I know there was a sample ICAP client ruleset present somewhere here about half a year ago when we did a PoC of McAfee Web Gateway. Sadly I didn't store it anywhere for myself at that point and now I cannot find it anywhere here. Does anyone still have it lying around and can share?
you have a rule set inside MWG's rule library in the UI. Add a new rule set, chose "from Library" find the ICAP section and pick the client rule set.
I don't recall seeing much other than the default rule sets for ICAP client.
Are you sure you're not confusing it with a rule set for ICAP server where a customer application is calling MWG to scan files? That one, i have.
