Its not the html that I'm concerned about, but the state of the
webserver configuration. If I add a new module or change a rewrite rule
I want it to appear on all the machines simultaneously, or as nearly as
possible.
That requires a apache restart, but that requires re-binding to the
port. That is where I get stuck. Even a graceful restart needs to clear
all the connections out before it can re-bind, and with lingering close
+ LVS persistence it appears that it takes a long time sometimes.
