+<h2><a name="ocspstapling" id="ocspstapling">OCSP Stapling</a></h2>
+
+
+<p>The Online Certificate Status Protocol (OCSP) is a mechanism for
+determining whether or not a server certificate has been revoked, and OCSP
+Stapling is a special form of this in which the server, such as httpd and
+mod_ssl, maintains current OCSP responses for its certificates and sends
+them to clients which communicate with the server. Most certificates
+contain the address of an OCSP responder maintained by the issuing
+Certificate Authority, and mod_ssl can communicate with that responder to
+obtain a signed response that can be sent to clients communicating with
+the server.</p>
+
+<p>Because the client can obtain the certificate revocation status from
+the server, without requiring an extra connection from the client to the
+Certificate Authority, OCSP Stapling is the preferred way for the
+revocation status to be obtained. Other benefits of eliminating the
+communication between clients and the Certificate Authority are that the
+client browsing history is not exposed to the Certificate Authority and
+obtaining status is more reliable by not depending on potentially heavily
+loaded Certificate Authority servers.</p>
+
+<p>Because the response obtained by the server can be reused for all clients
+using the same certificate during the time that the response is valid, the
+overhead for the server is minimal.</p>
+
+<p>Once general SSL support has been configured properly, enabling OCSP
+Stapling generally requires only very minor modifications to the httpd
+configuration &#8212; the addition of these two directives:</p>
+
+ <pre class="prettyprint lang-config">SSLUseStapling On
+SSLStaplingCache "shmcb:logs/ssl_stapling(32768)"</pre>
+
+
+<p>These directives are placed at global scope (i.e., not within a virtual
+host definition) wherever other global SSL configuration directives are
+placed, such as in <code>conf/extra/httpd-ssl.conf</code> for normal
+open source builds of httpd, <code>/etc/apache2/mods-enabled/ssl.conf</code>
+for the Ubuntu or Debian-bundled httpd, etc.</p>
+
+<p>The path on the <code class="directive">SSLStaplingCache</code> directive
+(e.g., <code>logs/</code>) should match the one on the
+<code class="directive">SSLSessionCache</code> directive. This path is relative
+to <code class="directive">ServerRoot</code>.</p>
+
+<p>This particular <code class="directive">SSLStaplingCache</code> directive requires
+<code class="module"><a href="../mod/mod_socache_shmcb.html">mod_socache_shmcb</a></code> (from the <code>shmcb</code> prefix on the
+directive's argument). This module is usually enabled already for
+<code class="directive">SSLSessionCache</code> or on behalf of some module other than
+<code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code>. If you enabled an SSL session cache using a
+mechanism other than <code class="module"><a href="../mod/mod_socache_shmcb.html">mod_socache_shmcb</a></code>, use that alternative
+mechanism for <code class="directive">SSLStaplingCache</code> as well. For example:</p>
+
+ <pre class="prettyprint lang-config">SSLSessionCache "dbm:logs/ssl_scache"
+SSLStaplingCache "dbm:logs/ssl_stapling"</pre>
+
+
+<p>You can use the openssl command-line program to verify that an OCSP response
+is sent by your server:</p>
+
+<pre>$ openssl s_client -connect www.example.com:443 -status -servername www.example.com
+...
+OCSP response:
+======================================
+OCSP Response Data:
+ OCSP Response Status: successful (0x0)
+ Response Type: Basic OCSP Response
+...
