Hello all,

mod_backhand 1.1.0 has just been released.  This fixes a major bug as well as
a few quirks.  If you found that mod_backhand just plain wouldn't work before,
this release is likely to have fixed the problem.  Here is the excerpt from
the ChangeLog:

September 4th, 2000 (09.04.2000) -- mod_backhand -- 1.1.0
=================================================
 * Fixed uninitialized variable bug in back_util.c.  The effects were that
        trash values could be found in the server port of the advertised
        service.  This caused different mod_backhand instances to fail when
        proxying.  I could not reproduce this on my Linux machine.  Many
        thanks to Sean Chittenden for the time on his BSD boxes to debug the
        problem.
 * Fixed logic error when calculating byLoad with a bias.  It did not
        calculate biases as the FAQ implied.  Thanks to Blake Millis.
 * Changed the byAge candidacy function to never eliminate oneself.  Under
        high loads, the daemon process was often scheduled so infrequently
        that the local server expired, rendering BackhandSelfRedirect On
        ineffective.
 * Changed two accidental snprintf's to ap_snprintf's for portability.


The unresolved TODO list is as follows:

 o Implement load-weighted randomized request allocation.
 o Make the proxying code more aggressive (with non-blocking I/O).
 o Fix construction of headers in backhand_redirection to avoid possible
        buffer overflow.
 o Caching engine.
 o Change all constants to #define's.
 o Fix code so that is will compile using Sun's ProC compiler.

Many other features are currently being worked on, but did not make it into
this release.  Most of my recent time has been spent working on the course
notes and presentation for the ApacheCon 2000 Europe.  If you can make it to
London in October to participate in a great conference, we would love to see
you there. (www.apachecon.com)
