| <h3>Summary</h3> |
| |
| |
| <p>This module provides the logging of input and output number of |
| bytes received/sent per request. 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 id="quickview"><h3 class="directives">Directives</h3> |

| <h2><a name="formats" id="formats">Custom Log Formats</a></h2> |
| |
| |
| <p>This modules adds two new logging directives. The characteristics of the |
| request itself are logged by placing "<code>%</code>" directives in |
| the format string, which are replaced in the log file by the values as |
| follows:</p> |
| |
| <table class="bordered"><tr class="header"><th>Format String</th> |
| <th>Description</th></tr> |
| <tr><td><code>%...I</code></td> |
| <td>Bytes received, including request and headers, cannot be |
| zero.</td></tr> |
| <tr class="odd"><td><code>%...O</code></td> |
| <td>Bytes sent, including headers, cannot be zero.</td></tr> |
| </table> |
| |
| <p>Usually, the functionality is used like this:</p> |
| |
| <dl> |
| <dt>Combined I/O log format:</dt> |
| <dd><code>"%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" |
| \"%{User-agent}i\" %I %O"</code></dd> |
| </dl> |
