set cookies name expr set cookie name to expr.
Register a callback that is called before a rewriting. The handler is expected to lookup some cookies and set some global variables.
This API is a temporary hack to allow to migrate from add_arg to the use of cookie, until ppxlib has been upgraded to pass cookies through.
