byLoad
byLoad [bias - a floating point number] Default none Directory
The byLoad
function produces a list of servers
sorted by load. The bias argument, a
floating-point number, lets you prefer the server that originally
catches the request by offsetting the extra cost of forwarding it. In
other words, it may pay to let the first server cope with the
request, even if it is not quite the least loaded. Sensible values
would be in the region of 0 to 1.0.
