<h3>Summary</h3>

    <p><code>mod_dumpio</code> allows for the logging of
    all input received by Apache and/or all output sent by
    Apache to be logged (dumped) to the error.log file.
    </p>

    <p>The data logging is done right after SSL decoding (for
    input) and right before SSL encoding (for output). As can
    be expected, this can produce extreme volumes of data,
    and should only be used when debugging problems.</p>
