Hehehe.. I truly don't think the work was done for nothing. I think
Julian has somewhat less familiarity with web caching than with other
types of balancing and doesn't realize the implications of a plain
routing method, which on first glance looks ok, but falls apart under
examination. (Though a hash based netfilter module possibly could
answer the same needs. But someone would have to code it.)
There are a lot of good things about LVS apart from the round robin and
other 'real' balancing methods available. NAT, DR, and Tunnelling,
provides a lot of great flexibility for a web cache cluster...Perhaps a
netfilter module could be written to do the same thing, but LVS+your
scheduler is here now and looks like it will work great (only looked at
the code, haven't installed it and set up a cluster yet).
Just my .02