+ Cert Status: Good
+...</pre>
+
+<p>The following sections highlight the most common situations which require
+further modification to the configuration. Refer also to the
+<code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code> reference manual.</p>
+
+<h3>If more than a few SSL certificates are used for the server</h3>
+
+<p>OCSP responses are stored in the SSL stapling cache. While the responses
+are typically a few hundred to a few thousand bytes in size, mod_ssl
+supports OCSP responses up to around 10K bytes in size. With more than a
+few certificates, the stapling cache size (32768 bytes in the example above)
+may need to be increased. Error message AH01929 will be logged in case of
+an error storing a response.</p>
+
+
+<h3>If the certificate does not point to an OCSP responder, or if a
+different address must be used</h3>
+
+<p>Refer to the
+<code class="directive"><a href="../mod/mod_ssl.html#sslstaplingforceurl">SSLStaplingForceURL</a></code> directive.</p>
+
+<p>You can confirm that a server certificate points to an OCSP responder
+using the openssl command-line program, as follows:</p>
+
+<pre>$ openssl x509 -in ./www.example.com.crt -text | grep 'OCSP.*http'
+OCSP - URI:http://ocsp.example.com</pre>
+
+<p>If the OCSP URI is provided and the web server can communicate to it
+directly without using a proxy, no configuration is required. Note that
+firewall rules that control outbound connections from the web server may
+need to be adjusted.</p>
+
+<p>If no OCSP URI is provided, contact your Certificate Authority to
+determine if one is available; if so, configure it with
+<code class="directive"><a href="../mod/mod_ssl.html#sslstaplingforceurl">SSLStaplingForceURL</a></code> in the virtual
+host that uses the certificate.</p>
+
+
+<h3>If multiple SSL-enabled virtual hosts are configured and OCSP
+Stapling should be disabled for some</h3>
+
+
+<p>Add <code>SSLUseStapling Off</code> to the virtual hosts for which OCSP
+Stapling should be disabled.</p>
+
+
+<h3>If the OCSP responder is slow or unreliable</h3>
+
+<p>Several directives are available to handle timeouts and errors. Refer
+to the documentation for the
+<code class="directive"><a href="../mod/mod_ssl.html#sslstaplingfaketrylater">SSLStaplingFakeTryLater</a></code>,
+<code class="directive"><a href="../mod/mod_ssl.html#sslstaplingrespondertimeout">SSLStaplingResponderTimeout</a></code>, and
+<code class="directive"><a href="../mod/mod_ssl.html#sslstaplingreturnrespondererrors">SSLStaplingReturnResponderErrors</a></code>
+directives.</p>
+
+
+<h3>If mod_ssl logs error AH02217</h3>
+
+<pre>AH02217: ssl_stapling_init_cert: Can't retrieve issuer certificate!</pre>
+<p>In order to support OCSP Stapling when a particular server certificate is
+used, the certificate chain for that certificate must be configured. If it
+was not configured as part of enabling SSL, the AH02217 error will be issued
+when stapling is enabled, and an OCSP response will not be provided for clients
+using the certificate.</p>
+
+<p>Refer to the <code class="directive"><a href="../mod/mod_ssl.html#sslcertificatechainfile">SSLCertificateChainFile</a></code>
+and <code class="directive"><a href="../mod/mod_ssl.html#sslcertificatefile">SSLCertificateFile</a></code> for instructions
+for configuring the certificate chain.</p>

+<h3><a name="allclients" id="allclients">How can I force clients to authenticate using certificates?</a></h3>
+
+
+ <p>When you know all of your users (eg, as is often the case on a corporate
+ Intranet), you can require plain certificate authentication. All you
+ need to do is to create client certificates signed by your own CA
+ certificate (<code>ca.crt</code>) and then verify the clients against this
+ certificate.</p>
+ <pre class="prettyprint lang-config"># require a client certificate which has to be directly
+# signed by our CA certificate in ca.crt
+SSLVerifyClient require
+SSLVerifyDepth 1
+SSLCACertificateFile "conf/ssl.crt/ca.crt"</pre>
+
+
+
+<h3><a name="arbitraryclients" id="arbitraryclients">How can I force clients to authenticate using certificates for a
+ particular URL, but still allow arbitrary clients to access the rest of the server?</a></h3>
+
+
+ <p>To force clients to authenticate using certificates for a particular URL,
+ you can use the per-directory reconfiguration features of
+ <code class="module"><a href="../mod/mod_ssl.html">mod_ssl</a></code>:</p>
+
+ <pre class="prettyprint lang-config">SSLVerifyClient none
+SSLCACertificateFile "conf/ssl.crt/ca.crt"
+
+&lt;Location "/secure/area"&gt;
+SSLVerifyClient require
+SSLVerifyDepth 1
+&lt;/Location&gt;</pre>
+
+
+
+<h3><a name="certauthenticate" id="certauthenticate">How can I allow only clients who have certificates to access a
+ particular URL, but allow all clients to access the rest of the server?</a></h3>
+
+
+ <p>The key to doing this is checking that part of the client certificate
+ matches what you expect. Usually this means checking all or part of the
+ Distinguished Name (DN), to see if it contains some known string.
