Can Urchin process a log file with two different line formats?
The Primary and Secondary lines in the log format are intended to support ecommerce log files, where the secondary lines are related to the primary lines (e.g. secondary per-item logging associated the primary transaction record). It’s not a mechanism that can be used for reading two different (and independent) types of log lines in the same log. There’s no support in Urchin for doing the latter.
