<h2><a name="browsersession" id="browsersession">Keeping sessions on the browser</a></h2>
- <p>Where keeping track of a session on a server is too resource
- intensive or inconvenient, the option exists to store the contents
- of the session within a cookie on the client browser instead.</p>
+ <p>In high traffic environments where keeping track of a session on a
+ server is too resource intensive or inconvenient, the option exists to store
+ the contents of the session within a cookie on the client browser instead.</p>
<p>This has the advantage that minimal resources are required on the
server to keep track of sessions, and multiple servers within a server
where the session will be stored. In this example, the session will be
stored on the browser, in a cookie called <code>session</code>.</p>
- <div class="example"><h3>Browser based session</h3><p><code>
- Session On<br />
- SessionCookieName session path=/<br />
- </code></p></div>
+ <div class="example"><h3>Browser based session</h3><pre class="prettyprint lang-config">Session On
+SessionCookieName session path=/</pre>
+</div>
<p>The session is not useful unless it can be written to or read from. The
following example shows how values can be injected into the session through
the use of a predetermined HTTP response header called
<code>X-Replace-Session</code>.</p>
- <div class="example"><h3>Writing to a session</h3><p><code>
- Session On<br />
- SessionCookieName session path=/<br />
- SessionHeader X-Replace-Session<br />
- </code></p></div>
+ <div class="example"><h3>Writing to a session</h3><pre class="prettyprint lang-config">Session On
+SessionCookieName session path=/
+SessionHeader X-Replace-Session</pre>
+</div>
<p>The header should contain name value pairs expressed in the same format
as a query string in a URL, as in the example below. Setting a key to the
empty string has the effect of removing that key from the session.</p>
- <div class="example"><h3>CGI to write to a session</h3><p><code>
- #!/bin/bash<br />
- echo "Content-Type: text/plain"<br />
- echo "X-Replace-Session: key1=foo&key2=&key3=bar"<br />
- echo<br />
- env<br />
- </code></p></div>
+ <div class="example"><h3>CGI to write to a session</h3><pre class="prettyprint lang-sh">#!/bin/bash
+echo "Content-Type: text/plain"
+echo "X-Replace-Session: key1=foo&key2=&key3=bar"
+echo
+env</pre>
+</div>
<p>If configured, the session can be read back from the HTTP_SESSION
environment variable. By default, the session is kept private, so this
has to be explicitly turned on with the
<code class="directive"><a href="#sessionenv">SessionEnv</a></code> directive.</p>
- <div class="example"><h3>Read from a session</h3><p><code>
- Session On<br />
- SessionEnv On<br />
- SessionCookieName session path=/<br />
- SessionHeader X-Replace-Session<br />
- </code></p></div>
+ <div class="example"><h3>Read from a session</h3><pre class="prettyprint lang-config">Session On
+SessionEnv On
+SessionCookieName session path=/
+SessionHeader X-Replace-Session</pre>
+</div>
<p>Once read, the CGI variable <code>HTTP_SESSION</code> should contain
the value <code>key1=foo&key3=bar</code>.</p>
placed on the browser using the <code class="module"><a href="../mod/mod_session_crypto.html">mod_session_crypto</a></code>
module.</p>
- <div class="example"><h3>Browser based encrypted session</h3><p><code>
- Session On<br />
- SessionCryptoPassphrase secret<br />
- SessionCookieName session path=/<br />
- </code></p></div>
+ <div class="example"><h3>Browser based encrypted session</h3><pre class="prettyprint lang-config">Session On
+SessionCryptoPassphrase secret
+SessionCookieName session path=/</pre>
+</div>
<p>The session will be automatically decrypted on load, and encrypted on
save by Apache, the underlying application using the session need have
<p>Standard cookie parameters can be specified after the name of the cookie,
as in the example below.</p>
- <div class="example"><h3>Setting cookie parameters</h3><p><code>
- Session On<br />
- SessionCryptoPassphrase secret<br />
- SessionCookieName session path=/private;domain=example.com;httponly;secure;<br />
- </code></p></div>
+ <div class="example"><h3>Setting cookie parameters</h3><pre class="prettyprint lang-config">Session On
+SessionCryptoPassphrase secret
+SessionCookieName session path=/private;domain=example.com;httponly;secure;</pre>
+</div>
<p>In cases where the Apache server forms the frontend for backend origin servers,
it is possible to have the session cookies removed from the incoming HTTP headers using
<code class="module"><a href="../mod/mod_auth_form.html">mod_auth_form</a></code> saves the user's login name and password within
the session.</p>
- <div class="example"><h3>Form based authentication</h3><p><code>
- Session On<br />
- SessionCryptoPassphrase secret<br />
- SessionCookieName session path=/<br />
- AuthFormProvider file<br />
- AuthUserFile conf/passwd<br />

