Hi Bart,
Thanks for the detailed explanation.
I'll need some time to digest all this.
As I said in this thread: I am not yet sure what I am looking for, I was more thinking aloud.
Your approach sure sounds interesting.

The problem with Seaside is that most requests look pretty much the same and do not contain enough information for after the fact analysis (like http://localhost:8081/welcome?_s=0Sq2_xUpMPSWMOBg.R1&_k=DKeQJiyN2-ye2wCA doesn't say we're on the configuration page).
