Just to be clear, we are planning on extensively using the @pm/@pmf to do fast pre-qualification of groups of rules. If these rules match, then we will execute the optimized regular expression rules. What we can do is provide the smaller regex sources with Apache comments prior to the rules. So, you would really have two ways of knowing the source data for the optimized regexes: 1) The plain text string pm data, and 2) The smaller, individual regexes. -Ryan > >Klaubert Herr > >On Wed, Jun 6, 2012 at 11:23 AM, Ryan Barnett <rbarn...@trustwave.com> >wrote: >> One of the items we are considering with the CRS v3.0 update is to start >> from scratch with all of the rule IDs.
