In his blog entry, More fun with Spring scopes / Java, Eugene Kuleshov shows another potentially interesting use of the custom scope capability introduced in Spring 2.0. He creates a custom scope which binds to specific request URLs. Effectively this allows any data to be bound to a specific page or whatever request specific artifact the current request URL represents, accessible as a regular Spring bean. Think of it as a permanent Page/Request scope, as opposed to the Servlet spec's regular Page/Request scope, which lives only for the lifetime of the current request.