+ There are two ways to do this, using either <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> or
+ <code class="directive"><a href="../mod/mod_ssl.html#sslrequire">SSLRequire</a></code>.</p>
+
+ <p>The <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> method is generally required when
+ the certificates are completely arbitrary, or when their DNs have
+ no common fields (usually the organisation, etc.). In this case,
+ you should establish a password database containing <em>all</em>
+ clients allowed, as follows:</p>
+
+ <pre class="prettyprint lang-config">SSLVerifyClient none
+SSLCACertificateFile "conf/ssl.crt/ca.crt"
+SSLCACertificatePath "conf/ssl.crt"
+
+&lt;Directory "/usr/local/apache2/htdocs/secure/area"&gt;
+ SSLVerifyClient require
+ SSLVerifyDepth 5
+ SSLOptions +FakeBasicAuth
+ SSLRequireSSL
+ AuthName "Snake Oil Authentication"
+ AuthType Basic
+ AuthBasicProvider file
+ AuthUserFile "/usr/local/apache2/conf/httpd.passwd"
+ Require valid-user
+&lt;/Directory&gt;</pre>
+
+
+ <p>The password used in this example is the DES encrypted string "password".
+ See the <code class="directive"><a href="../mod/mod_ssl.html#ssloptions">SSLOptions</a></code> docs for more
+ information.</p>
+
+ <div class="example"><h3>httpd.passwd</h3><pre>/C=DE/L=Munich/O=Snake Oil, Ltd./OU=Staff/CN=Foo:xxj31ZMTZzkVA
+/C=US/L=S.F./O=Snake Oil, Ltd./OU=CA/CN=Bar:xxj31ZMTZzkVA
+/C=US/L=L.A./O=Snake Oil, Ltd./OU=Dev/CN=Quux:xxj31ZMTZzkVA</pre></div>
+
+ <p>When your clients are all part of a common hierarchy, which is encoded
+ into the DN, you can match them more easily using <code class="directive"><a href="../mod/mod_ssl.html#sslrequire">SSLRequire</a></code>, as follows:</p>
+
+
+ <pre class="prettyprint lang-config">SSLVerifyClient none
+SSLCACertificateFile "conf/ssl.crt/ca.crt"
+SSLCACertificatePath "conf/ssl.crt"
+
+&lt;Directory "/usr/local/apache2/htdocs/secure/area"&gt;
+ SSLVerifyClient require
+ SSLVerifyDepth 5
+ SSLOptions +FakeBasicAuth
+ SSLRequireSSL
+ SSLRequire %{SSL_CLIENT_S_DN_O} eq "Snake Oil, Ltd." \
+ and %{SSL_CLIENT_S_DN_OU} in {"Staff", "CA", "Dev"}
+&lt;/Directory&gt;</pre>

+<h3><a name="intranet" id="intranet">How can I require HTTPS with strong ciphers, and either basic
+authentication or client certificates, for access to part of the
+Intranet website, for clients coming from the Internet? I still want to allow
+plain HTTP access for clients on the Intranet.</a></h3>
+
+
+ <p>These examples presume that clients on the Intranet have IPs in the range
+ 192.168.1.0/24, and that the part of the Intranet website you want to allow
+ internet access to is <code>/usr/local/apache2/htdocs/subarea</code>.