+<h2><a name="integration" id="integration">Integrating Sessions with External Applications</a></h2>
+
+ <p>In order for sessions to be useful, it must be possible to share the contents
+ of a session with external applications, and it must be possible for an
+ external application to write a session of its own.</p>
+
+ <p> A typical example might be an application that changes a user's password set by
+ <code class="module"><a href="../mod/mod_auth_form.html">mod_auth_form</a></code>. This application would need to read the current
+ username and password from the session, make the required changes to the user's
+ password, and then write the new password to the session in order to provide a
+ seamless transition to the new password.</p>
+
+ <p>A second example might involve an application that registers a new user for
+ the first time. When registration is complete, the username and password is
+ written to the session, providing a seamless transition to being logged in.</p>
+
+ <dl>
+ <dt>Apache modules</dt>
+ <dd>Modules within the server that need access to the session can use the
+ <strong>mod_session.h</strong> API in order to read from and write to the
+ session. This mechanism is used by modules like <code class="module"><a href="../mod/mod_auth_form.html">mod_auth_form</a></code>.
+ </dd>
+
+ <dt>CGI programs and scripting languages</dt>
+ <dd>Applications that run within the webserver can optionally retrieve the
+ value of the session from the <strong>HTTP_SESSION</strong> environment
+ variable. The session should be encoded as a
+ <strong>application/x-www-form-urlencoded</strong> string as described by the
+ <a href="http://www.w3.org/TR/html4/">HTML specification</a>. The environment
+ variable is controlled by the setting of the
+ <code class="directive"><a href="#sessionenv">SessionEnv</a></code> directive. The session
+ can be written to by the script by returning a
+ <strong>application/x-www-form-urlencoded</strong> response header with a name
+ set by the <code class="directive"><a href="#sessionheader">SessionHeader</a></code>
+ directive. In both cases, any encryption or decryption, and the reading the
+ session from or writing the session to the chosen storage mechanism is handled
+ by the <code class="module"><a href="../mod/mod_session.html">mod_session</a></code> modules and corresponding configuration.
+ </dd>
+
+ <dt>Applications behind <code class="module"><a href="../mod/mod_proxy.html">mod_proxy</a></code></dt>
+ <dd>If the <code class="directive"><a href="#sessionheader">SessionHeader</a></code>
+ directive is used to define an HTTP request header, the session, encoded as
+ a <strong>application/x-www-form-urlencoded</strong> string, will be made
+ available to the application. If the same header is provided in the response,
+ the value of this response header will be used to replace the session. As
+ above, any encryption or decryption, and the reading the session from or

+ when only the expiry time has changed. This can be used to make a website
+ more efficient or reduce load on a database when using

+
+ <p>Setting the interval to zero disables this directive, and the session
+ expiry is refreshed for each request.</p>
+
+ <p>This directive only has an effect when combined with

+ expiry. Sessions without an expiry are only written when the data stored in

+
+ <div class="warning"><h3>Warning</h3>
