+       # NOTE: In httpd 2.0, unlike 1.3, the %b and %B format strings do not
+       # represent the number of bytes sent to the client, but simply the size in
+       # bytes of the HTTP response (which will differ, for instance, if the
+       # connection is aborted, or if SSL is used). The %O format provided by
+       # mod_logio will log the actual number of bytes sent over the network.
+       #
+       # So if you need to log actual bytes sent (for example log analyzing),
+       # install mod_logio and use %O instead of %b.
