What?
A Common HTTP Log File Format extension for tracking activities of authenticated users, courtesy of their NetID or WebID.
Why?

How?
Simply perform the following steps:
- Enabling HTTP Logging in Virtuoso
- Enabling HTTP Logging Format in Virtuoso
With HTTP Logging Format enabled as detailed the Format String specifier "%{NetId}e" enables the logging of a users NetID or WebID (being a sub-set of NetID) to be logged.
