-<h3>Summary</h3>
-
-    <div class="warning"><h3>Warning</h3>
-      <p>The session modules make use of HTTP cookies, and as such can fall
-      victim to Cross Site Scripting attacks, or expose potentially private
-      information to clients. Please ensure that the relevant risks have
-      been taken into account before enabling the session functionality on
-      your server.</p>
-    </div>
-
-    <p>This submodule of <code class="module"><a href="../mod/mod_session.html">mod_session</a></code> provides support for the
-    storage of user sessions within a SQL database using the
-    <code class="module"><a href="../mod/mod_dbd.html">mod_dbd</a></code> module.</p>
-
-    <p>Sessions can either be <strong>anonymous</strong>, where the session is
-    keyed by a unique UUID string stored on the browser in a cookie, or
-    <strong>per user</strong>, where the session is keyed against the userid of
-    the logged in user.</p>
-
-    <p>SQL based sessions are hidden from the browser, and so offer a measure of
-    privacy without the need for encryption.</p>
-    
-    <p>Different webservers within a server farm may choose to share a database,
-    and so share sessions with one another.</p>
-    
-    <p>For more details on the session interface, see the documentation for
-    the <code class="module"><a href="../mod/mod_session.html">mod_session</a></code> module.</p>

-
-      <p>Before the <code class="module"><a href="../mod/mod_session_dbd.html">mod_session_dbd</a></code> module can be configured to maintain a
-      session, the <code class="module"><a href="../mod/mod_dbd.html">mod_dbd</a></code> module must be configured to make the various database queries
-      available to the server.</p>
-      
-      <p>There are four queries required to keep a session maintained, to select an existing session,
-      to update an existing session, to insert a new session, and to delete an expired or empty
-      session. These queries are configured as per the example below.</p>
-
-      <div class="example"><h3>Sample DBD configuration</h3><p><code>
-        DBDriver pgsql<br />
-        DBDParams "dbname=apachesession user=apache password=xxxxx host=localhost"<br />
-        DBDPrepareSQL "delete from session where key = %s" deletesession<br />
-        DBDPrepareSQL "update session set value = %s, expiry = %lld where key = %s" updatesession<br />
-        DBDPrepareSQL "insert into session (value, expiry, key) values (%s, %lld, %s)" insertsession<br />
-        DBDPrepareSQL "select value from session where key = %s and (expiry = 0 or expiry &gt; %lld)" selectsession<br />
-        DBDPrepareSQL "delete from session where expiry != 0 and expiry &lt; %lld" cleansession<br />

-<h2><a name="anonymous" id="anonymous">Anonymous Sessions</a></h2>
-    
-      <p>Anonymous sessions are keyed against a unique UUID, and stored on the
-      browser within an HTTP cookie. This method is similar to that used by most
-      application servers to store session information.</p>
-    
-      <p>To create a simple anonymous session and store it in a postgres database
-      table called <var>apachesession</var>, and save the session ID in a cookie
-      called <var>session</var>, configure the session as follows:</p>
-      
-      <div class="example"><h3>SQL based anonymous session</h3><p><code>
-        Session On<br />
-        SessionDBDCookieName session path=/<br />
-      </code></p></div>

-      <p>For more examples on how the session can be configured to be read
-      from and written to by a CGI application, see the
-      <code class="module"><a href="../mod/mod_session.html">mod_session</a></code> examples section.</p>
-

-<h2><a name="peruser" id="peruser">Per User Sessions</a></h2>
-    
-      <p>Per user sessions are keyed against the username of a successfully

-      to the session exists outside of the authenticated realm.</p>
-      
-      <p>Per user sessions work within a correctly configured authenticated
-      environment, be that using basic authentication, digest authentication
-      or SSL client certificates. Due to the limitations of who came first,
-      the chicken or the egg, per user sessions cannot be used to store

+<h3>Summary</h3>
+
+    <div class="warning"><h3>Warning</h3>
+      <p>The session modules make use of HTTP cookies, and as such can fall
+      victim to Cross Site Scripting attacks, or expose potentially private
+      information to clients. Please ensure that the relevant risks have
+      been taken into account before enabling the session functionality on
+      your server.</p>
+    </div>
+
+    <p>This submodule of <code class="module"><a href="../mod/mod_session.html">mod_session</a></code> provides support for the
+    storage of user sessions within a SQL database using the
+    <code class="module"><a href="../mod/mod_dbd.html">mod_dbd</a></code> module.</p>
+
+    <p>Sessions can either be <strong>anonymous</strong>, where the session is
+    keyed by a unique UUID string stored on the browser in a cookie, or
+    <strong>per user</strong>, where the session is keyed against the userid of
+    the logged in user.</p>
+
+    <p>SQL based sessions are hidden from the browser, and so offer a measure of
+    privacy without the need for encryption.</p>
+    
+    <p>Different webservers within a server farm may choose to share a database,
+    and so share sessions with one another.</p>
+    
+    <p>For more details on the session interface, see the documentation for
+    the <code class="module"><a href="../mod/mod_session.html">mod_session</a></code> module.</p>

+
+      <p>Before the <code class="module"><a href="../mod/mod_session_dbd.html">mod_session_dbd</a></code> module can be configured to maintain a
+      session, the <code class="module"><a href="../mod/mod_dbd.html">mod_dbd</a></code> module must be configured to make the various database queries
+      available to the server.</p>
+      
+      <p>There are four queries required to keep a session maintained, to select an existing session,
+      to update an existing session, to insert a new session, and to delete an expired or empty
+      session. These queries are configured as per the example below.</p>
+
+      <div class="example"><h3>Sample DBD configuration</h3><p><code>
+        DBDriver pgsql<br />
+        DBDParams "dbname=apachesession user=apache password=xxxxx host=localhost"<br />

+<h2><a name="anonymous" id="anonymous">Anonymous Sessions</a></h2>
+    
+      <p>Anonymous sessions are keyed against a unique UUID, and stored on the
+      browser within an HTTP cookie. This method is similar to that used by most
+      application servers to store session information.</p>
+    
+      <p>To create a simple anonymous session and store it in a postgres database
+      table called <var>apachesession</var>, and save the session ID in a cookie
+      called <var>session</var>, configure the session as follows:</p>
+      
+      <div class="example"><h3>SQL based anonymous session</h3><p><code>

+        SessionDBDCookieName session path=/<br />

+      <p>For more examples on how the session can be configured to be read
+      from and written to by a CGI application, see the
+      <code class="module"><a href="../mod/mod_session.html">mod_session</a></code> examples section.</p>

+      to the session exists outside of the authenticated realm.</p>
+      
+      <p>Per user sessions work within a correctly configured authenticated
+      environment, be that using basic authentication, digest authentication
+      or SSL client certificates. Due to the limitations of who came first,
+      the chicken or the egg, per user sessions cannot be used to store
