I am interested in reading more about the flowbits option. I have poked around a little on the net and haven't satisfied my curiosity. Does any one know a good writup/doc on the flowbit and or the flow preprocessor. What started my search was trying to understand how the below rule works.
I'm guessing on the nature of your question, but one thing that confused me about flowbits to begin with is that the flowbit names you see pop up in rules are themselves defined by the rules, they aren't some magical reserved words that the flow preprocessor knows about. You can "set" a flowbit as the action part of any rule, and pick any name you want. If you otherwise reference a flowbit in any other rule, it should be defined previously (somewhere), else it will never match (or more correctly, never be "isset"). If you see a flowbit reference you aren't sure about, grep the rules to find out which rules define it.
