103    supported:</p>
104    <ul>
105    <li><b>%a</b> - Remote IP address</li>
106    <li><b>%A</b> - Local IP address</li>

130    There is also support to write information from the cookie, incoming
131    header, the Session or something else in the ServletRequest.
132    It is modeled after the apache syntax:
133    <ul>
134    <li><b><code>%{xxx}i</code></b> for incoming headers</li>
135    <li><b><code>%{xxx}o</code></b> for outgoing response headers</li>
136    <li><b><code>%{xxx}c</code></b> for a specific cookie</li>
137    <li><b><code>%{xxx}r</code></b> xxx is an attribute in the ServletRequest</li>
138    <li><b><code>%{xxx}s</code></b> xxx is an attribute in the HttpSession</li>
139    </ul>

142
143    <p>The shorthand pattern name <code>common</code> (which is also the
144    default) corresponds to <strong>'%h %l %u %t "%r" %s %b'</strong>.</p>
145
146    <p>The shorthand pattern name <code>combined</code> appends the
147    values of the <code>Referer</code> and <code>User-Agent</code> headers,
148    each in double quotes, to the <code>common</code> pattern
149    described in the previous paragraph.</p>
