Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit X-Virus-Checked: Checked by ClamAV on apache.org Is there a means of looking up the current value of a configuration variable, in particular one that is not explicitly set in one of the .conf files? For instance if I wanted to find the value of "io.file.buffer.size" (just a random example) how would I go about it? Thanks - Adam Phelps
