We do something similar. We have implemented a RequestFilter that pushes the
HttpSession ID (if any) onto the Log4j Nested Diagnostics Context (NDC)
before the request, and pops it afterwards.
I guess that the same approach could be used for pushing usernames in the
SLF4J MDC, provided that you can get hold of them from a RequestFilter.
Good to know: Tapestry 5.1 stores @SessionStateObjects in the session under
the key "sso:" + MySessionStateObject.class.getName(). ("aso:" in 5.0.*)
