+<h3>Summary</h3>
+
+    <p>This module is used to treat the useragent which initiated the
+    request as the originating useragent as identified by httpd for the
+    purposes of authorization and logging, even where that useragent is
+    behind a load balancer, front end server, or proxy server.</p>
+
+    <p>The module overrides the client IP address for the connection
+    with the useragent IP address reported in the request header configured
+    with the <code class="directive"><a href="#remoteipheader">RemoteIPHeader</a></code> directive.</p>
+
+    <p>Additionally, this module implements the server side of
+    HAProxy's
+    <a href="http://blog.haproxy.com/haproxy/proxy-protocol/">PROXY Protocol</a> when
+    using the <code class="directive"><a href="#remoteipproxyprotocol">RemoteIPProxyProtocol</a></code>
+    directive.</p>
+
+    <p>Once replaced as instructed, this overridden useragent IP address is
+    then used for the <code class="module"><a href="../mod/mod_authz_host.html">mod_authz_host</a></code>
+    <code class="directive"><a href="../mod/mod_authz_core.html#require">Require ip</a></code>
+    feature, is reported by <code class="module"><a href="../mod/mod_status.html">mod_status</a></code>, and is recorded by
+    <code class="module"><a href="../mod/mod_log_config.html">mod_log_config</a></code> <code>%a</code> and <code class="module"><a href="../mod/core.html">core</a></code>
+    <code>%a</code> format strings. The underlying client IP of the connection
+    is available in the <code>%{c}a</code> format string.</p>
+
+    <div class="warning">It is critical to only enable this behavior from
+    intermediate hosts (proxies, etc) which are trusted by this server, since
+    it is trivial for the remote useragent to impersonate another
+    useragent.</div>

+<h2><a name="processing" id="processing">Remote IP Processing</a></h2>
+
+    <p>Apache by default identifies the useragent with the connection's
+    client_ip value, and the connection remote_host and remote_logname are
+    derived from this value. These fields play a role in authentication,
+    authorization and logging and other purposes by other loadable
+    modules.</p>
+
+    <p>mod_remoteip overrides the client IP of the connection with the
+    advertised useragent IP as provided by a proxy or load balancer, for
+    the duration of the request. A load balancer might establish a long
+    lived keepalive connection with the server, and each request will
+    have the correct useragent IP, even though the underlying client IP
+    address of the load balancer remains unchanged.</p>
+
+    <p>When multiple, comma delimited useragent IP addresses are listed in the
+    header value, they are processed in Right-to-Left order.  Processing
+    halts when a given useragent IP address is not trusted to present the
+    preceding IP address.  The header field is updated to this remaining
+    list of unconfirmed IP addresses, or if all IP addresses were trusted,
+    this header is removed from the request altogether.</p>
+
+    <p>In overriding the client IP, the module stores the list of intermediate
+    hosts in a remoteip-proxy-ip-list note, which <code class="module"><a href="../mod/mod_log_config.html">mod_log_config</a></code>
+    can record using the <code>%{remoteip-proxy-ip-list}n</code> format token.
+    If the administrator needs to store this as an additional header, this
+    same value can also be recording as a header using the directive
+    <code class="directive"><a href="#remoteipproxiesheader">RemoteIPProxiesHeader</a></code>.</p>
+
+    <div class="note"><h3>IPv4-over-IPv6 Mapped Addresses</h3>
+    As with httpd in general, any IPv4-over-IPv6 mapped addresses are recorded
+    in their IPv4 representation.</div>

+    virtual hosts for the same host and port, and you enable it for any one of
+    them, then it is enabled for all of them (with that host and port). It also
+    means that if you attempt to enable the PROXY protocol in one and disable
+    in the other, that won't work; in such a case, the last one wins and a
