Right. I would say that the dictionaries should be
searched in the order of volatility:
POST then GET then COOKIE then PATH
POST is a "one-shot" deal, where GET parameters
often span over multiple requests, COOKIE parameter
are even more persistent, and the PATH is the most
persistent of all (a cookie expires).

If someone wants to change this, they can always
re-implement "value()" in their SitePage.
