Subject Re: how to avoid balancer manager nonce?
Date Sat, 01 Sep 2012 15:47:44 GMT
Another alternative would be to have the nonce also possibly
set at config-time and, if unset, then use the uuid. That way
it could also be used as a sort of shared-secret ;)

	ProxySet nonce="applepie!"

Longer term, I think that's a more "strategic" solution.
