Apache Module mod_dumpio
Summary
mod_dumpio
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.
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.
