html">How Directory, Location and Files sections

+<usage>
+    <p>Access policy if both <directive
+    module="mod_authz_host">Allow</directive> and <directive
+    module="mod_authz_core">Require</directive> used. The parameter can be
+    either <code>All</code> or <code>Any</code>. This directive is
only
+    useful if access to a particular area is being restricted by both
+    username/password <em>and</em> client host address. In this case
+    the default behavior (<code>All</code>) is to require that the client
+    passes the address access restriction <em>and</em> enters a valid
+    username and password. With the <code>Any</code> option the client will be
+    granted access if they either pass the host restriction or enter a
+    valid username and password. This can be used to password restrict
+    an area, but to let clients from particular addresses in without
+    prompting for a password.</p>
+
+    <p>For example, if you wanted to let people on your network have
+    unrestricted access to a portion of your website, but require that
+    people outside of your network provide a password, you could use a
+    configuration similar to the following:</p>
+
+    <example>
+      Require valid-user<br />
+      Allow from 192.168.1<br />
+      Satisfy Any
+    </example>
+
+    <p>Since version 2.0.51 <directive>Satisfy</directive> directives can
+    be restricted to particular methods by <directive module="core"
+    type="section">Limit</directive> and <directive module="core" type="section"
+    >LimitExcept</directive> sections.</p>
