Imagine an SES URL processor somewhat analogous to what Django provides, with a regex match that captures specific segments of the incoming URL and passes them to the requested method. Yes I know about ColdCourse, and the related ColdBox plugin etc, I was just thinking about alternate approaches.
So yes, maybe it's unusual, but not irrational, or due to lack of structure in my code. Please, can we not debate my motivation any more? If there are any actual answers to the original question, I'd be interested in hearing them, but frankly I doubt it. I've been doing CF for quite a while, and didn't know of one, so I thought I'd ask around, but this keeps focusing on "larger issues". That's a Good Thing in many cases, but actually not here. I'm asking if there's a language feature I'm not aware of to accomplish this, nothing more.
