Here is what Barracuda is using for the event name:

target = req.getServletPath();

Christian can you speak to why this was used? I think I can easily fix 
this by just using the getRequestURI() method. In fact further down in 
the code getRequestURI() is used if target is null or empty. There is 
also code to strip off the extra path info and get just the event name. 
This is easy to change, but I would like to understand why it was done 
this way to begin with, to make sure that i am not overlooking something.
