Writing flow logs in an ra client

[Chris Carton]

I'm writing an ra client and I have a question about writing the flow log 
files.

I understand that I have to write the contents of ArgusInput->ArgusInitCon as 
a header for the log file or ra can't read it.

If I'm always reading flows by connecting to a live argus server, how often 
will that data (ArgusInput->ArgusInitCon) change? If it does change I assume 
that I look for a mar record of some sort that tells me?

Thanks!

Chris
