hey,
Not sure if they are still actual, but here is what I found:
"Log every authenticated HTTP connection: In many cases, loading a Web page requires more than one connection to be opened. If this option is checked, each and every one of those connections will be logged instead of just the first one to a particular site."
"SLA violation: If a virtual link is defined and the availability parameters defined for that link are not met, that is, the virtual link does not meet the established Service Level Agreement (SLA), this activity generates the appropriate log or alert entry."
Thank you,
