title: zlib.output_compression and output_buffering
body: <p>Can I compress output by setting the <code>zlib.output_compression</code> directive to <code>on</code>, and then set the <code>output_buffering</code> directive to <code>off</code>?</p>
  
  <p>Secondly I read that I can set a number value to the <code>zlib.output_compression</code> directive which specifies a specific buffer size.
  But what if I also set the <code>output_buffering</code> directive to a different number value of bytes? What will be the max buffer size?</p>
