i've read three different explanations about these options, and all three disagree with each other. so let me start with a simple question or two. first, as i read it, you can use the "--limit" option by itself, without --burst-limit. if you do that, then this limit is considered a *hard* limit -- say 5/sec -- and once you hit that limit, you're done until the next time unit. is this correct? adding "--burst-limit", on the other hand, allows you to exceed the first limit, but you end up paying for it down the road. however, i'm still unclear on what the burst-limit represents and how it gets recharged. can someone explain this, preferably with an example containing numbers? rday
