<p><strong>Summary</strong></p>
|
||
<p>This module provides the logging of input and output number of bytes received
|
||
and sent per request. The numbers reflect the actual bytes 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. The numbers will correctly reflect any changes made by encryption.
|
||
</p>
|
||
<p>This module requires <a href="rzaiemod_log_config.htm">Module
|
||
mod_log_config</a>, and is loaded by default. No LoadModule statement
|
||
is required. </p>
|
||
<p>This module adds two new logging formats. The characteristics of the request
|
||
itself are logged by placing <samp class="codeph">"%"</samp> directives in the format
|
||
string, which are replaced in the log file by the values as follows: <samp class="codeph">Format String
|
||
Description %...I</samp> </p>
|
||
<p>Bytes received, including request and headers, cannot be zero (<samp class="codeph">%...O</samp>).
|
||
Bytes sent, including headers, cannot be zero.</p>
|
||
<p><strong>Format String Description</strong></p>
