<summary>
|
|
|
|
<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 <module>mod_log_config</module>.</p>

<title>Custom Log Formats</title>
|
|
|
|
<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 border="1" style="zebra">
|
|
<tr><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><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>
|
