The numbers reflect the actual bytes as received on the network, which then takes into account the headers and bodies of requests and responses. The counting is done before SSL/TLS on input and after SSL/TLS on output, so the numbers will correctly reflect any changes made by encryption.</p> <p>This module requires <code class="module"><a href="../mod/mod_log_config.html">mod_log_config</a></code>.</p> <div class="note">When KeepAlive connections are used with SSL, the overhead of the SSL handshake is reflected in the byte count of the first request on the connection. When per-directory SSL renegotiation occurs, the bytes are associated with the request that triggered the renegotiation.</div> </div> <div id="quickview"><h3 class="directives">Directives</h3> <p>This module provides no directives.</p> <h3>Topics</h3> <ul id="topics"> <li><img alt="" src="../images/down.gif" /> <a href="#formats">Custom Log Formats</a></li> </ul><h3>See also</h3> <ul class="seealso"> <li><code class="module"><a href="../mod/mod_log_config.html">mod_log_config</a></code></li> <li><a href="../logs.html">Apache Log Files</a></li> </ul><ul class="seealso"><li><a href="#comments_section">Comments</a></li></ul></div> <div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> <div class="section"> <h2><a name="formats" id="formats">Custom Log Formats</a></h2> <p>This modules adds two new logging directives.
