is this rule approx true? as far as it's described in the javadoc:
[1] org.apache.wicket.Session.getSizeInBytes() Size of this session, including all the pagemaps it contains [2] org.apache.wicket.PageMap.getSizeInBytes() Size of this page map in bytes, including a sum of the sizes of all the pages it contains. [3] org.apache.wicket.Session.getPageMaps() A list of all PageMaps in this session. so iterating on pages obtained by [3] and adding each size with [2], then substracting this result to [1], does it provide the accurate size of wicket-session in http-session?
