      implemented by the <a href="http://www.pcre.org">PCRE</a> engine and
      have the same syntax as those in <a href="http://www.perl.com">perl
      5</a>.</p>

      <p>If you are matching positive (<code>=</code>), you can capture
      grouped parts of the regular expression. The captured parts are
      stored in the special variables <code>$1</code> ..
      <code>$9</code>.</p>

      <div class="example"><h3>Example</h3><p><code>
        &lt;!--#if expr="$QUERY_STRING = /^sid=([a-zA-Z0-9]+)/" --&gt;<br />
        <span class="indent">
          &lt;!--#set var="session" value="$1" --&gt;<br />
        </span>
        &lt;!--#endif --&gt;
      </code></p></div>
      </dd>

      <dt><code><var>string1</var> &lt; <var>string2</var><br />
       <var>string1</var> &lt;= <var>string2</var><br />
       <var>string1</var> &gt; <var>string2</var><br />
       <var>string1</var> &gt;= <var>string2</var></code></dt>

      <dd>Compare <var>string1</var> with <var>string2</var>. Note, that
      strings are compared <em>literally</em> (using
      <code>strcmp(3)</code>). Therefore the string "100" is less than
      "20".</dd>

      <dt><code>( <var>test_condition</var> )</code></dt>
      <dd>true if <var>test_condition</var> is true</dd>

      <dt><code>! <var>test_condition</var></code></dt>
      <dd>true if <var>test_condition</var> is false</dd>

      <dt><code><var>test_condition1</var> &amp;&amp;
        <var>test_condition2</var></code></dt>
      <dd>true if both <var>test_condition1</var> and
      <var>test_condition2</var> are true</dd>

      <dt><code><var>test_condition1</var> ||
        <var>test_condition2</var></code></dt>
      <dd>true if either <var>test_condition1</var> or
      <var>test_condition2</var> is true</dd>
    </dl>

    <p>"<code>=</code>" and "<code>!=</code>" bind more tightly than
    "<code>&amp;&amp;</code>" and "<code>||</code>". "<code>!</code>" binds
    most tightly. Thus, the following are equivalent:</p>

    <div class="example"><p><code>
      &lt;!--#if expr="$a = test1 &amp;&amp; $b = test2" --&gt;<br />
      &lt;!--#if expr="($a = test1) &amp;&amp; ($b = test2)" --&gt;
    </code></p></div>

    <p>The boolean operators <code>&amp;&amp;</code> and <code>||</code>
    share the same priority. So if you want to bind such an operator more
    tightly, you should use parentheses.</p>

    <p>Anything that's not recognized as a variable or an operator
    is treated as a string. Strings can also be quoted:
    <code>'string'</code>. Unquoted strings can't contain whitespace
    (blanks and tabs) because it is used to separate tokens such as
    variables. If multiple strings are found in a row, they are
    concatenated using blanks. So,</p>

    <div class="example"><p><code><var>string1</var>&nbsp;&nbsp;&nbsp;&nbsp;<var>string2</var></code> results in <code><var>string1</var>&nbsp;<var>string2</var></code><br />
      <br />
      and<br />
      <br />
      <code>'<var>string1</var>&nbsp;&nbsp;&nbsp;&nbsp;<var>string2</var>'</code> results in <code><var>string1</var>&nbsp;&nbsp;&nbsp;&nbsp;<var>string2</var></code>.</p></div>

    <p>The <code class="directive">XBitHack</code> directive controls the parsing
    of ordinary html documents. This directive only affects files associated
    with the MIME type <code>text/html</code>. <code class="directive">XBitHack</code> can take on the following values:</p>

    <dl>
      <dt><code>off</code></dt>
      <dd>No special treatment of executable files.</dd>

      <dt><code>on</code></dt>
      <dd>Any <code>text/html</code> file that has the user-execute bit
      set will be treated as a server-parsed html document.</dd>

      <dt><code>full</code></dt>
      <dd>As for <code>on</code> but also test the group-execute bit.
      If it is set, then set the <code>Last-modified</code> date of the
      returned file to be the last modified time of the file. If
      it is not set, then no last-modified date is sent. Setting
      this bit allows clients and proxies to cache the result of
      the request. 

      <div class="note"><h3>Note</h3>
      <p>You would not want to use the full option, unless you assure the
      group-execute bit is unset for every SSI script which might <code>#include</code> a CGI or otherwise produces different output on
      each hit (or could potentially change on subsequent requests).</p>
