Hi,
compatibility note is missing in the doc.
BTW, what is the reason of the LogIOTrackTTFB directive? No impact on
performance if %^FB is not needed?

New Revision: 1673904
URL: http://svn.apache.org/r1673904
Log:
Merge r1671918, r1673113 from trunk:
allow time to first byte (of response headers)
to be logged by mod_logio.
mod_logio was just a conveninent place to do this
w/o writing a new filter or complicating an existing
important one.
Use 'unsigned int' in bitfield
