SSIEndTag   "%&gt;"</pre>


    <p>The example given above, which also specifies a matching
    <code class="directive"><a href="#ssiendtag">SSIEndTag</a></code>, will
    allow you to use SSI directives as shown in the example
    below:</p>

    <div class="example"><h3>SSI directives with alternate start and end tags</h3><p><code>
      &lt;%printenv %&gt;
    </code></p></div>

<ul>

<div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="directive-section"><h2><a name="SSITimeFormat" id="SSITimeFormat">SSITimeFormat</a> <a name="ssitimeformat" id="ssitimeformat">Directive</a></h2>
<table class="directive">
<tr><th><a href="directive-dict.html#Description">Description:</a></th><td>Configures the format in which date strings are
displayed</td></tr>
<tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>SSITimeFormat <var>formatstring</var></code></td></tr>

<tr><th><a href="directive-dict.html#Override">Override:</a></th><td>All</td></tr>
<tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Base</td></tr>
<tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_include</td></tr>
</table>
<p>This directive changes the format in which date strings are displayed
    when echoing <code>DATE</code> environment variables. The
    <var>formatstring</var> is as in <code>strftime(3)</code> from the
    C standard library.</p>

    <p>This directive has the same effect as the <code>&lt;!--#config
    timefmt=<var>formatstring</var> --&gt;</code> element.</p>

    <pre class="prettyprint lang-config">SSITimeFormat "%R, %B %d, %Y"</pre>


    <p>The above directive would cause times to be displayed in the
    format "22:26, June 14, 2002".</p>

    <p>This directive changes the string that <code class="module"><a href="../mod/mod_include.html">mod_include</a></code>
    displays when a variable is not set and "echoed".</p>

    <pre class="prettyprint lang-config">SSIUndefinedEcho "&lt;!-- undef --&gt;"</pre>

    <p>The <code class="directive">XBitHack</code> directive controls the parsing
    of ordinary html documents. This directive only affects files associated
    with the <a class="glossarylink" href="../glossary.html#mime-type" title="see glossary">MIME-type</a> <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>

      <p>The <code class="directive"><a href="#ssilastmodified">SSILastModified</a></code>
      directive takes precedence over the
      <code class="directive"><a href="#xbithack">XBitHack</a></code> directive when
      <code class="directive"><a href="#ssilastmodified">SSILastModified</a></code> is set to
      <code>on</code>.</p>
      </div>

      </dd>
